Bill Springfield HK 91 Improved Buffer System

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)
