(2 reviews) Write a Review

ASC AR15 5.56/223 Stainless Steel magazines (Black with Orange Follower, 10-Round) are an improvement on the classic USGI steel mag, with the highest levels of durability and increased longevity

- simply the best in the industry.

ASC magazines are manufactured 100% in the USA using .020 gauge 410 Stainless Steel Alloy and heat-treated for superior strength and lasting endurance. They are chemically treated for corrosion resistance (ref QQ-P-35) and coated with a proprietary finish, Marlube, which is a wear-in not wear-off coating that burnishes into the surface providing it self-lubricating properties. The interior dimensions of OAL 2.316" ra .002 are perfect for any type of 5.56/223 ammunition as well as reloads.

This magazine fits with the following calibers: 5.56x45mm, .223-Remington, 300-Blackout, 5.45x39mm.

Made in USA
