Key Features
- Match-Grade Stainless Steel Barrel (13.50″) — A 1:8 twist rate stabilizes bullets from 55 to 77 grains, giving you pinpoint accuracy at 3-gun distances. Why it matters: You’ll hit steel faster and more consistently, stage after stage.
- ArmaLite Tunable Muzzle Brake — Reduces muzzle rise and allows you to dial in compensation for your load. Why it matters: Faster follow-up shots mean you stay on target through split-second transitions.
- Adjustable Gas Block — Lets you fine-tune gas flow to match your ammunition, reducing recoil and improving reliability. Why it matters: You can run light competition loads or full-power duty ammo without changing parts.
- Timney Single-Stage Trigger — A crisp, consistent pull (typically 3–4 lbs) with zero creep. Why it matters: No surprises when the shot breaks — your rounds go exactly where you aim.
- Luth-AR MBA-1 Adjustable Stock — Offers length-of-pull and cheek riser adjustments for a custom fit. Why it matters: A proper cheek weld and reach to the trigger improve accuracy and comfort during long matches.
Who It’s For
This rifle is built for competitive shooters — 3-gun, practical rifle, and action shooting sports. It’s also a great choice for families who want a single AR that can serve both as a training rifle and a competition-ready platform. If you’re a beginner looking to start competing, this rifle removes the guesswork: it’s tuned from the factory for speed and accuracy.
Pros / Cons
- Pro: Tunable gas block and muzzle brake let you optimize for different ammo types.
- Pro: Timney trigger is a major upgrade over mil-spec — no aftermarket trigger needed.
- Pro: Optics-ready with a low-profile handguard for easy mounting of red dots or LPVOs.
- Con: No iron sights included — you’ll need to add optics or backup sights.
- Con: The 13.50″ barrel may not be legal in all states for hunting; check local laws.

The ArmaLite offers a tunable gas block and muzzle brake at a lower price point, while the Geissele is a battle-proven design with a fixed gas system. The Timney-branded rifle is similar but with a longer barrel — the ArmaLite’s shorter 13.50″ is better for close-quarters stages.
FAQ
What is the barrel twist rate?
The barrel has a 1:8 twist rate, optimized for stabilizing bullets from 55 to 77 grains — ideal for 3-gun and competition loads.
Does this rifle come with a warranty?
Yes, ArmaLite offers a limited lifetime warranty on the receiver and a one-year warranty on other components. Per ArmaLite specs, contact their support team for details.
Is this rifle legal in all states?
The 13.50″ barrel makes it a pistol or SBR in some states if the overall length is under 26″. Check your local laws. In most states, it’s sold as a rifle with a 16″ barrel equivalent due to the pinned muzzle brake.
Can I use .223 Remington or 5.56 NATO ammo?
Yes, the .223 Wylde chamber safely fires both .223 Remington and 5.56 NATO ammunition, giving you more ammo options.
What optics fit the handguard?
The low-profile free-float handguard uses a Picatinny top rail — any standard red dot, holographic, or LPVO will mount directly.
