The Barrett Model 98B (also known as the Barrett Model 98 Bravo) is a bolt-action sniper rifle chambered in .338 Lapua Magnum (8.6×70mm or 8.58×70mm) and manufactured by Barrett Firearms Manufacturing. The Model 98B was officially announced in October 2008, and became available for sale in early 2009, with an MSRP of $4,495.00.[1]

Key Information

Sub-MOA shot groupings of 0.73 inches (19 mm) at 100 yards (91 m),[1] 1.3 inches (33 mm) at 200 yards (180 m), and 4.05 inches (103 mm) at 800 yards (730 m) were obtained.[4]

Overview

[edit]
The Barrett M98B

Barrett engineers began designing the Model 98B in 1997,[1] with a goal of developing a precision tactical .338 Lapua rifle not based on any sporting rifles. The initial semi-auto design, the Model 98 was unveiled at the 1998 SHOT Show, but never went into full production. In past years, Ronnie Barrett's son, Chris, revived the company's interest in the .338 rifle.[1]

Many of the Model 98B's features are inspired by Stoner's AR-15/M16; the hinged aluminum upper and lower receivers, ergonomic pistol grip and thumb operated safety are all borrowed from Stoner's design. The upper receiver also features a full-length (18.125 inches (460.4 mm)) 1913 style Picatinny rail for mounting optics, lasers, etc.,[2] and two additional accessory rails are mounted forward of the main rail on each side of the upper.[1]

The Model 98B also features a fluted medium-heavy 27-inch (690 mm) barrel made of 4150 MIL-B-11595 steel. The barrel is rifled in a six groove, 1:10" right hand twist pattern,[1] and features a two-port muzzle brake threaded on and indexed by a jam nut. The bolt rides in a new "bolt guide" design, consisting of two tubular glass-filled polymer guides which have been infused with Teflon.[2][1] These guides allow the bolt to travel better, as well as reducing the need for lubrication, and helping to seal the ejection and bolt handle ports from dirt. The bolt head is made of case-hardened 8620 steel, features nine lugs (three sets of three), and is attached to the bolt body with a crosspin.[1] This separate bolt head design allows for simple caliber changes, as well as future pre-headspaced barrel and bolt-head sets.[1]

The lower receiver is forged from 7075 aluminum,[2] can mount any type of AR-15/M-16 pistol grip, and features an ambidextrous magazine latch just forward of the integral trigger guard. Also featured within the lower receiver is the rifle's trigger assembly. The trigger assembly can be removed from the receiver as a single unit, and features adjustment screws for weight (2 to 4 lbs.) and overtravel, as well as a reversible AR-15/M-16 style thumb safety.[1]

The skeletonized buttstock is also integral to the lower receiver, and features a thick Sorbothane buttpad with spacers for pull adjustment, a polymer cheekpiece with 0.75 inches (19 mm) of variable comb height, and an adjustable monopod.[2][1] The rifle also comes from the factory with a Harris brand S-BR bipod attached to the fore-end.

The Model 98B was featured both on the cover, and in an article, of the April 2009 issue of American Rifleman magazine.[1]

MRAD

[edit]
Main article: Barrett MRAD (Multi-Role Adaptive Design)

Barrett's offering for USSOCOM's Precision Sniper Rifle contract, the MRAD, is derived from the Model 98B. Changes to the rifle include cutting back the fixed stock and integrating a folding adjustable stock, a Desert Tan finish color, and a front loading quick change barrel for caliber change. As of 2011, the only barrel and caliber offered was a 24.5 in (620 mm) fluted barrel with a 1:10" right hand twist chambered for .338 Lapua Magnum.[5][6][7]

Safety recall

[edit]

On September 9, 2009, Barrett released a recall notice regarding the Model 98B. They determined that if the rifle is dropped or subjected to a significant impact, it could accidentally discharge. A modification to the lower receiver was required to ensure user safety.[8]

