Rando09 So weird issue. Ran a GMR cut milspec trigger group in a 20in PSA AR. No issues. Decided to upgrade to the 3.5lb GMR cut cassette trigger. SS goes BRRT no problem. I can drop a D60 in under 4 second (idk actual time) SEMI will only reliably fire when I manually rack one in. Then out of 2x 30 round mags, at most I got 3 rounds off in a row. Most of them are light strikes immediately following the one I manually rack in. After a live fire, I cracked open the AR and the hammer was half cocked. Seems under live fire it'll half cock in semi only. I talked to someone on reddit who suggested I post here for educational purposes. After their comparing cuts it seems like the GMR cut might be too shallow and I'll take a file to it. Also, before I take a file to it, I'd love to get at least 1 or 2 more random online strangers to confirm that it makes sense. Lol. Sorry, I dont have a caliper so this random tape measure is all I got however, it looks like this is cut to 6mm and I probably need at least 7.4mm, so like 1.5 ish off. So basically, Id file 1.5mm off following the yellow here
