MP5/HK33/53 Stock Assy, Low

The R-315 MP5 Stock Assembly offers the proven design of the R-310 MP5 Stock Assembly but with a quick detachable cheek piece - allowing for the use of the factory iron sights.

Using a stock adapter machined from solid billet aircraft aluminum with an integrated buffer, the 6-position adjustable stock is fully adjustable for length and has a non-reciprocating cheek piece (additional heights available) which positions the shooter’s eye in line with optic sights.

Thanks to the enhanced ergonomics of the stock assembly, recoil management is greatly improved, providing for fast accurate fire even when shooting fully automatic fire.
Will fit HK MP5, HK33, and HK53 (and clones).
