MP5 Upgrades

The HK roller-delayed series of firearms has long been criticized for overly long stocks, which pose challenges for shorter users and those wearing body armor. 

To address this issue, we developed a 6-position stock assembly with replaceable cheek pieces, accommodating various sighting solutions:

R-315 MP5/HK33/53 Stock Assembly, Low
This adjustable stock allows the length to be customized between 180-260 mm (7.09"-10.24") and enables the cheek piece and butt plate to be raised by approximately 20 mm (0.8").

These adjustments ensure the Length of Pull (LOP 290-370 mm/11.42-14.57") can be tailored to the users clothing or physique, making the firearm more controllable and optimized for individual operators. 

R-301 MP5 Forend (NSN 1005-22-630-0395)
The R-301 MP5 Forend is a lightweight, modular solution designed with the same principles as our G3 forend. It provides improved functionality while maintaining a streamlined and ergonomic design. The R-301 is also compatible with the HK53. 

R-302 MP5 Top Rail (NSN 1055-22-630-0396)
The R-302 MP5 To Rail enables users to mount optics on the MP5, providing enhanced functionality. Like our G36 and HK417 forends, the rail features a smooth design for improved handling and excellent repeatability. 

We also offer a variety of top rails, including options with direct mounts for Aimpoint Micro and standard Picatinny rails. For more details, please contact your designated point of contact.
