Description

HK Improved Buffer System - HK91

Bill Springfield developed a new piston and spring assembly that reduces the felt recoil up to 30% on any HK or clone utilizing the standard assembly. This piston is 2x longer than stock, the spring is about 25% lighter and allows much more piston travel to absorb the recoil. Fixed recoil buffer kit includes a new piston and spring which replaces the internals of your stock buffer.

Please note: the body of the buffer is surplus and the internals are brand new replaced by Bill Springfield. 

Compatible With:

  • HK91
  • PTR91
  • Century C308 (only if it has a HK style backplate only)

    I have a Bill Springfield enhanced buffer, paired with muzzle brake/compensater and a enhanced recoil pad on my Custom built G3 clone. I have about 75% reduction in felt recoil. Excellent buffer .

    I have the magpul prs stock, but the extended heavy buffer doesn't fit without modification. I bought this one, dropped it in with no issues and noticed an improvement in felt recoil. Definitely worth it.
