    AR Magazines

    So I'm new to the AR scene and I was watching "American Guardian" or "Best Defense" and they mentioned "only having 28 or 29 rounds in each magazine." Are they referring to inserting a full mag and chambering a round thereby leaving you with 29 or is there some reason to not load a mag to full capacity, chamber a round, and then top off the mag? Thanks!

    Downloading a 30 rd mag to 28 rounds will allow you to more reliably seat a fresh mag in the rifle with the bolt closed (like when doing a "tactical" reload).

    Having your fresh mag fall out of the rifle on the next shot is no bueno.

    That makes sense. Still be a good idea to train to tug after each mag insert though. Thanks!

    It is also a non-issue with PMAG's. The reason an aluminum mag will not seat properly on a closed bolt is because the magazine is loaded to max capacityand the round is actually hitting the bottom on the BCG. Magpul has apparently calculated that into their design.

    Glad I bought PMag's then! Only aluminum mags I have are the factory ones that came with it.

    Even with 30 rounds and Magpul followers in Aluminum mags, I still have around a 1/4" inch depth left when I push down on a fully loaded mag. As always, use "push pull" when inserting a mag, and use what ever you feel comfortable with (28 or 30 rounds).

    I own strictly GI mags, have a pretty good supply on hand, and have yet to purchase a Magpul Pmag. But, I have been considering purchasing a few Magpul followers to try out.

    Regardless of make, test them. I've seen Pmags that didn't work that way.

    It's always good to have a healthy mix of usgi mags and pmags. I put magpul followers in the usgi mags so they can run better.

    All my Pmags will take 31 rounds easily, and if I remember correctly, that's a side-effect of being designed to function better with 30 rounds than a standard USGI aluminum mag.

    That said, at class last week Costa recommended 28 rds in mags across the board, including Pmags. I did so, and it worked. I had a couple times that the mag was still hard to seat... Could have been other factors (or accidentally loaded to 30).
