Based on the M-4 or AR style the M&P manual
says to use only mags for the m&p. When I was in
the Army we had to qualify with an M-16 but the only
weapons we carried on a tank was a .45 cal. M-3 Grease
gun or sub machine gun and an M1911 .45 So being a tanker
I had little to do with field weapons.

I've noticed lots of talk about the Pmags but couldn't find any
mention of the Cammenga Easy Mags.

My question is this: Will the AR style mags. fit the M&P and
really what I'm looking for the answer to is; Will the Cammenga
easy mags fit the M&P?

Thanks in advance!

Sorry, I don't have any experience with "Cammenga easy mags".

The only issue I've even read about, is that some early M&P15s had issue with pMags? I got a M&P15OR this year and it came with a pMag. The pMags (I've added a few:)) have worked flawlessly.

I also have some of the alum. GI mags with grey enhanced Magpul followers from Bravo Co. Black teflon coated 30 rd for $9.99. These have also worked perfectly in my M&P15.
AR-15 Magazines
I'm amazed one can buy such a quality Mag for about $10.

Most AR15/M16 mags should work fine in your M&P15; but I only have experience with the two above. If no one here can answer (this thread seems to have little traction), you could call Smith and Wesson and see if they know of any issue with those mags.

I was curious, and had to look them up:
Cammenga.com
That's an interesting approach to Mag loading. They look like std 5.56/.223 mags, so they "should work".
 
Thanks a ton CBR. I was begining to wonder if I said a bad
word or something by mentioning Cammenga! I sent Cammenga
an inqiury but have had know response as of yet. There was a plastic mag. that came with my 15. Seemed flimsey but I guess they're tough.......Guess it's a Pmag..
 
I wouldn't classify a PMag as flimsy. However, I've seen lots of AL mags that seem to fit that description.:D
 
The PMags are far and away the most popular AR-15 magazines. They're tough, and they're inexpensive. The easy-mags are a solution looking for a problem. I put all of my ammo on stripper clips and with a Stripula speed loader, I can fill a 30-round magazine in less than 20 seconds.

I also don't bother with the PMags that have the windows in them. The rifle makes a decidedly different sound when the last round is fired, and i don't need to visually verify that the magazine is empty.

I understand. When I got my M&P15 with a pMag. My reaction was, "a #$%& plastic Mag!". I couldn't believe it. From S&W??? Well I immediately ordered some Alum GI mags (those I listed above). But after using the pMag for a few months, I found myself at my local gun shop with a pMag in one hand, and a Alum mag in the other. After crushing confusion, I set down the Alum mag, and started buying more pMags!! I am stunned, but it's true, there are great plastic mags! Who would have thunk it. Between the pMag and my M&P 15-22, I'll always remember 2010 as the year I learned to love plastic.:)

BTW - when I told several friends who are in active service about my plastic Mag incident, they laughed at me and said many of them use pMags, and I needed to get over my "plastic issues":) Not trying to poke fun at the OP, I just thought it was funny, as I was going to the "real guys" so they could reaffirm to me that plastic Mags were bad. That didn't work so well for me.:eek:
 
What I like most about the PMags I use is that you can drop them on concrete and the feed lips don't deform. I've been less successful with aluminum mags when that happens.

Pmags are great for civilian use. I would hesitate to use them extensively in an M4 on full auto, I saw one Pmag cracking toward the rear of the feed lips after only a few months of use. Of course for our AR-15s that is not an issue.

I will suggest a magazine which you may like. The new C Products SCAR magazine designed for SOCOM. It is essentially an updated version of the GI aluminum mag. The body is stainless steel and stiffer, though only a bit heavier than aluminum. They have an anti-tilt follower and self lubricating spring, and come in cool guy tan. I bought a couple recently and really like them. Otherwise good old aluminum GI mags are a great option despite all the new high-tech stuff on the market.

To answer the original question (again!), Any AR magazine will work on an M&P. I run Pmags on mine and I also run the crappy aluminum mags that the army issues, since I have about 30 of them that I have accuired over the years. They both work well.

Pmags are awesome and I love them. I own 7. I got 5 from s&w with my rebate and bought 2 more. I personally wouldn't mind using them in combat. I didn't own mine on my last deployment (2009) but some guys in my company had them and it worked well for them. I don't think they would break shooting "fully automatic", since military M4s are not fully autos, they have only a 3-round-burst option that probably wouldn't damage the mag. You can actually abuse a magazine on semi rapid fire than on burst depending on how much you shoot. Its a matter of taste of course.
 
