CM10 7mm-08 Rem 18″ Rifle AR10 FDE Metallic

7mm-08 Rifle 18″ AR10 | Ultimate Big-Game Hunting Accuracy

This is a 7mm-08 rifle from Chattahoochee Munitions. We have been building in less mainstream calibers since our inception, both in AR and bolt-action platforms. 8.6BLK, 243 Win, 22-250 Rem, 338 Spectre, 400 Legend, 338 Federal, etc. Experience building with various lowers, uppers, and handguards, both in low and high profile, allowed us to weigh all pros and cons and create our perfect version of the rifle.

This will be one of the sturdiest-feeling weapons as everything is designed in tight tolerances. All of our rifles are equipped with HIPERFIRE (High Performance Firearms) Triggers; all are 2.5lb single stage Reflex (curved) or Competition (straight with shoe) or X2S Mod3 2-Stage; Reflex is pictured, Odin Adjustable Buffers, and Superlative Arms adjustable gas blocks.

Masterclass Machining & Component Selection

Every single 7mm-08 Rifle that leaves our Roswell, Georgia facility is built to ultra-tight machining tolerances to eliminate upper-to-lower play and maximize precision stability:

Why Choose a 7mm-08 Rifle for Big Game Hunting?

The 7mm-08 Remington cartridge has long been celebrated by precision marksmen and big-game hunters. Created by necking down a standard .308 Winchester case to fire high ballistic coefficient (BC) .284 caliber bullets, a 7mm-08 Rifle achieves higher downrange velocities and flatter trajectories than a traditional .308 Win, while generating substantially less recoil than heavy magnum calibers like the 7mm Rem Mag or .30-06.

When built on our semi-automatic CM10 platform, your 7mm-08 Rifle delivers quick follow-up shots without sacrificing the kinetic energy retention required for ethical medium and large game hunting.

Frequently Asked Questions (FAQ)

1. What makes a semi-automatic 7mm-08 Rifle better than a bolt-action?

While traditional bolt-action rifles are popular for hunting, a semi-automatic 7mm-08 Rifle provides lightning-fast follow-up shots without forcing you to break your cheek weld or re-acquire your sight picture. Combined with our adjustable gas block and low-mass BCG, recoil is dramatically softened compared to a bolt gun.

2. Which magazines fit this 7mm-08 Rifle?

Because the 7mm-08 round shares its parent case dimensions with the .308 Winchester, this rifle feeds reliably using standard AR10 / SR25 pattern 7.62x51mm magazines, such as the included 10-round Magpul PMAG.

3. Can I run a suppressor on this 7mm-08 Rifle?

Yes. The 18″ stainless barrel is threaded in standard 5/8×24 pitch and features a Superlative Arms adjustable gas block. You can select your preferred muzzle device host (SilencerCo ASR, Dead Air Keymo, Q Cherry Bomb, YHM, Rugged) during purchase.

4. What upper/lower standard does this AR10 platform use?

Our CM10 receiver set is CNC machined from 7075-T6 billet aluminum following SR25 patterns and DPMS High Profile specs (including 16TPI barrel nut threads) for maximum component compatibility.

5. What is the current delivery lead time for custom rifle orders?

Custom build production for each 7mm-08 Rifle currently carries an estimated 2-week lead time from order completion to FFL transfer shipment.
