$265.00

Reduction of recoil is accomplished due to the patented multiply springs & counterweights mechanism. The system produces advanced recoil reduction by gradually slowing down the bolt carrier before stopping in the bottom the tube. Included also two extra buffer springs, two counterweight springs and an extra heavier counterweight. The shooters can fine tune the rifle circle and the recoil and further to secure the correct bolt locking.