View on Grokipedia
from Grokipedia
The Barrett Model 98B is a bolt-action precision rifle manufactured by Barrett Firearms Manufacturing, designed primarily for long-range tactical and sniper applications with chambering in the powerful .338 Lapua Magnum cartridge.[1] Introduced as a dedicated tactical firearm not derived from sporting rifle platforms, it emphasizes accuracy, modularity, and user customization for military, law enforcement, and competitive shooting.[2] Development of the Model 98B began in 1997 under the direction of Barrett engineers, including Chris Barrett, with the goal of creating a high-precision bolt-action rifle to complement the company's semi-automatic offerings like the Model 82 and Model 99.[1] The rifle entered production in 2008, evolving from an initial .338 Lapua focus to include multi-caliber variants by 2014, such as .300 Winchester Magnum, 7mm Remington Magnum, .308 Winchester, 6.5 Creedmoor, and .260 Remington.[3] It received the NRA's American Rifleman Golden Bullseye Award for Rifle of the Year in 2010, recognizing its innovative design and performance.[4] The model was discontinued in the late 2010s. Key specifications for the standard .338 Lapua Magnum configuration include an overall length of 49.75 inches, a 27-inch match-grade barrel with a 1:10-inch twist rate (shorter 20-inch or 24-inch options available in other calibers), and an unloaded weight of approximately 13.5 pounds.[5] The rifle operates via a manual bolt-action repeater mechanism with a three-lug rotating bolt, fed by detachable 10-round polymer magazines, and incorporates a thumb-operated safety, adjustable match-grade trigger (typically 3-5 pounds pull), and an adjustable cheek riser for enhanced ergonomics.[3] A distinctive muzzle brake reduces recoil significantly, enabling effective fire at extended ranges beyond 1,000 yards, while the chassis features KeyMod rail sections for accessory attachment in Tactical variants.[6] The Model 98B was produced in two primary configurations: the Tactical model, optimized for precision shooting with an extended Picatinny rail, tungsten gray or black Cerakote finish, and muzzle brake; and the lighter Fieldcraft variant, geared toward hunting with threaded barrels, adaptive camouflage options, and reduced weight around 11 pounds in calibers like .300 Winchester Magnum.[3] Both deliver sub-MOA accuracy from the factory, thanks to the free-floating barrel and precision-machined receiver.[7] However, a 2009 recall addressed a potential safety issue where significant impact could cause accidental discharge, underscoring ongoing refinements in durability.[8]

Development and History

Origins and Design Process

The Barrett Model 98B originated from a design initiative launched in 1997. Chris Barrett, son of Barrett Firearms founder Ronnie Barrett, who began full-time work in 1996 and served as lead designer from 2000, contributed significantly to its development by seeking to create a tactical precision rifle chambered in .338 Lapua Magnum that emphasized military applicability over sporting purposes.[9][10] This effort addressed the demand for a lighter-weight alternative to the heavier .50 BMG-chambered Barrett M82, providing enhanced portability for long-range tactical engagements while maintaining high accuracy and durability in adverse conditions.[1] The project drew significant influence from an earlier prototype, the semi-automatic Model 98, which was unveiled at the 1998 SHOT Show but discontinued shortly thereafter due to insufficient market adoption and production challenges.[9][2] Recognizing the limitations of the gas-operated semi-automatic mechanism in achieving consistent precision under tactical stresses, Barrett's team pivoted to a bolt-action configuration, prioritizing reliability, simpler maintenance, and sub-minute-of-angle accuracy for sniper applications.[9] Central to the design process was the integration of an AR-style receiver system with the bolt-action mechanism to enhance modularity, featuring hinged aluminum upper and lower receivers inspired by the AR-15 platform for quick disassembly and accessory mounting via Picatinny rails.[9] Engineers focused on a lightweight 7000-series aluminum chassis for the upper receiver and 7075 aluminum for the lower, balancing strength with reduced weight, alongside the development of a user-adjustable single-stage trigger mechanism— a novel feature for Barrett production rifles at the time—allowing customization of pull weight between 2 and 4 pounds to suit operator preferences.[9] This modular approach facilitated easy barrel swaps and mission-specific adaptations, as encapsulated in the rifle's purpose-built ethos: "to withstand adverse conditions, to be easily adaptable to any mission using the appropriate accessories, and to take advantage of the ergonomic user interfaces familiar to contemporary soldiers."[9] The design later influenced the Multi-Role Adaptive Design (MRAD) variant to meet evolving military requirements.[11]

Production Timeline and Recognition

The Barrett Model 98B entered production following an initial design process that began in 1997, with the rifle officially becoming available for civilian purchase in early 2009 after prototype testing and announcement in late 2008; initial manufacturing emphasized the .338 Lapua Magnum chambering to meet demands for long-range precision shooting.[12][13] In recognition of its innovative bolt-action design and exceptional accuracy, the Model 98B was awarded the 2010 NRA American Rifleman Golden Bullseye Award for Rifle of the Year, presented at the NRA Annual Meeting and highlighting its contributions to tactical rifle advancements.[4][14] Production evolved in 2014 with the introduction of Tactical and Fieldcraft variants featuring a lighter receiver design and KeyMod rail system for improved adaptability and reduced weight, enhancing its appeal for field use.[3][7] Production of the Model 98B was discontinued around 2019.[15][16]

