CM7S 22 ARC Bolt Action Hunting Rifle 18″ – WOOX Walnut Stock

Chattahoochee Munitions manufactures the CM7S 22 ARC Bolt Action Hunting Rifle, a complete factory 18-inch bolt action with WOOX walnut furniture, a 1:8 twist Mos-Tek 416R stainless barrel in E100 Blackout Cerakote and a TriggerTech Remington 700 Primary trigger. It weighs 8 lb 14 oz and ships with one 10-round 22 ARC AICS magazine.

This 22 ARC Bolt Action Hunting Rifle pairs the CM7S action with a walnut Exactus stock, a walnut Furiosa forend and MDT bottom metal from WOOX, in place of the telescoping CM7 aluminum chassis used on the other CM7S 22 ARC models. It has an 18-inch barrel and a full-length walnut stock, so it is a standard rifle under federal law, with no NFA paperwork.

Optics and suppressors shown in product photographs are not included in the purchase price.

Why a 22 ARC Bolt Action Hunting Rifle

22 ARC fires long, high ballistic coefficient .224-inch bullets from 62 to 88 gr at supersonic velocity, with light recoil. In a conventional rifle-length walnut-stocked bolt action, the 22 ARC Bolt Action Hunting Rifle suits coyotes, varmints and hogs, and deer where state law allows .224-inch centerfire cartridges, with an expanding hunting bullet and sensible range. The 18-inch barrel keeps more of the cartridge’s velocity than the 12.5-inch models; see the calculated figures by barrel length in 22 ARC ballistics.

Read 22 ARC for coyotes and hogs and 22 ARC for deer for bullet choice, range and shot placement.

WOOX Walnut Stock, Forend and Bottom Metal

WOOX supplies the furniture; Chattahoochee Munitions manufactures the firearm. The walnut Exactus stock has an adjustable cheek riser and a buttpad adjustable for height and length of pull, plus a bottom Picatinny rail and a QD sling mount. The walnut Furiosa forend carries M-LOK slots at 3, 6 and 9 o’clock for a bipod or light.

MDT bottom metal provides the AICS-pattern magazine interface. Length of pull adjusts from 13.75 to 14.75 inches, a conventional hunting-stock fit that differs from the CM7 chassis models.

CM7S Action

The CM7S action is designed to Chattahoochee Munitions specifications on a Remington 700 footprint. Three locking lugs give a 60-degree bolt throw, and the one-piece spiral-fluted bolt has a .718-inch body, an M16-style extractor and a .062-inch firing pin. An integrated recoil lug, a pinned 20 MOA Picatinny rail, wire EDM raceways, a side bolt-stop release, an oversized bolt knob and tool-less fire-control removal complete the action, which has a full PVD coating.

18-inch Mos-Tek Barrel and 1:8 Twist

The 18-inch barrel is made by Mos-Tek from 416R stainless steel with 5R rifling and a 1:8 twist, finished in E100 Blackout Cerakote, with a shouldered crown, 1/2×28 muzzle threads and Remage barrel-nut mounting. The 1:8 twist stabilizes 22 ARC bullets from 62 gr varmint loads through the 88 gr ELD Match. Read 22 ARC twist rate.

TriggerTech Remington 700 Primary

The TriggerTech Remington 700 Primary trigger comes in a flat or curved blade and adjusts externally from 1.5 to 4.0 lb, using TriggerTech’s Frictionless Release Technology. Older photographs may show flat triggers with trigger shoes; current flat triggers do not include them.

Magazine

The 22 ARC Bolt Action Hunting Rifle ships with one 10-round MDT polymer 22 ARC AICS magazine, a short-action AICS-pattern magazine that feeds through the MDT bottom metal. The CM7S does not use the AR15-pattern magazine of the CM15.

Suppressing the CM7S 22 ARC Bolt Action Hunting Rifle

Because the CM7S is a manually operated bolt action, Chattahoochee Munitions recommends an enclosed suppressor rated for .224 caliber, mounted on the 1/2×28 threads. Nothing cycles when it fires, so the action adds no noise and nothing depends on gas pressure. 22 ARC is supersonic, so a suppressor reduces muzzle blast but the bullet still cracks. Read the 22 ARC suppressor guide.
