You know anything about ARs ? I built a Psa m4, screwed the easiest thing up!! Put the trigger guard on backwards, pounded a roll pin into a blind hole, the lower was only 49.99 but has the serial # so don't just want to throw away! I was going to just drill thru and push the pin back out the way it went in, don't thin it would cause any issues, just be o hole in the lower where there wasn't, and ideas to get it back out ?
