ASC 458-SOCOM/450-Bushmaster Stainless Steel magazines (Black with Black Follower, 5-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" ± .002 are perfect for any type of 458-SOCOM/450-Bushmaster ammunition as well as reloads.