Design and Features

Key Components

The Barrett Model 98B employs a magazine-fed bolt-action repeater mechanism with a multi-lugged rotary bolt that provides a secure lockup directly to the barrel, facilitating reliable manual cycling and high-precision operation through a 60-degree bolt lift and efficient extractor system.[9][17] Inspired by the AR-15 platform, the rifle features a hinged aluminum receiver assembly consisting of a 7000-series upper and 7075-series lower, which enhances modularity by allowing straightforward disassembly and customization while incorporating an integral 18.125-inch Mil-Spec Picatinny rail on the upper for optics and accessory mounting.[9][17] Ergonomic elements include an adjustable polymer cheek riser offering up to 0.75-inch vertical variance for optimal sight alignment, an AR-compatible pistol grip for secure handling, a reversible thumb-operated rotating safety lever for ambidextrous functionality, and a detachable 10-round polymer box magazine that feeds cartridges smoothly into the chamber.[9][17] The barrel is crafted from 4150 CMV steel with a six-groove, 1:10 right-hand twist rate designed to stabilize .338 Lapua Magnum projectiles, and fluted configurations with eight longitudinal flutes are offered to promote heat dissipation and reduce weight without compromising rigidity.[9][17] This design results in a lighter overall weight compared to semi-automatic predecessors like the M82, improving field handling for long-range applications.[1][18]

Technical Specifications

The Barrett Model 98B is a bolt-action precision rifle primarily chambered in .338 Lapua Magnum, with compatibility for other calibers such as .300 Winchester Magnum through barrel and bolt changes.[17][5] Its standard configuration features an overall length of 49.75 inches (126.36 cm) and a barrel length of 27 inches (68.58 cm), though a 20-inch (50.8 cm) barrel option is available for reduced portability.[17][5] The rifle weighs 13.5 pounds (6.12 kg) empty without optics, contributing to its stability for long-range shooting.[17][5] Key performance parameters include an effective range of up to 1,500 meters when using .338 Lapua Magnum ammunition, with a muzzle velocity of approximately 2,900 feet per second (fps) from the 27-inch barrel.[19][9] The feed system utilizes a detachable 10-round polymer box magazine, and the barrel employs a 1:10-inch right-hand twist rate to stabilize heavy projectiles.[17][5] Construction emphasizes durability and weight reduction, with the receiver made from 7075 and 7000-series aluminum alloys and the fluted barrel from 4150 steel.[9][17]

Variants

Civilian Models

The Barrett Model 98B civilian models are configured for non-military applications such as long-range hunting, precision target shooting, and tactical sporting use, emphasizing modularity, reduced weight, and compatibility with civilian accessories. These variants build on the rifle's foundational bolt-action repeater design, incorporating adjustable match-grade triggers, detachable 10-round polymer magazines, and M1913 Picatinny rails for optics mounting.[3][20] The Model 98B Tactical features a 24-inch heavy-contour barrel chambered in .300 Winchester Magnum, providing a balance of maneuverability and long-range accuracy with a 1:10-inch twist rate and integrated Barrett muzzle brake to mitigate recoil. Weighing approximately 13.5 pounds, it includes a full-length 17-inch Picatinny rail system for mounting accessories like scopes and bipods, making it suitable for tactical civilian competitions and varmint hunting. This configuration is also available in .338 Lapua Magnum with similar barrel options for extended-range precision.[21][22][23] Introduced in 2014, the Model 98B Fieldcraft prioritizes portability with a lightweight aluminum chassis weighing under 12 pounds—typically 9.25 pounds in configurations like 6.5 Creedmoor—while maintaining sub-MOA accuracy for demanding field conditions. It incorporates a KeyMod handguard for customizable modular attachments, such as lights or grips, and is optimized for hunting large game and long-range competitions with lighter-contour barrels in calibers including .300 Winchester Magnum, 7mm Remington Magnum, and .308 Winchester. The design's adjustable cheek piece and thumb-operated safety enhance ergonomics for civilian users in varied terrains.[3][20][24] Both civilian models are offered in multiple calibers such as .338 Lapua Magnum and .300 Winchester Magnum to accommodate diverse shooting needs, with suggested retail prices ranging from $3,999 to $4,499 as of recent listings, though market values can vary. Their compatibility with custom optics via the extended rail systems allows integration with high-magnification scopes for precision applications.[3][1][25]