Thanks for the link CBR240, I will check out those Bravos for $9.99.
I have a few pmags and love them, work flawlessly and I like the clip to protect the feed lips while loaded.

Agree on all counts.

We have M4A1s in SOCOM which have a full automatic selection instead of three round burst. It is hard on the Pmags.

Good deal Sgt V ! That's what I was looking for,
Direction!
I also kinda figured it, but wasn't really really sure
after reading the manual. I didn't want to sink alot of
cash on mags I couldn't use. The easy mags should
be tough as nails according to the video...
 
As mentioned the P-Mag is one of the best mag's you can buy/own for an AR-15. They are WAY more durable then the el' cheapo aluminum GI mags.

I've read several times over the years that the aluminum GI mag's were designed to be light and cheap as they were/are often discarded.

There are video's out there of P-Mag's being run over by 10,000lb+ trucks, then being used to fire full auto.

Plastic's (Polymer) are MUCH stronger then aluminum. The day's of "Plastic" being "cheap" or of lesser quality are long over. Plastic's are the way of the future.

The majority of AR's sold today are shipped with P-Mag(s) from the factory.

OP: As also mentioned above, ANY AR-15 mag *should* work fine in your M&P 15

Pmags are not "WAY" more durable than aluminum GI mags. Aluminum magazines are very rugged and have served well all around the world for decades. I have never seen one fail completely. I have seen cracked Pmags. Pmags are too fat and fail to seat completely sometimes during magazine changes, and some guys avoid them for this reason alone. And I'm not just talking about some Youtube video I saw or webpage I read.

Aluminum magazines were/are discarded? Nope. They are issued and maintained, and any good soldier keeps an eye on his seven+ magazines just like all the rest of his equipment.

I own and use Pmags as well as other magazines of newer design than the aluminum GI. But all of these newer mags are a solution in search of a problem. Anything from an old GI magazine with half the finish worn off to a brand new SCAR magazine will feed your rifle well. Use whatever magazine you feel confident in.

Let me see a 10k+ lb truck run over an aluminum GI mag, then pick it up and fire all the rounds out of it on full auto... (Becides the fact that the mag would be crushed flat and wouldn't be able to even be loaded into the rifle)

I'm not saying a P-Mag or any other mag can't crack or fail. Under normal civilian use, I don't see a P-Mag failing.

You said you've seen a P-Mag crack, but did it fail to work?

You say you've never seen problems with GI mag's, ask your self why there are dozens of different follower's available for GI mags? Could it be because they've had alot of problems over the years with feed problems and follower's sticking?

I've heard some of the origional M&P 15's where P-Mag's would work, but I havent seen or heard of any others and definitly nothing built in recent years where P-Mag's didn't work/fit flawlessly.

GI mag's if fully loaded are hard to seat in any AR with the bolt closed, P-Mag's arn't because a 30 round P-mag can actually hold 32 rounds, leaving room for the rounds to compress in the mag if seated under a closed bolt, where a GI 30 round mag only holds 30 rounds and doesn't have enough additional movement to allow easy seating, you have to slam them pretty hard to seat them under a closed bolt.

So you are telling me in a fire fight, a soldier is going to police his empty mags while he's getting shot at?

..and I didn't say they were purposely discarded, like 1 time use. They were designed to be light weight and cheap and durable-enough.

A solution in search of a problem? What are you talking about!?

Problems with GI Mag's (No specific order)

1. Problem; They are GREY - Who wants a Grey mag on their all black rifle? (Remember, we aren’t talking military use here)

2. Problem; They are painted - No-maintenance is preferred by almost every consumer.

3. Problem; They are clunky - Metal on metal

Those are just 3.

GI mags are cheap, why are the majority of manufactures including P-MAG's now with their AR-15's instead of GI mags? It's not to save them money, P-Mag's cost more!

I'm not saying the GI mags are junk. But they are not the best or only solution for AR mags.

But I have my opinion and you have yours. That's what makes this country great.

I personally prefer my Pmags over my GI. Like stated,I dont want a clunky, light grey mag in my all black rifle. My AR looks like a $2000 rifle with a $3 mag with the GI. And with it not being but a few dollars difference between the two,why not go with the Pmag..
