I own many of these magazines in almost all the AR calibers.All function perfect. For the other reviewers that claim to have issues,you have to take into consideration that all ARs are not exactly the same. Therefore, you may have to grind down the edges of the magazine for aproper feed. This is especially true for the 6.8 SPC.

I ordered six of their magazines for my AR-10. They did not function right out of the package so I sent them back to ASC for replacement. It took them nearly a month to exchange the magazines. The new ones they sent also do not function properly. I almost want to give them two stars because the girl that works in their customer service department was very polite and was as helpful as she could be, as well as the fact that they did offer to replace them without any arguing. I can not give them two stars though because of the excessive wait and the fact that I still do not have functioning magazines.

Ive never seen an ASC product that actually worked. Ive had the misfortune to own some of their magazines. When these magazines didnt work I contacted their customer service who claimed that we stand behind our products 100% and that they would be more than happy to replace my non-functioning magazines. In reality, once they got my magazines back they told me that they wouldnt help me at all because the magazines were used! I had to use the magazines to find out that they were defective but discovering the defect voided the warranty? Pretty sleazy. Id never give them another penny, even if their products worked (which they dont).

I bought 10 of the 20 round shorty magazines for my AR15. They all work unbelievably well and I personally love the look of the short magazines. Im hoping to buy more soon.

Bought a five pack of mags had one bad one got in touch with them and they’re taking care of it sent me a new one good customer service

Very good company, great prices, fast shipping!!

Numerous calls and emails garnering no response. Look at the reviews of this dodgy firm on their FB page... Its a mystery how a mismanaged outfit like this one can even stay in business.

Their 9mm Colt mags work great!

No good