Military Adaptation (MRAD)

The Barrett MRAD (Multi-Role Adaptive Design) represents the militarized evolution of the Model 98B platform, introduced in 2011 to address the demands of modern special operations sniping. Developed as a direct derivative of the civilian-oriented 98B, the MRAD incorporates a quick-change barrel system that enables rapid caliber interchanges without specialized tools, supporting configurations in 7.62x51mm NATO, .300 Norma Magnum, and .338 Norma Magnum to optimize for varying mission profiles from close-quarters support to extreme long-range engagements. This adaptability stems from the rifle's modular chassis, allowing operators to swap barrels in under two minutes while maintaining sub-MOA accuracy across calibers.[26][27][28] Key enhancements in the MRAD focus on operational mobility and precision in combat environments, including a folding stock that reduces the rifle's footprint for transport—collapsing to 39.9 inches overall length—while locking securely for stability during firing. The upper receiver integrates a 30 MOA canted Picatinny rail to extend effective engagement ranges beyond 1,500 meters without optic adjustments, paired with tool-less barrel removal for field maintenance under duress. These features contributed to the MRAD's selection in 2019 for the U.S. Special Operations Command (USSOCOM) Advanced Sniper Rifle (ASR) contract, valued at nearly $50 million, replacing legacy systems like the Remington MSR with a more versatile platform.[29][30][31] Weighing approximately 13.9 pounds in its 7.62x51mm NATO configuration (unloaded, without optics), the MRAD emphasizes enhanced modularity for integration with suppressors, such as the Barrett AML-338 series, which mitigates muzzle flash and signature during suppressed fire while handling the recoil of all supported calibers. Its aluminum and polymer construction, finished in durable Cerakote, ensures reliability in adverse conditions, including extreme temperatures, dust, and humidity, as validated through rigorous USSOCOM testing. Designated as the Mk 22 Mod 0 upon adoption, the rifle has been procured for U.S. special operations forces, with initial deliveries commencing in 2021 to equip units like Marine Corps Scout Snipers.[32][33][34]

Operational Use and Issues

Users and Applications

The Barrett Model 98B and its military variant, the MRAD designated as the Mk 22 Mod 0, have been primarily adopted by the U.S. Special Operations Command for long-range precision sniping roles, enabling engagements beyond 1,500 meters in calibers such as .300 Norma Magnum and .338 Norma Magnum.[35][36] As of November 2024, the U.S. Marine Corps has achieved Full Operational Capability with the Mk 22 Mod 0.[37] This adoption supports special forces operations requiring modular caliber conversion and sub-MOA accuracy in diverse combat environments.[32] Limited uptake by other international forces includes Norway's special operations units, New Zealand Army, and Israel's special police (Yaman), where the rifle serves similar extended-range sniper duties.[36] In law enforcement contexts, the Model 98B is employed by SWAT teams for urban counter-sniper operations, prized for its rapid bolt manipulation and balance during high-risk maneuvers.[19] Configurations chambered in .300 Winchester Magnum are particularly valued for their accuracy and versatility in tactical scenarios, allowing precise shots in constrained environments.[21] Among civilians, the Model 98B finds popularity in competitive long-range shooting events and big-game hunting, where its lightweight chassis and match-grade trigger facilitate consistent performance on distant targets or large game.[38][39] The rifle has also appeared in films and television productions depicting tactical and sniper scenarios, enhancing its cultural recognition.[40]

Safety Recall

In September 2009, Barrett Firearms Manufacturing announced a voluntary safety recall for early production Model 98B rifles due to a potential risk of accidental discharge if the firearm was dropped or subjected to significant impact.[8] The issue affected rifles with serial numbers ranging from 98B00003 to 98B00775, encompassing approximately 773 units from pre-2010 production.[8] The vulnerability originated in the fire control group, specifically the receiver safety latch, which could fail under impact and allow unintended firing.[8] Barrett addressed this through a free factory modification program, replacing the affected safety latch with a reinforced component to prevent the flaw.[8] Owners were instructed not to operate the rifles until repaired and to contact Barrett Customer Service for registration via an online form, after which the company provided prepaid shipping labels for return.[8] Modified rifles were returned to owners within about one week, along with an additional magazine as a courtesy.[8] The recall had no reported injuries, though it highlighted a need for rigorous drop-testing in the design of precision bolt-action rifles like the Model 98B.[8] In response, Barrett implemented the modification for all affected units and ceased production of unmodified rifles, enhancing overall quality assurance protocols for subsequent firearms.[8]
