Edge Report post Posted March 14, 2018 Anyone else experience trouble with the bolt catch on their AR not holding the bolt open? Works fine with an empty magazine but remove the mag or try and open lock the bolt open with anything but an empty magazine and the slightest jar slams the bolt shut.

Hoofnit Report post Posted March 14, 2018 Sloppy fit or wiggle between the upper an lower will cause this, Ive also seen the bolt catch get worn enough to cause it, some parts are not hard enough to last. 1 Share this post Link to post Share on other sites
300RUM Report post Posted March 14, 2018 Have you tried a different magazine? If the spring in the magazine does not have enough tension it may not fully engaged bolt lock. 1 Share this post Link to post Share on other sites

I'm quickly learning there's a huge difference between military and civilian specs. .300 Only occurs with no mag or loaded mag, works as should with empty magazine. AR is new, zero rounds down the tube. If this AR thinks it's a libtard, I'll shred it. Share this post Link to post Share on other sites
300RUM Report post Posted March 15, 2018 I would get together with someone who has another AR. Split both guns in half. Put your upper on their lower and their upper on your lower. Which gun has the problem now? The part causing the failure could be in either the upper or lower. My first guess would be the bolt catch but the bolt assembly is also a possibility. Somebody makes a wedge that installs behind the rear take down pin and takes some of the slop out of a loose upper / lower fit. 1 Share this post Link to post Share on other sites
