Key Features
- 24″ Stainless Threaded Barrel (5/8″x24): Why it matters: This longer barrel gives .243 Win extra velocity for flatter trajectories at 300+ yards, and the threading lets you attach a suppressor or muzzle brake easily.
- Tungsten Cerakote Finish: Why it matters: This corrosion-resistant coating protects against sweat, rain, and rough handling, so your rifle stays looking sharp season after season.
- M-LOK Free-Float Handguard: Why it matters: You can mount lights, lasers, or a bipod without interfering with barrel harmonics, improving accuracy and versatility.
- Adjustable Black Synthetic Stock: Why it matters: Length of pull and cheek riser adjustments let you fit the rifle to growing shooters or different shooting positions, promoting consistent cheek weld.
- Mil-Spec Polymer Grip and Trigger: Why it matters: Standard AR-10 grip and trigger mean easy replacement with aftermarket parts if you want a lighter pull or different ergonomics.
Who It’s For
This rifle is ideal for families introducing youth or new shooters to centerfire rifles, because the .243 Win has mild recoil and excellent downrange energy. Hunters targeting deer, antelope, or varmints will appreciate the accuracy potential and threaded barrel for suppressor use. It also works well for shooters who want a lightweight AR-10 that doesn’t punish the shoulder during long range sessions.
Pros and Cons
- Pro: Accurate 24-inch stainless barrel with factory threading saves you the cost of a gunsmith.
- Pro: Tungsten Cerakote finish is tough and looks great—holds up to field use.
- Con: The mil-spec trigger is functional but not match-grade; you may want to upgrade for precision shooting.
- Pro: M-LOK handguard gives you plenty of mounting options without adding weight.
- Con: .243 Win ammo can be harder to find in some rural areas compared to .308 or 6.5 Creedmoor.

FAQ

This rifle uses standard DPMS-pattern AR-10 magazines. Magpul PMAGs and metal GI-style mags work reliably. Capacity varies by state law—5-round magazines are common for hunting.

Yes, the barrel is threaded 5/8″x24, which is the standard for .30-caliber suppressors and muzzle brakes. A thread protector is included.
Can I mount a bipod or sling?
Yes. The M-LOK handguard accepts bipod mounts and sling attachments. The stock also has QD sling swivel sockets.
What twist rate is the barrel?
The barrel has a 1:10 twist rate, which stabilizes most .243 Win bullets from 55 to 100 grains.
