ASC manufactures an American classic that transcends the industry standard with the use of cutting edge robotic manufacturing technology and our commitment to construct our magazines with only the highest quality materials. Our lightweight aluminum magazines are manufactured 100% start to finish in the USA using 6061 T0 grade aluminum, heat treated to a condition of T6, and hard coat anodized per MIL-A-8625 Type III class I for ultimate longevity.  

We offer a variety of durable coating options that will suit your needs. We have our proprietary coating, a high grade Marlube in Black or FDE which is a wear-in, not wear-off, coating that burnishes in the surface providing self-lubricating properties, a hard-coat anodized grey with Teflon® impregnation providing a non-marring, sleek, uniform finish, and finally the mil spec dry film grey coating. 

Your number 1 choice for reliability, durability and superiority!

Misleading Photo
Jeffrey Parker (Peoria, AZ) 12/24/2018 5:18 PM
Ordered 4 of these by mistake... my fault for being in a hurry and not reading the description. The photo looks like a 30. These are straight body 20 rnds. Also the follower is orange, not green. Aside from my error, I am very impressed with the quality! They look identical to what we were issued in the military decades ago. Except for the brite orange follower, which I prefer. I’ll end up using them for bench or prone shooting so it worked out in the end. I’ll just order more 30s. Excellent price for high quality mags! Shipped same day. Arrived fast too.
A Good Solid "Retro" 20-Rounder

I can't complain about these mags. They do what they are supposed to do. I like 20's for shooting from the bench and competition because 30's can be too long, especially if you are shooting prone. I do have trouble with them falling free in some Anderson lowers, but not all.
