    Not a stock. Ergo, it isn't fold-able. It's a PISTOL not a riffle. Just like getting one of those CAA MCX things for your Glock. It's not a stock.

    I believe we would also use the word - Brace.
    But I know the difference in looks too.

    Question for the JC Arms lower folks. . . .

    I have only shot mine once. But I was futzing with it last night as it has a red-dot I wanted to fiddle with on it.

    There is a S-ton of drag on the BCG. I pulled another upper from another gun and dropped it on the fixed lower - same (although less so) problem.

    The issue is so bad with the pistol upper that I can get the bolt to "stick" 1/2 open.

    Thoughts on a remedy?? Call JC and bring it all in? Simple fix? Is there something wonky with the fixed mag or the bolt release (which doesn't feel quite right)?

    Looking to see if I can remedy this BEFORE calling JC.

    Let me play around with mine but I didn’t have any issues that weren’t related to the mag loader last range day

    Thanks! I'd load the mag with a pile of brass, but I actually don't have any .223 spent brass and I'm not keen on leaving rounds in the gun. I'm just wondering if it's an overly aggressive mag spring. Strange.

    Hmm. I'll have to check that. Maybe pull the buffer from the well-working lower and test it out. I assume I've got a carbeeen buffer in there now.

    i started using a H2 in all my AR's. Had some weird problems with cycling before that.. Heavier buffer and shorter spring eliminated a lot of the issues.

    Might help in your case.. Also might not. But maybe you'll get lucky.
    I also have some old mags that will not work well in one of my guns. So I have them labeled to not use them in certain guns.
    Aren't AR's awesome???

    I appreciate it, Joe. I swapped buffer/spring from another AR. It's grams heavier but it seems to be a lot smoother and won't hang up. Lemme get it to the range one more time and see how she runs.

    Many AR barrels barrels/uppers are over-gassed from the factory. That generally makes it able to shoot a wider variety of rounds. Heavy buffers help tame it a little.

    It sounds like your problem is something other than the buffer being a standard carbine buffer/spring. It could be the stock buffer/spring binding in the tube, or the BCG binding somewhere and the new buffer/spring are strong enough to push the BCG past the binding spot.

    Hmm
