AR mag well issue

[XTAV750]

Ok, so I built this SBR, which so far kicks ass. I'm having one problem that I could use some suggestions solving. I'm using a Troy Ambi mag release and so far my pmags are not dropping free, I have to rip them out to do a mag change. I've loosened the mag catch but it doesn't seem to be helping. Before I look into using a different part, do you guys have any suggestions on solving this issue. It's not a deal breaker, but it would be nice if I could get it to run a little smoother.

Take the mag catch out and see if the mag is binding in the well. It has been my experience that mag pul mags are a little larger than GI.

What mags are you using?

 

[XTAV750]

I'm using older pmags with the window. They drop just fine out of my other ar, so I assumed they'd be ok with the new one. I haven't tried my steel mags since I have them loaded in the safe. I'll give them a try to see it they work any better.

Some lowers have tighter mag wells than others.
Any plastic mag can sometimes bulge a little enough to prevent a free drop.
I'd try some standard aluminum USGI and see if it still does it.

I was using a Troy ambi on my Yankee hill and most of my mags would fall out. Tried everything but for some reason the Troy works better with certain lowers.

That's what you get for using Troy parts .

I know. I'm just a creature of habit. I have one in my oth ar and it it works, so you know... I'll try the gi mags next maybe that'll help. If not I'll look for another Ambi mag release.
