Any good 40rd ar-15 mags?

Most of them suck, but the Tripp has been solid for me.

That said, it is essentially a specialty piece of gear that is, admittedly, not completely essential. I don't run it at every match, but will pull it out of the range bag if it seems like it would be useful. For a rifle or 3Gun match, I'll typically take a single 40 round magazine, two or three 30 rounders, and a pair of 20's. The result is that I have more flexibility in how I can approach a stage.
 
I just about always run 30's, good USGI's or PMAGs. I have a Nordic/PMAG 45 (?) round mag or two, and a bunch of PMAG 20's. I never end up using them. If the barricade is low enough I would need a 20, I'll just do a 45* angle or rollover prone.
 
I think the photo in post #42 is what I was referring to as to hard to get prone.

I think where some of the differences of opinion come from, may be whether you are talking about three gun matches, or trying to get very very low if someone is shooting back at you.

As I recall it was sometime in the early eighties when we were issued thirty round magazines. I really liked them until I shot prone and realized that I had to stick my head up to do it.
 
I would rather have two 20 round mags then one 40 round for any day, place, or use.

Even a 30 round sticks down too far a lot of times.
I agree and use 20 rounders almost exclusively. I keep a few 30s; but ammo comes in 20rnd boxes, it weighs less, it gets in the way less, and is easy to use from prone.

The only magazine that I have heard good results from and is somewhat reasonably priced is the Sterling magazines designed for the AR-18. These have the AR-18 slot (due to the different mag catch design), but they also have the standard one for the AR-15 as well. These are fairly rare (only made for the Sterling AR-18s), so I would scour GunBroker, gun shows, and the internet to see what I could find. I have not used one and honestly don't care to due to the unwieldiness, but if you like it go for it.

:)
 
Wow thanks guys, all the info is great. Well I can tell you guys I dont plan to go out and buy these guns for just three gun shoots...they are already on my list of guns to buy. Im not sure if I would want to be in open class, im gonna have to start watchin 3 gun shoots to know how things work. I guess im just gonna have to get the 590 I want and get good at loading on the go.
 
I just had a thought, they make things to block the mag release for california ak type guns right? Well if I where to have one of those and a 20rd drum on a saiga would that take it out of open because it no longer uses detachable mags or any other kind of speed loading device?
 
The capacity is certainly an issue, however, even with a downloaded gun the Saiga would still have an advantage over a more traditional shotgun because they're much, much faster to reload.
 
Well how about with an 8rd clip, I wasnt sure if there was a rule on the capacity I just heard about there being one on the clips becuase its consider a speed reloader
 
Yeah, that's the thing. To reload a Saiga, all you do is change magazines, which takes about two seconds. To reload a more traditional shotgun, you have to stuff the shells in the tube one at a time. I'm not terribly fast at it, but it takes me around four seconds to load four shells.

The disparity in mag-change times is enough of a game-changer to be something that it would outpace the use of the more traditional tube-fed guns, which is presumably one of the reasons they're mostly relegated to Open Class.

The original poster was asking about the magazines in the context of shooting 3Gun.

I've never been in the military, let alone been in any sort of combat, so I'm frankly not qualified to comment on the utility of such magazines under combat conditions.
 
Justin,

Here's the OP.

Any good 40rd ar-15 mags?

--------------------------------------------------------------------------------

Like the title asks I was wondering if there are any good 40rd ar-15 mags? I seen some at a gun show and they seem to be decent quality and almost got one but passed. They had anti-tilt followers.


I didn't understand that he was talking about three gun matches, so I put it in the context of my own experiences, and was just responding to the usefulness of 40 rnd mags.
 
Ah, my bad. He didn't state it off the bat, but later on in the thread:

Thanks guys, well at first I will be using it for fun, but I would like to get into three gun shoots within the next year or so...

I should have gone back and verified his posts.

Other than the larger dimensions meaning that the magazine will not fit comfortably in your mag pouches on your rattle, there is really no concern. If you only carried one, and that was the one in your rifle, carry on.
 
Agreed. I've tried running the big magazine in a Blade-Tech mag pouch, and it doesn't work well due to the weight of the magazine. After trying that a couple of times, I switched to using the magazine only if it's convenient to start the stage that way.
 
Only way I could see it working would be with an AK-type pouch and an AR mag. But I haven't tried it, so I couldn't really say with any certainty...but I wouldn't want to carry one in a pouch on my rattle...been there, done that, t-shirt's in the laundry bag.
