Operate challenge: On the 3rd spherical I get a lightweight hammer strike. I've tried each H2 and H3 buffer weights. H2 I had been only acquiring just one shot, H3 I now get two shots off. I have attempted this on two uppers, a person carbine and one particular pistol, https://echobookmarks.com/story20146948/getting-my-rarebreed-triggers-to-work
