Perform difficulty: Over the 3rd round I get a light hammer strike. I've tried both H2 and H3 buffer weights. H2 I used to be only finding one shot, H3 I now get two photographs off. I've tried out this on two uppers, a person carbine and a person pistol, https://beaudwncr.bimmwiki.com/11164455/fascination_about_rare_breed_trigger
