Description
This is a replacement HK SP5 recoil buffer for our RCM full auto SP5 (also fits any MP5 pattern gun semi or full auto), removable sear trip carrier or the our modified SP5 carriers. These are lathe turned (NOT 3D printed!) UHMW, high impact, extremely wear resistant Polyethylene. These buffers are mandatory for the SP5 and other full size MP5 pattern receivers with the carrier block plate running an A2 (solid/fixed) stock AND the Magpul SL stock with our full auto carrier. This is a replacement part/spare for our existing customers of our service or modified RCM carrier, required for the MP5 super safety or anyone who wants a slight buffer for their full size MP5 pattern weapon.
IF USED WITH THE HOFFMAN SS, THIS REQUIRES 2 BLUE BUFFERS. AND THE BUFFERS MUST BE MODIFIED BY SIMPLY REMOVING THE INTERNAL NOTCH WITH A 1/2” DRILL BIT.
