Walther LGR
The Walther LGR air rifle was developed by the German arms manufacturer Carl Walther GmbH Sportwaffen as a high end match rifle for 10 metre air rifle competition shooting. The LGR was the first match air rifle that employed the then futuristic single-stroke pneumatic method as power source. This use of pre compressed air introduced the advantages of recoilless and vibration free shooting in combination with a well-made air rifle into the sport. It took other manufacturers a decade before they also introduced single-stroke pneumatic match air rifles.
After a long development period the Walther LGR emerged as the main rival of the successful Feinwerkbau 300(S) match air rifle series, that were powered by a spring-piston coupled with an ingenious recoil absorbing system that allowed the barrel and receiver to slide back and forth on a rail system. The complex Feinwerkbau 300(S) design had up to that moment dominated the 10 metre air rifle shooting sport.
Immediately after its introduction in 1972 the LGR broke the individual and team 10 metre air rifle world records. This record breaking made the international shooting union, known as the UIT back then, but today the International Shooting Sport Federation (ISSF), decide to reduce the size of the 10 metre air rifle target to its current dimensions.
Other match air rifle manufacturers reacted to the introduction of the Walther LGR by further refinement of spring piston rifles. These late spring piston era match air rifles, the Anschutz LG 380 and the Diana Model 75, were certainly of high quality and very accurate, but spring piston technology, with its complex recoil cancellation mechanisms and slow lock times, was no longer cutting edge. The competition successes of the Walther LGR forced the other match air rifle manufacturers to ultimately drop the spring-piston-powered match air rifles and move into the “recoil free” pneumatic era.
The Walther LGR kept on dominating match air rifle shooting and held many records until the introduction of the Feinwerkbau 600 series single-stroke pneumatic air rifles in 1984. The Feinwerkbau 600 was easier to cock than the Walther LGR, lessening shooter fatigue over a 60 shot match and had an even faster lock time. The LGR's successor made by Walther was the LG90 single-stroke pneumatic air rifle.
The LGR system is a purpose-designed high end match air rifle, rather than an accurised version of an existing, general-purpose air rifle. As such the LGR stocks and systems were offered in right and left versions.
The LGR shoots virtually recoilless and vibration free, since only a few small trigger parts, a light striker piece and lever that open a small air valve in a compression chamber and the 4.5 mm (0.177 in) air gun pellet move in the rifle during shooting. This minimal movement and balance shifts coupled to a fast lock time favour the practical accuracy capability and made the LGR superior to previous match air rifle designs. As in any air gun the air seals wear during use and have to be replaced when leaks occur.
The heart of the TRG system is its receiver that houses a single stroke pneumatic power system that is operated by the users muscle power with a side-mounted cocking lever. While the cocking lever is pulled back a constant volume of surrounding air rushes through air intake holes into the cylinder. During this operation the trigger is also cocked. On pushing the cocking lever back forward the air is compressed by a piston to a constant much smaller volume in a compression chamber. This results in an operating pressure of about 60 to 70 bar or in SI units 6 to 7 MPa (870 to 1,015 psi). The hinge mechanism that connects the cocking lever to the air cylinder piston protrudes out of the rifle at the rear of the air cylinder under the back sight. The lever sports a large synthetic bulbous knob that provides a firm grip when cocking the rifle. The early LGR rifles had a reputation under smaller framed persons for being physically strenuous to cock during extended training and match sessions compared to the Feinwerkbau 300 match air rifles. This problem was addressed by improving the cocking system, though the improved Walther LGR still required more effort to cock compared to the Feinwerkbau 300 series.
