Alright. After all the hell to remove a barell w/comp, and installing a new barell, the delta shot great. 200 rounds of 155 jhp. groups were sub 2 inchs at 25 feet. my question is, i am running a full length guide rod, 20 lb spring, and a shock buff. It chewed the shock buff all to hell. What is the recoil/guide rod set up you all suggest to preserve the frame (i dont want it cracking on me).
