Title: AR extraction question
Post by: Rob on October 14, 2015, 08:16:52 AM: I have noticed form time to time on a couple of my home-built AR's that I have difficulty extracting a loaded round.

Here is a description of what I am doing:
-I load a round in the mag
-I pull the charging handle all the way back and the bolt carrier group is released so that it pops forward quickly - as designed
-The round chambers fine, and if I were to have pulled the trigger, it would have gone off, ejected and loaded a second round without issue
-However, if I decide to unload without firing, the Charging handle is nearly impossible to pull back. I can do it, but it is really locked in place firmly.

I always check my chambers with go/nogo gauges and they have all passed. No signs of pressure on fired brass.

Anyone else ever have this problem or knows what causes it?

If the problem is with store bought ammo, then I am not sure what the issue is.

Buffer spring bound up? Locking lugs clean/ damaged? Ive seen lots of reasons this happens, would need my grubby hands on it to find the fix.

I think you nailed it Seth. Thanks for the tip!
