Chattahoochee Munitions sells this 22 ARC AR15 magazine as the factory magazine for its CM15 22 ARC rifles and upper: a 10-round DURAMAG magazine in 410 stainless steel with a T-360 coating, tested by Chattahoochee Munitions in the CM15. One ships with every CM15 22 ARC rifle.
22 ARC uses the .441-inch case head shared with 6mm ARC and 6.5 Grendel, which is wider than the 5.56 NATO case, so standard 5.56 magazines do not feed it reliably. A 22 ARC AR15 needs a magazine made for this case family, plus a matching bolt and barrel. See every configuration in Flight Deck 22.
Why a Dedicated 22 ARC AR15 Magazine
The wider case needs a magazine body, follower and feed lips shaped for it, so each cartridge is presented to the chamber consistently. 22 ARC loaded ammunition is designed to the AR15’s 2.260-inch magazine length; see the SAAMI announcement accepting 22 ARC for the cartridge’s standardization. The 22 ARC is listed on the DURAMAG magazine alongside 6mm ARC and 6.5 Grendel.
Construction
DURAMAG makes the body from 410 stainless steel with its T-360 coating, LipLock feed lips, Advanced Geometry Follower, EverFlex spring and Post & Hole welded construction. It is AR15 pattern, so it fits standard AR15 magazine wells and releases, and it holds 10 rounds, a common capacity limit in many states.

Is it included with the CM15 22 ARC?
