HK 91 and clones fixed stock IMPROVED BUFFER SYSTEM

 

HK91, PTR91 , Century C308 standard rifles have a fairly stout felt recoil. I have developed a new piston and spring assembly that reduces the felt recoil up to 30%+. Works on any HK or clone utilizing the the standard assembly pictured below. This is a great addition to collector grade HK-91's, wood stocked, Magpul PRS stocks...etc. This is an alternative where modification to the buttstock is needed for the larger MSG-90 or dual piston G3 heavy buffers.

 

 

Above is the prototype piston installed in a HK standard buffer assembly.  Below in the picture at the top is the improved piston and spring, next is a stock HK stock buffer and spring. The new piston is 2X longer than stock, The spring is about 25% lighter and allows much more piston travel to absorb the recoil.

 

 

 

 

The piston will be made by Rim Country Manufacturing, a leader in US made HK parts. Fixed recoil buffer kit includes a new piston and spring which replaces the internals of your stock buffer. Price runs $45, expect up to a 40% reduction in felt recoil. A complete drop in buffer is available for $59, prices include priority mail shipping.
