I bought 2 of these for an AR platform Keltec, both jammed immediately, further investigation revealed the springs tied in knots inside the mags, don't waste your money on these, a deal isn't a deal if it doesn't function!

I bought 5 of these magazines and every one double fed or jammed in my gun. I tried my bush master and several different magazine and and they worked fine. Becareful, the bullets all were jammed back into the shell casing.

Bought 2 of them, loaded 1 up with 30 rounds, and jammed after 2nd round. Couldn't get 1 shot off without having to reset the clip or free a jammed round. Then the spring broke. Complete waste of money. Hopefully I can get my money back.

Bought a Bushmaster M17 bullpup a few years ago and found it to be a picky eater. I bought a few of these mags and when first seating them into the mag well, they fell right out. A little testing and then a little filing with a Dremmel and I could seat them. You get what you pay for on these mags. Good "entry level" stuff and no jams thus far. I have a DS Arms DSZ-M4 rifle coming soon and will see if the redone mags feed it.

there not tobad i guess dont really have a feed prob, but if u smak it up in the mag well hard it will jam the rifle, but if u just seat lightly shuldent have a prob, but i think ill stick ti buyin polymer mags tougher and lighter

i bought one of these mags for my DPMS when i used it it would jam round after round and IF you make it to the last round the bolt will lock back before it puts the round in o and they rust very easy.

dont waiste ur money i'm sorry i did!! bought six, loaded two w/20 rds each, springs broke. i didnt bother trying to load the others.

I bought 4 of these and plan on buying more. They seem to load and feed better than more expenseive ones. After reading other views here, I musta got lucky and I will try again until I see other wise.

If you want a great magazine these are the perfect blued steel bodies. I got them just for the body and then added a Magpul kit containing the ranger floor plate, spring and anti-tilt follower. It made a perfect magazine, cheaper and better than the expensive H&K AR-15 Magazines.

I purchased several of these magazines for my DPMS. Not a one worked properly. They double feed, jammed etc. I threw them away and bought the good ones. Don't waste your money.

Dont bother with these mags. In my Bushmaster, the mags stick and dont fall freely, and have to be tugged hard to remove them. They also double feed or completely fail to feed. It is worth the extra couple bucks to get original manufacturer or USGI/military contract mags.

I see that there are different manufacturers for these mags so it's a crap shoot. I ordered three mags as I saw differing reviews and figured I would roll the dice. Mine were made by Colt. I'm pretty happy so far, they seem like good mags to me. Now I wish I had ordered more.

Dont dare spend a dime on these magz! I recently purchased 3 of these mags, each double jammed every round attempted! Yes, these were that bad! Each of the 3 magz jammed every load. I picked up 3 new GI mags never had a jam since, dont buy these... only if you are purosely attempting for training purposes on clearing jams.. these are THAT bad.

I ordered several of these for me and a friend, and they tend to jam and double feed most of the time. He has a new Bushmaster, and he can't fire more than a couple of rounds before it jams. I have an Oly and a DR200, they won't feed at at in my Oly. My DR is a little more forgiving but I can't fire more than a couple of rounds without having to clear a jam.

Not bad, was what it said, I put two mag fulls through my HSA-15 M4 with no problem at all.

The first time the last bullet didnt feed right and it stayed in the mag and the 2nd time it shot perfectly, i did not have the problem of tight fitting that the last person had, but there arent any markings so they may have come from different places? i will get more and see how those work

Shotty spot-welds on uneven seems although magazine body itself never proved to be a problem. The problem is the flowers. I purchased several of these mags and over half of them have feed problems. In the ones with the failures the flower constantly tilted to an angle inside the magazine causing the rounds not to snap into proper placement at the top of the ammo stack. Often times the first few rounds were tilted at a downward angle because of which when the bolt attempted to feed a round it would push the round into the front edge of the magazine instead of into the chamber. This actually caused the bullet to be shoved back into the case while the entire round stayed in the magazine. As I said before this happened multiple times with multiple mags. If you are looking for reliable magazines DO NOT BUY this product.

I bought two of these for my bushmaster. One came bent and it actually fed better than the other. Both caused jams. Even for the price i wouldn't recommend this product. Your better off spending more money on brand name.

Feed great, never a jam, fired 100 round of Full Metal Jacket, and Hollow Point Ammo mixed every fourth round in this 30-rd magazine, ate the whole thing without a burp. I highly recommend. Outstanding!!-Hooyah!!!

If you like steel, this is the one. Cheaper than anywhere else that I've looked, and functions perfectly.
