Chattahoochee Munitions manufactures complete 22 ARC firearms on two platforms: the CM15 AR15 as 16, 18 and 20-inch rifles with 1:7 twist 416R stainless barrels, plus a 16-inch CM15 upper for an existing AR15 lower; and the CM7S bolt action as an 18-inch rifle and a 12.5-inch pistol or SBR in the CM7 aluminum chassis, plus an 18-inch rifle and a 12.5-inch SBR with WOOX walnut furniture, all with 1:8 twist Mos-Tek barrels, and CM7S barreled actions in both lengths. Every complete firearm ships with one 10-round magazine.
Flight Deck 22 is the 22 ARC home of Chattahoochee Munitions. The 22 ARC is a .224-inch AR15 cartridge that fires long, high ballistic coefficient 62 to 88 gr bullets, so it drifts less in wind and keeps more energy at distance than 223, with light recoil, for coyotes, varmints, hogs and steel.
What Is 22 ARC?
22 ARC (22 Advanced Rifle Cartridge) is a bottlenecked .224-inch cartridge introduced by Hornady and accepted for standardization by SAAMI in 2024. It is the 6mm ARC case necked down to .224 inch, from the 6.5 Grendel family, so it uses the Grendel’s .441-inch case head and fits the AR15 magazine well. In an AR15 it needs a 22 ARC barrel, bolt and magazine, but it uses a standard lower receiver. Read the 22 ARC rifle guide.

