AR Mag Compatability Question

[CA Marine]

Since I will be taking possession of my S&W M&P15 really soon I have a couple questions regarding AR mags. First off, what is a good CA legal 10 round mag that is primarily used here for AR's?

Second, are all AR mags universal for the most part? For example, (and yes I know I'm not suppose to do this) will my M16 M4 Carbine 30 round magazines fit into my S&W M&P15 and function with no issues or is a S&W very restrictive to what magazines can be used in them? If so, what magazines work well with the S&W? Just curious.

Yes, universal. Some rifles that use the AR type magazine system may not fit all types and varieties of AR mags. For example, the FS2000 from FN does not really work with the first gen. PMAG.

we have 3 types of 10 round magazines that will work well with any AR, including your S&W:







the only difference is which one you like the look of. they are all 10 rounders and CA legal in a maglocked AR.

Thank you Pacrimguru! The look I like to go with is keeping the AR close to the size of the 30 round mag. I just don't think they look right with those "shortened" 10 round mags. It doesn't fit the look of what the rifle was intended in my opinion.

I would definitly go with either the first or the second style you posted. I can't tell by the pic's, which one is closest to the normal "30" round mag size? The first or the second one?

The first one is the 10/30 (30rd blocked to 10rd) and the second one is the 10/20 (20rd blocked to 10rd).

The first one is the 10/30 (30rd blocked to 10rd) and the second one is the 10/20 (20rd blocked to 10rd).

Roger that, thanks!

you're welcome and yes, the first one is the standard length, "30 round" style mag but are 10 round CA legal. go ahead and click on the pics, they are linked to item descriptions.

i have the exact same rifle. i've had no problems with the pmags, cproducts, and a few other brands i forget the name of. i haven't had a AR magazine not fit the M&P 15 yet. However i did read somewhere that the magul pmags have some trouble fitting. the ones i have actualyl have the smith & wesson log and M&P 15 stamped on their as well. so just might wanna keep that in mind. and if you decide to go with pmags try to get the ones with the S&W M&P15 marked on them and you should have no problem

Thanks for the info Eric! I will check these out as well!

I got my m&p 15 a couple months back and all of my pmags worked with it no issues or any filing.

As others have said the M&P works fine with CProducts and 10/20 and 10/30 blocked PMAGS. Personally I prefer the PMAG 10/20 for bench and prone shooting. You can't go wrong with Magpul, and several vendors here sell them ready-to-go at a decent price.
