Great heavy buffer! - Tactical Superiority H5 Buffer for BlowBack Gas Systems Only or w/8" Buffer Tube

I built a Aero EPC 9 with a PSA upper. The recoil was fairly sharper than expected. I used the H3 buffer and stock 308 spring that came with the original buffer system purchased. I then upgraded the buffer to this product and a Sprinco Orange Spring. That combo has significantly lowered the recoil and has helped to smooth out the action of the gun. I would highly recommend this product if you are using a straight blowback system.
