Range Use Only, Not for Defensive Use
These are the only plastic magazines I own so am not able to make a relative comparison to something like a p-mag. The magazines work great at the range with my setup, no feed issues, fit properly in magazine well, and fall free when mag release button is pressed. I like the look and style, the grips are good and make it easy to load an unload. I would not recommend these for any defensive purposes, the lips that hold the rounds in the magazine are very fragile and can be damaged easily during loading. If you accidentally hit the lip against the edge of the mag well it is likely they'll break; I've had multiple become damaged in this way. Pros: Capacity Cons: Durability

HIGH QUALITY FROM THERMOLD
A high quality intermediate capacity magazine from Thermold. Great compromise between a 30 round and 10 round magazine that works great for my Keltec PLR-16.

spend money else where
i bought 10 when they were on sale last year, tried them and threw them away. i wanted a short 20 round mag for shooting my rockriver match in the prone position and i thought these might fit the bill. loaded no problem, and shot first mag full no problem. problem showed up when i went to reload and fire again. at this time the top seemed to open up and just let the rounds fall out. it was as if the heat from the chamber caused the top of the mag to deform. i have used magpul for years with no problem as they supposedly have a metal lip to help sturdy the top of the mag and these don't from everything i have read or seen. use these for practice only, never in a life or death time.

What a load of crud. I do
What a load of crud. I dont know how all these 5 star reviews are on here! I bought 2 of these crudtastic mags. Neither will feed and constantly jam, AND the only way to lock them in at all is to have the bolt locked back before you try, no matter how full they are. I have CAA mags and GI aluminum mags and have never had an issue. Save your money!

Not a bad mag, I got 2 of them and have had no issues with either of them. They feed good, hold what they say they will and are good mags. Seems like they should be a little cheaper in price but not too bad of a price. I will buy more of them.

In case you were wonderin
In case you were wondering, Thermold is just another name for Plastic.That said, these magazines are not too bad. After reading some of the negative reviews I decided to put them to the test. At first I loaded each with 10 rounds and had no problems. For some reason some guys said that these were tough to load uFFFD I had no issues. Some guys said that they couldnuFFFDt get 20 rounds in these uFFFD again, I had no problem, except, with 20 rounds they would not lock into my Windham MPC. When I took one round out they locked and loaded just fine. Some guys said that they have sharp edges uFFFD I concur. I noticed this right off but they were not sharp enough to take sandpaper too them so I left them alone.All in all for the money I would say that these work just fine. Unless you have a thing about firing a full box of cartridges in one sitting IuFFFDd say 19 rounds is just fine and, like one guy said, 10 rounds is plenty for one target. IuFFFDm not sure if these plastic magazines will pass the test of time but I have a lot of plastic stuff around the house and, unless you expose it to extreme sunlight over many months, all of it is doing well and I suspect these magazines will last me a good long time.

Great build quality, flaw
Great build quality, flawless feed. I bought two and will buy more. Thirty round mags were too long to shoot with my bipod. Twenty is perfect.

These things work flawlessly, however like others have noted it has SHARP edges, I filed mine down. Just do it very gently you don't want to file too much.

These things work flawlessly, however like others have noted it has SHARP edges, I sanded mine down a little bit because they will nick your finger! Great buy, probably will get more whenever it gets available.

I bought this to serve as a cheap vise block. It performed magnificently. I have not tried to actually use it in my AR.

At the price you can't go bad. They are nice well made USA product that go double the cost retail. They hold full 20 rounds not a bit of trouble fit well in my custom AR rife. Wish I had got double what I bought.

IN SOME STATES THAT ONLY
IN SOME STATES THAT ONLY ALLOW 10 ROUNDS THESE WORK GREAT ONCE CONVERTED. I BOUGHT SEVERAL FROM AN AUCTION SIGHT FOR 20 BONES. CTD CAN'T SHIP 20s TO KALIFORNISTAN. ONCE CONVERTED WITH POP-RIVET OR INTERNAL BLOCKER THEY WORK GREAT AS 10 ROUND. I DID PICK UP 31 RECENTLY AT $4.06. I CAN REBUILD AND MAKE LEGAL. GIVE TO CO-WORKERS AT COST AND WE CAN BE LEGALLY BE ON RANGE ALL DAY. WHEN WE SHOOT ON INDIAN LAND THEN THERES NO HOLDS BARRED. THESE WORK BETTER THAN A DEDICATED 10 ROUNDER OF SAME BRAND, THEY HAVE ENOUGH WEIGHT TO DROP FREE WHEN EMPTY. I HAVE USED SVERAL SET UP AS 10 ROUNDERS WITH. AR FIFTEEN,ATI/OMNI,BUSHMASTER,COLT,CROSSBONES,NEW FRONTIER,OLYMPIC,PALMETTO,ROCK RIVER, AND SPIKES. THEY HAVE WORKED WELL IN ALL OF THE ABOVE FIRED BY ME. 5 BULLETS ARE FOR COST, SHIPPING TO LEGAL AREA,PRODUCT DOES WHAT IT SAYS, I HAVE TESTED SEVERAL. IF YOU LOSE OR BREAK, WHO CARES FOR 4 BUCKS.

