"This mag might be the smoothest-feeding, jam-free magazine ever made, but I'll never be able to tell - it won't even CATCH in my rifle! And it's a new Stag that has no problems with any \"GI-style\" mag I've tried."
"I got a 20 rounder and it works just fine in my bushmaster M4, thanks alot."
"I have one and it never catches the bolt after the last round in my bushmaster M4. If the spring were stronger that would be alot better."
"Doesn't feed in my Olympic M4... sometimes you might get 2 or 3 rounds to go thru but thats about it."
"This mag WILL NOT feed more than the first round in my Swith&Wesson AR /mp-15 Maybee work for you ? Its your money !"

"I BOUGHT 2 FOR MY KEL-TEC PLR 16, AND IT WON'T FEED. I HAVE TWO 30RD MAGS FROM SIG AND HAVEN'T HAD A PROBLEM YET! DO NOT BUY THIS MAG!!"
"I was worried about buying these due to the poor reviews. However, when I read that some of our boys in the Marines were using the 30 round version in Iraq, I decided to take a chance. I'm glad I did. Both magazines I bought feed very smoothly, and so long as I tap it in the way you're supposed to do, it locks properly. The price doesn't hurt"
"Would not fit in my Smith and Wesson M&P 15PC. They seem to be well made(for the money), but I will never know if they function well, because they won't even catch when slapped into my rifle."

"These mags are great, well built, light weight, & feed nicely. ordered to go with my Bushmaster Carbon 15 97S. They seat well and look the part. However, the 20 round mags will not seat in my Stag Arms rifle, 30's fit ok, so be prepared for a possible fit issue."
"These things are garbage. I bought two of them. Neither one of them could load more than a round before jamming."
"Ordered 2 because of the price. When fully loaded the spring tension causes the top of the mag slightly bow out and not securely hold the top round. Every time I went through a full mag the last round refused to strip. Had 1 jam approx. 10 rounds into a full mag. They look nice, but the plastic is not sturdy enough to offset the necessary spring tension to ensure adequate feeding. I tried stretching the spring to increase tension with the hopes of curing the feeding problem, but did not work. Do not recommend purchasing. Have a Bushmaster 20 rd steel mag that feeds flawlessly. -AJ"
"Poor Quality Poly! Poor Design - will not lock in place in my Stag. Pulls right back out. Don't waste your money."
"Bought one at a gun show in January and it wouldn't catch in my Rock River. It took them 3 months to send me a new one and still the same problem. Go with Magpul"
"I ignored earler warnings and bought this because it was cheap and made of polymer (for longevity I assumed). This piece of $%^& Misfed every 3 or 4 rounds. No kidding. PLEASE DO NOT BUY"
"These are a complete waste of time. They wouldn't catch on my S&W M&P 15....they just fall out. You can't even chamber a round. I usually say you get what you pay for....but in this case, I didnt even get a cheap magazine....I got a useless magazine."

"i bought one of these and like it works great locks into my ar and runs great no jams"

"I have a Stag and a Delton, useless in both, no matter what you do it falls out of the mag well. I guess I could 'duck tape' it in, but even when it got held in the well it wouldn't feed. I should have known better, 'Promag' - this is the second time I've got junk with there name on it, there won't be a third."
– Rick in WI
"These are very low grade mags. When trying to use it with a Remington R-15, it would not stay in the mag well. The \"lock in hole\" is filled. I was able to take a drill, and open up the hole which allowed the mag to stay in the well properly. But when testing them out for the first time, one of them would not chamber a round with less than 4 rounds in the mag. I would not buy them again and will probably trash these."
"Jam, Jam, Jam, etc. The mag is now lying at the bottom of a pond, exactly where it belongs!"
