CM15 22 ARC 16″ AR15 Rifle – Black Tungsten

The CM15 22 ARC Target Rifle combines the ballistic capabilities of 22 ARC with Chattahoochee Munitions’ semi-automatic AR-15 platform in a compact 16-inch configuration. It pairs a fluted 416R stainless steel barrel with CM billet receivers, a rifle-length gas system, adjustable gas block, adjustable buffer system, TriggerTech AR15 Duty trigger, and a CM-vetted 22 ARC AR15 magazine.

The 16-inch configuration gives target shooters a shorter alternative to CM’s 18-inch and 20-inch CM15 rifles while retaining the familiar controls, magazine architecture, accessory compatibility, and semi-automatic operation of the AR-15 platform.

This 22 ARC Target Rifle is finished in Black Tungsten Cerakote with Black B5 furniture. It is a complete CM-manufactured firearm built around the CM15 receiver system and configured for shooters who want a compact semi-automatic 22 ARC rifle for recreational and precision-oriented target shooting.

Why Choose a 22 ARC Target Rifle?

22 ARC brings modern .224-caliber projectile capability to the AR-15 platform. For target shooters, the cartridge combines relatively low recoil with aerodynamic projectile options and the rapid follow-up capability of a semi-automatic firearm.

The 16-inch 22 ARC Target Rifle occupies the compact end of the CM15 rifle family. It provides reduced overall length compared with CM’s 18-inch and 20-inch configurations while maintaining a rifle-length gas system and a 15-inch handguard.

The CM15 also incorporates adjustable gas and buffer systems. A Superlative Arms adjustable gas block and ODIN Works adjustable heavy buffer provide multiple points of adjustment within the operating system.

For a broader comparison of CM15 and CM7S platforms, barrel lengths, applications, and suppression considerations, read the 22 ARC Rifle Guide. The complete caliber family is available through Flight Deck 22.

16-Inch 1:7 Twist 22 ARC Barrel

The barrel is central to the configuration of this 22 ARC Target Rifle. The CM15 uses a 16-inch fluted 416R stainless steel barrel finished in Black Cerakote.

CM15 AR-platform 22 ARC barrels use a 1:7 twist rate. The barrel also incorporates a shouldered crown, .750-inch gas journal, 1/2×28 muzzle threads, and a rifle-length gas system.

The fluted profile helps control barrel weight while retaining the 16-inch barrel configuration. Combined with the CM15 receiver and handguard system, it provides the foundation for a compact semi-automatic target rifle.

16-Inch Barrel Specifications

• Chambering: 22 ARC
• Length: 16″
• Material: 416R stainless steel
• Profile: Fluted
• Finish: Black Cerakote
• Twist: 1:7
• Crown: Shouldered
• Muzzle threads: 1/2×28
• Gas journal: .750″
• Gas system: Rifle length

Rifle-Length Adjustable Gas System

The 22 ARC Target Rifle uses a rifle-length gas system with a Superlative Arms .750 Adjustable Gas Block. On this Black Tungsten configuration, the gas block has a Melonite finish.

The adjustable gas block works with the ODIN Works adjustable heavy buffer to provide multiple points of adjustment within the semi-automatic operating system. Changes in ammunition, muzzle devices, and suppressor configurations can alter the amount of gas and energy acting on the rifle, making this adjustability a useful part of the CM15 system.

Target Shooting with the CM15

The CM15 22 ARC Target Rifle provides the advantages of a semi-automatic platform for recreational and precision-oriented target shooting. Low recoil helps the shooter maintain position and sight picture, while semi-automatic operation permits subsequent shots without manually cycling the action.

The 15-inch handguard provides room for supported shooting positions and accessories, while the full-length Picatinny top rail accommodates a wide range of customer-selected optics. The adjustable stock allows the length of pull to be adapted to the shooter and shooting position.

Actual accuracy, velocity, and effective range depend on ammunition, projectile selection, environmental conditions, optics, shooter capability, and other variables. CM does not rely on arbitrary range claims to define the capability of the rifle.

Suppressing the 16-Inch CM15

The 22 ARC Target Rifle is suppressor ready with 1/2×28 muzzle threads. A suppressor can substantially reduce muzzle blast, which may be useful during extended target sessions, but suppressor backpressure also becomes part of the operating-system equation on a semi-automatic rifle.

For the CM15, Chattahoochee Munitions generally favors a flow-through suppressor. Reducing additional backpressure can make it easier to maintain a balanced operating system while limiting unnecessary gas returned through the action.

The Superlative Arms adjustable gas block and ODIN Works adjustable heavy buffer provide additional tuning capability when the rifle is operated suppressed.

Flight Deck 22 is built around supersonic 22 ARC performance. A suppressor reduces muzzle blast but does not eliminate the ballistic crack produced by a projectile traveling above the speed of sound.

CM15 15-Inch M-LOK Handguard

A 15-inch CM15 lightweight handguard surrounds the barrel and gas system. The handguard is machined from 6061 aluminum and finished in Black Tungsten Cerakote.

The attachment system uses a steel barrel nut and dual-taper interface. A full-length Picatinny top rail provides optics and accessory mounting space, while M-LOK interfaces are positioned along the sides and bottom.

Handguard Features

• Length: 15″
• Material: 6061 aluminum
• Attachment: Dual-taper system
• Barrel nut: Steel
• Top rail: Full-length Picatinny
• Accessory interface: M-LOK
• QD sockets: 3 and 9 o’clock positions
• Finish: Black Tungsten Cerakote
• Rail covers: B5 Systems, Black

Ambidextrous Charging Handle and Controls

The CM15 upper receiver includes a CM15 ambidextrous charging handle manufactured from 7075 aluminum, along with a dust cover and forward assist.

The charging handle complements the ambidextrous safety, magazine release, and bolt release incorporated into the CM15 lower receiver, providing accessible controls from either side of the rifle.

22 ARC AR15 Magazine

Each complete 22 ARC Target Rifle includes one 10-round CM-vetted DURAMAG in Black. The CM15 uses an AR-15 magazine architecture rather than the AICS-pattern magazine used by the CM7S bolt-action platform.

Additional magazines are available through the CM 22 ARC AR15 Magazine product page.

CM’s validation applies to the magazine as used with our CM15 22 ARC firearms. Function with every possible combination of third-party receivers, uppers, barrels, or other components is not guaranteed by Chattahoochee Munitions.