A Supersonic Cartridge for Wind and Reach
22 ARC is a supersonic cartridge. Its long .224-inch bullets resist wind: with the 88 gr ELD Match load, Chattahoochee Munitions calculations show about 16.5 inches of drift at 500 yards in a 10 mph crosswind, against about 36 inches for a common 55 gr 223 load, and more than twice the retained energy. Its bullets are too light for useful subsonic energy, so it is not loaded subsonic for hunting; for heavy subsonic shooting, see the Raptor Paddock. Full charts by barrel length are in 22 ARC ballistics.
CM15 22 ARC AR15 Rifles
Chattahoochee Munitions manufactures the CM15 22 ARC with straight-fluted 416R stainless barrels in a 1:7 twist and E100 Blackout Cerakote, CNC-machined 7075-T6 billet receivers, a Superlative Arms adjustable gas block, an ODIN Works adjustable buffer, a CM15 low-mass bolt carrier group with a 9310 steel bolt, a 15-inch M-LOK handguard, B5 Systems furniture and a TriggerTech AR15 Duty trigger in straight, curved or two-stage straight, 3.5 lb.
| Barrel | Gas system | Weight* | Overall length | Models |
|---|---|---|---|---|
| 16 inch | Rifle-length | 6 lb 6 oz | 33.50 to 36.75 in | Target rifle, AR15, coyote rifle |
| 18 inch | Rifle-length | 6 lb 14 oz | 35.50 to 38.75 in | DMR, SPR, semi auto rifle |
| 20 inch | Rifle +1 | 7 lb 4 oz | 37.50 to 40.75 in | Predator rifle, hunting rifle, varmint rifle |
*With an unloaded magazine and no accessories. Each length comes in Black Tungsten Cerakote, Cobalt Kinetics Green Cerakote and FDE Metallic Cerakote; the finish changes only the color. Browse them in CM15 22 ARC rifles.
CM15 22 ARC Upper
Already own an AR15 lower? The CM15 22 ARC upper is a 16-inch complete upper with a 1:7 416R SPR-profile barrel, rifle-length adjustable gas, a 6061 billet receiver and 15-inch M-LOK handguard, and an optional CM15 low-mass bolt carrier group and ambidextrous charging handle. See CM15 22 ARC uppers.
CM7S 22 ARC Bolt Action Rifles, Pistols and SBRs
The CM7S is a manually operated bolt action with a Remington 700-footprint, three-lug action, an integrated recoil lug and 20 MOA rail, a TriggerTech Remington 700 Primary trigger, either the CM7 billet aluminum chassis or WOOX walnut furniture, a Mos-Tek 416R barrel with 5R rifling and a 1:8 twist, and a 10-round MDT AICS-pattern magazine. Length of pull runs from 6 inches collapsed to 13.5 inches on the chassis models and 13.75 to 14.75 inches on the walnut models.
| Barrel | Configuration | Weight | Overall length | Models |
|---|---|---|---|---|
| 18 inch | Bolt action rifle, CM7 chassis | 7 lb 7 oz | 30.50 to 38.00 in | Precision rifle, bolt action rifle, bolt action |
| 18 inch | Bolt action rifle, WOOX walnut | 8 lb 14 oz | 37.50 to 38.50 in | Bolt action hunting rifle |
| 12.5 inch | Pistol or SBR, CM7 chassis | 6 lb 6 oz | 24.375 to 31.50 in | SBR, pistol, short barreled rifle |
| 12.5 inch | SBR, WOOX walnut | 7 lb 12 oz | 31.75 to 32.50 in | Hunting SBR |
The walnut models pair the CM7S action with a WOOX walnut Exactus stock with an adjustable cheek riser, a walnut Furiosa forend and MDT bottom metal; WOOX supplies the furniture and Chattahoochee Munitions manufactures the firearm. The 12.5-inch chassis CM7S is ordered with a telescoping buttpad as an SBR, which is regulated under the National Firearms Act, or with a Tailhook brace as a pistol; the 12.5-inch walnut model is an SBR. See CM7S 22 ARC.
CM7S 22 ARC Barreled Actions
For your own stock or chassis, Chattahoochee Munitions manufactures the CM7S 22 ARC as a barreled action: the 18-inch barreled action and the 12.5-inch short barreled action, each with a 1:8 Mos-Tek 416R barrel in E100 Blackout Cerakote and a Remington 700 footprint.
22 ARC Bolts and Magazines
The 22 ARC case head is wider than 223, so an AR15 needs a bolt sized for the .441-inch case head, the same family as the 6.5 Grendel and 6mm ARC. Magazines are platform-specific: the CM15 uses the 10-round, 410 stainless steel 22 ARC AR15 magazine, and the CM7S uses the 10-round MDT 22 ARC AICS magazine, which accepts cartridges up to 2.480 inches long.
22 ARC Barrel Length and Twist
Longer barrels keep more velocity; shorter barrels handle better and suit suppressors. Sixteen inches is the light, handy CM15; 18 inches is the all-around length; 20 inches is for open country; and the 12.5-inch CM7S is for blinds, vehicles and suppressed shooting. The CM15’s 1:7 twist and the CM7S’s 1:8 twist both stabilize common 22 ARC bullets from 62 to 88 gr. Read 22 ARC ballistics and 22 ARC twist rate.
22 ARC for Hunting
The 22 ARC suits coyotes, varmints and hogs, and deer where .22 centerfire is legal and with a bullet designed for deer. Some states do not allow .22 centerfire for deer, so check your state’s rules. Read 22 ARC for coyotes and hogs and 22 ARC for deer. To see how the 22 ARC compares with five other predator cartridges, read the predator hunting cartridges guide. The same guide covers the CM10 chamberings in Predator Plains and the 6mm ARC lineup in Overwatch 6.
Comparing 22 ARC with Other Cartridges
- 22 ARC vs 223: same AR15 lower; the 22 ARC carries about 2.7 times the energy at 500 yards with the 88 gr. For 5.56 NATO itself, see What is 5.56 NATO? and Garrison 5.56.
- 22 ARC vs 22 Creedmoor: AR15 against AR10; the Creedmoor is flatter, the ARC is lighter to carry. See What Is 22 Creedmoor?, 22 Creedmoor vs 223 and the CM10 in Predator Plains.
- 22 ARC vs 6mm ARC: same case head, bolt and magazine; the 6mm ARC carries more energy.
- 22 ARC vs 22-250: the 22-250 is flatter inside 400 yards; the 22 ARC drifts less past 300. See What Is 22-250?, 22-250 vs 223 and 22-250 for coyotes.
22 ARC Suppressor Guidance
All Chattahoochee Munitions 22 ARC firearms have a shouldered crown and 1/2×28 threads, with an optional muzzle brake selection or a thread protector. Chattahoochee Munitions recommends a flow-through suppressor on the gas-operated CM15 with supersonic ammunition, to limit back pressure, and an enclosed suppressor on the manually operated CM7S, which does not use gas to cycle. A suppressed 22 ARC still makes a supersonic crack, so wear hearing protection. Read 22 ARC suppressor.

Who makes a 22 ARC bolt action rifle?

AR15. It uses a standard AR15 lower with a 22 ARC barrel, bolt and magazine.
