This ASC 15-round magazine for 6.5 Grendel AR-platform rifles is built from the ground up with quality materials and proven design. Manufactured entirely in the USA using .020 gauge 410 stainless steel alloy, the magazine is heat-treated for superior strength and endurance. The construction means you don't have to worry about your magazine warping in hot conditions or becoming brittle when exposed to cold weather, something that can happen with polymer magazines.
The stainless steel body is finished with ASC's proprietary Marlube coating, a wear-in finish that burnishes into the surface and provides self-lubricating properties. The magazine features a blue polymer follower with anti-tilt design and chrome silicon springs inside. All of this comes together to feed reliably whether you're doing precision work on the range or working with handloads.
At 15 rounds, this magazine strikes a balanced middle ground for 6.5 Grendel users. The interior dimensions measure 2.316" in overall length, which is precisely sized for the Grendel cartridge and makes these magazines ideal if you reload. The 300-series stainless steel floor plate is easy to remove for cleaning and won't corrode. It also comes backed by ASC's limited lifetime warranty.
Yes, this magazine is compatible with both 6.5 Grendel and 6mm ARC ammunition. The interior dimensions are sized to handle both cartridges reliably, making it a versatile option if you're running multiple upper receivers or building out a multi-caliber platform.
Marlube is a wear-in coating rather than a wear-off coating, meaning it actually improves with use as it burnishes into the stainless steel surface. It provides self-lubricating properties that help the magazine feed smoothly and resist corrosion without needing external lubrication.
Stainless steel magazines are typically tighter fitting than polymer alternatives due to their rigid construction. Most users report the magazine functions well once broken in, though some find the last round or two require firm pressure to load. This tightness is actually a sign of quality fit and contributes to reliable feeding.
Absolutely. The interior dimensions of 2.316" +/- .002" are specifically optimized for the 6.5 Grendel cartridge and make these magazines an excellent choice for reloaders who want precision dimensions.
