Could not trust
The magazine's I got only held 39 rounds. And at that with absolutely no give. So a 38 round magazine. I also had a hard time extracting the rounds. The tips kept catching. I never used it because I could not trust it.

Disappointed
Worked well the only time I tried it. But I keep it loaded and all of a sudden it won't hold any ammo. They just pop out and spill all over the place. I really wanted it to work well. I like the extra ammo and it feels solid for being plastic.

Won't feed properly
Loaded mag and got 1 shot off then experienced a misfeed. Reset gun and made another attempt and only shot 2 rounds before misfeed. I have tried 'tamping' loaded mag on the end , pulling rounds off and reloading mag but still getting misfeeds after 1 or 2 rounds. My Magpul work whereas this did not .

This is an awesome one
My wife got me a few of these as a Christmas gift and I have to say they are awesome. A lot of people have negative reviews but out of the few I have all are equally as good. I would recommend buying these if it's legal for you because how good they are and you can't beat that price. Thanks cheaper than dirt, always coming through. Also people say not to over load magazine but I have found I can load one or two more with out any failures or dangers to my gun. So it's really 42-45 round mag! Pros: Feeds well Cons: Hard to use with a bipod

Extra rounds without breaking the bank... highly recommend!
I first used this mag on the range and it operates flawlessly, very easy to load without the use of any speed loader. The best part is the price point 42 rounds for $13.95 or 50 rounds for about $72 it's obvious which to choose unless you like throwing money away. But nevertheless it's still $7 cheaper than the $19.95 magpul 40 round version in short awesome mag! Pros: Durable Cons: Too long for vertical grip with bipod

Seems solid so far
Haven't actually shot with it yet but seems solid some people said holds 45 or more got 43 in but to not mess up the spring I'll just put 42 in but fits good in my AR bought this for a defense mag need to test it before it's used as one though have a good feeling it'll work fine bought a 15 round pro mag to use whenever I use my foregrip/bipod 30 round Magpul ones were to tall and it works great so all round happy with it if for some stupid reason I go to use it and it falls apart or something will update

I would not buy this again
I used it once, I understand there's duds every now and then, but come on. I couldn't get more than 40 in there, no biggie, I figured it would break in. My AR has never malfunctioned over 1,000 rds in it so far. Anyways I shot about 17 rds out of this magazine and I had a malfunction. The round kinda got jammed somehow, short story long, I pulled out the mag to clear the rifle. So after inspecting the mag it felt like the spring gave way. Like it was stuck down or non existent. I manually unloaded about 7rds and then about 15 fell out like I was shaking a box of tic tacs upside down. I banged on it a little and it felt like the spring relieved a little but, it'll go out in the trash if they won't refund/ return it. Pros: Price Cons: Doesn't Work

Clumsy
Thought this magazine would fit in well with my thirty round magazines but I found that you can't use it while sitting at a shooting table or prone because it is just to tall. So sure you don't lead as often but because of it's height your shooting options are limited.

Poorly Made
For all the hype the manufacturer does about their product, it sure was cheaply made and out of specs. The magazine catch that holds the magazine in place was not deep enough to hold magazine in the well. Haven't bothered contacting manufacturer because I am sure they will just blame the rifle. Once again money down the drain.

The only way these magazi
The only way these magazines could have been better is if they were made of metal. For the price difference it was not worth it for me to spend the additional money. They load fine, they shoot fine, and I have not had a jam yet. In my opinion these are a must buy! I have been buying from pro mags for a few years now and have them for multiple guns in multiple quantities and love everyone of them! Don't hesitate by as many as you could afford before the government takes them away!

These mags work just fine for my Bushmaster ORC. I had to do minor filing to make exit ramps a bit smoother. Fills all the way to 42 rounds, no problem. You may have an issue with initial feeding if you don't charge before inserting the clip. Definitely good product, 4 solid bullets. Saves a lot of time on the range!

Bought two, loaded to capacity. Both first 5 rounds jam. Empty them and inspect next to Magpul mag. both were poorly machined at the top. Bits of plastic and lips where they were bot meant to be. I took out my knife and whittled the plastic to match the Magpul. Worked for the rest of the day. Suggestion(when you buy these take a file to them and make them match the mags you trust. It'll save a headache. They work fine now but wouldn't trust my life to them.

I have 2 of these and so far have not given me any issues. The hold the bolt open on empty and drop free. They are a bit stiff at first, so they are kinda hard to insert when fully loaded on a closed bolt. But they have loosened up and have worked reliably for me. For less than 15 bucks they are worth it. I wouldn't pay more than that for them. Only because they do not seem to be as tough as other polymer mags. That is the only thing I do not like about them. One of mine has a crack on the feed lips that it got when it dropped free and bounced off the shooting bench from a height of about 4 feet.

I have now gone through three of these things, i wrote a review about the first one i bought, it had a broken feed lip. I bought two more in hopes that the first was a dud, the other two did the exact same thing, the feed lips cracked under pressure from being loaded and left to sit for a month, i only loaded them with 40 rounds and put them on a shelf in my closet for a month, i then took them out and they had cracked from sitting there. Not that it matters any more anyway, but IF these do not get banned then i would suggest buying something else.

I bought one of these magazines to see if I should buy more. I will buy one more in hopes that the first was a dud. The one that I got was nice looking and was able to load it without problem. I only put 40 rounds in it and left it like that for about a month and a half. I went to use it at the range a couple days ago and when I picked it up, a few rounds shot out of it and the left feed lip had split and allowed the rounds to pop out. Not sure why this happened but it did. It just sat in my closest and I didn't drop it or anything like that. So maybe it was sent to me with the problem? But I will give another chance. I will do the same thing though: load 40 rounds and let it sit for a month and see what happens. I want them to work, so fingers crossed.
