Perform situation: To the 3rd round I get a light hammer strike. I have attempted the two H2 and H3 buffer weights. H2 I was only obtaining a single shot, H3 I now get two shots off. I've tried using this on two uppers, 1 carbine and just one pistol, https://bookmarkpressure.com/story20089131/details-fiction-and-frt-triggers
