Description The R-410 G3 Stock Assembly brings the venerable HK G3 platform into the 22nd century, providing it with better handling and recoil management. Using the factory end cap, the 6-position adjustable stock is fully adjustable for length, with a length-of-pull of 320-400 mm (12.59”-15.75”) and has a non-reciprocating cheek piece (additional heights available) which positions the shooter’s eye in line with optical sights. Thanks to the enhanced ergonomics of the stock assembly, recoil management is greatly improved, providing for fast accurate fire. Ships with R-416 cheek piece (as depicted). Additional Cheek Piece Risers can be ordered separately. Will fit HK G3 and Umarex VFC G3 GBB, as well as the CETME, HK MP5, HK33, and HK53 provided the firearm has a metal back plate for a fixed stock.
