The DURAMAG 6.5 Grendel / 6mm ARC / 22 ARC AR15 Magazine is a 26-round stainless steel magazine built for specialty AR-15 cartridges that require more than a standard 5.56 magazine geometry. Formerly associated with the C Products / C Products Defense name, this magazine line is now sold under the DURAMAG brand.

This magazine is designed for 6.5 Grendel, 6mm ARC, and 22 ARC AR-15 pattern rifles. These cartridges demand a purpose-built magazine for proper stacking, feeding, and internal cartridge clearance, and DURAMAG specifically lists this magazine family for 6.5 Grendel, 6mm ARC, and 22 ARC use.

The stainless steel magazine body provides strength and durability, while DURAMAG’s internal geometry is designed to support reliable feeding from the first round to the last. The magazine also uses DURAMAG’s T-360 coating, LipLock technology, Advanced Geometry Follower, EverFlex anti-fatigue spring, and Post & Hole welded construction.

If you are building or feeding an AR-15 in 6.5 Grendel, 6mm ARC, or 22 ARC, this 26-round DURAMAG offers the proper cartridge-specific magazine geometry instead of relying on a standard 5.56 magazine that was not designed around these case dimensions.
