LOL Yea, I've heard a couple of war stories where folks left bore sighters in the barrel, but never a barrel split from it LOL. Normally they just kiss the 50+ dollar bore sighter good bye.
Only issues I've had, were doubles caused by the trigger not catching the hammer when releasing. My bad...
Fire pin getting torched! Three things it could be; Firing pin to long (nope tested a second one), Bolt out of spec (To short?), It's a Beowulf, and those use Large Pistol primers which in my opinion is not smart. The solution I'm testing on my next range visit is a shortened FP. I really don't want to convert it to Large Rifles cause I would need to rewrite all the load data. I sectioned the brass and there's plenty of meat to deepen the primer pocket - so that might be what I have to do it the shortened FP doesn't work.
What else? I had gotten an AR-10 upper where the FAssist protruded into the upper, but it I remember right those were blems and got for almost half priced. Easy fix though.
I had a couple builds where the bolt catch tang was a little long, causing the top round to pop up because the tang was contacting it when inserting the magazine. To be honest that could be my bad cause I machined the lower from a forged block. None the less it's something to consider during an inspection of a new AR. The fix is to take about .005" off that tang till it works- don't go nuts.
That's about it, and BTW I'll let you know how my DPMS carrier holds up in my Beowulf LOL however I'm using about a 4.375oz buffer made from steel. At one point I had it up to 5.5oz filled with lead but was causing FTF, so I went back down to my original weight using three steel inserts. More weight is not always better!!!
