Broken bolt catch, what brand to replace it with

[Great-Kazoo]

The bolt catch on my ar-45 broke today at the range. It looks like a poorly cast part. I didn?t build this lower, so I don?t know who made it. I?ve not paid much attention to the lower parts kits, generally just using palmetto or whatever Numrich has as an add-on when I make an order.

Any strong opinions on which brand to buy when I replace it?

Part of the problem could be the buffer traveling back too far. Have you looked to see if that may be the issue?

That's a darned good thought. I'll check it out.

Thanks for the replies everyone. It's appreciated.

IF the BCG goes noticeably past the bolt release, you'll need to make a spacer, to shorten that distance. I turned down some delrin for my 9mm AR, others use (iirc) 8 quarters to shorten the distance. I like the BCG sitting about .025 behind the bolt release, give or take. Just to keep that bcg from slamming against it on the last round.
