Thanks for the replies, I talked to my buddy who is a machinist and helped with making the lower, of the 20 some guys who ordered and cut the lowers nobody got a screw in pin, which is at the start worrisome as I don't know how often it would need replaced! The pin is tight I tapped it in with small hammer, I'll try the utility knife if not prolly going to use Dremel and try to cut the pin on 1 side. I did however find another issue with it as well, had it cerakoted and put in a pmag and it is a REALLY tight fit, mag has to be pulled out somewhat hard, so now on top of first issue I have this too. Might try taking back to shop who did coating and has a gunsmith on site and see what the can do. Worst case scenario I have to order a new lower and bolt catch! Sent from my iPad using Tapatalk