I ordered a total of four of these. Two to test the waters, then two after. Granted, these are not 'no tilt' and they probably wouldn't take the desert too well. BUT, that being said, they work extremely well. I'd buy again and again. It's a great product, and for the price, you just can't beat it.

Because of the low price,
Because of the low price, I was very skeptical about the quality. I can report that these magazines work just fine. And they are made in the good old USA, which is probably why.

I bought 5 of these mags
I bought 5 of these mags for my S&W M&P15. I worked them in and out of the gun several times to make sure the would fit. I noticed plastic shavings coming off as I did. I then loaded each one with 10 rounds, went to the range, and had NO PROBLEMS. I would 'break' them in before loading them with 20 rounds. I did load several with 20 rounds and some would 'spit' the last round out. So, I just backed them down to 15. That still gives me 75 rounds. I like them best for sighting in. You can't get a 30 round mag and gun in a gun rest. The ONLY disadvantage I had was they will not always drop out of the gun if you try to quickly change them. That is because they are light and tight, but they may get better with more break in.

I have now put a few hundred rounds through the pair of these mags I got when I built my AR. I figured for the price, why not? Well I haven't had a single failure yet, and they work just as well as the PMAGs I also use. I actually keep one of these mags loaded, and wouldn't hesitate to grab it in a self defense scenario. If I start having problems, I'll be back here to change this review, but as of now, I see no reason to not buy these.

Price was so good, I boug
Price was so good, I bought a bunch of these sight unseen. Regretted it afterwards, until I took them out to the range. Now I'm a believer. No problems inserting in the magazine well of my M&P15. No fail to feed. No stray rounds jumping out when fully loaded. Corners are sharp on the base of the magazine, but can be rounded off with a bit of sanding. Would have given it 5 bullets, except for the last comment.

I purchased 2 of these for my Bushmaster AR-15 because the price was attractive. Save your money, folks. To put it gently I would NOT purchase these mags again. As stated these are made of plastic. As I began loading my rounds the mag started to bow and bulge. After about 5 or 6 rounds, the top couple rounds would begin to spit out. When I was finally able to load 19 (definitely not 20), I could hear the rounds rattling around inside as I gently shook the mag. If I shook with any force, once again the top couple rounds would eject. I tried Winchester 5.56, Federal .223, and Remington .223 frangibles which were definitely an epic fail. If I was heading to the range and I had nothing else to use I would consider these. As for tactical or defensive situations, not a chance! I hoped this helps. Maybe you'll have better luck. Happy Shooting!

For this price, you can't
For this price, you can't go wrong. I've had some problems with rounds wanting to jump out when loading, but they're easily comparable to GI mags, capacity aside. Durable. Functional.

I bought 3 of these to us
I bought 3 of these to use on my M&P15 while shooting prone or on a bench rest and they work great. Would have given 5 stars, but man are they sharp around the edges. I cut my finger pulling one out of the range bag. But as far as function and dropping free, they work great.

It gets 5 bullets only because of the price. They worked great, but one had a double feed and jammed in my AR. Also the LRBHO didn't activate 90% of the time. The other problem is that every once in a while the top round would randomly pop out. I suggest you pick up a few, but spend the rest of your money on real quality mags.

I got this and used it this past Saturday. I wasn't expecting much, honestly didn't expect it to feed. But boy was I presently surprised. Very well built, and fed 100 rounds with no problem. I only put 10 rounds in each mag for training, any more would be a waste. These worked out great. And great when in prone. gonna order several more. If your gonna give it a try, then make sure you grab at least a couple. you will wish you did if you dont.

I've owned my Rock River
I've owned my Rock River Arms entry carbine for two weeks now and this is the 4th magazine I've bought. It is also my favorite mag. The only cons is it has is the front corners on the bottom are kind of sharp, but thats no biggie. Like most plastic type mags I've tried they are hard to click into the magwell if it's completely full (if it has 19 in it, it works perfectly). I also have a 30 round plastic Tapco mag that I like almost as much as this, but I just do not like 30 round mags at all. I like the straight 20 or 10 rounders (the long 30 rounders just get in the way when my bipod is set on the lowest setting, plus curved mags just look stupid to me). Kinda ironic that this is the best mag I own or have used and it's half the price of my next cheapest mag. Buy this magazine. They work awesome!
