Hey y’all I’m having an issue with one of my latest AR builds. My bcg continuously short strokes and I can’t seem to figure out why, maybe somebody on here can shed some light on the situation. I’ve tried using numerous brands of ammunition both .223 and 5.56 and nothing is functioning better than others. I’ve put this bcg in 5 of my other functioning rifles and it still short strokes. It’s so bad that It won’t even begin to eject the cartridge. Any ideas that could help me out here??
