Description
The ArmaLite AR-10 3-Gun Rifle 13.5″ SA 308 Win 13.5″ Barrel, MBA-1 Stock Black, 25rd is a purpose-built competition rifle designed for the 3-Gun circuit. It’s a .308 Winchester platform with a short, 13.5-inch barrel for fast handling, paired with an adjustable Magpul MBA-1 stock for precise length-of-pull and cheek weld. This configuration prioritizes speed and control in dynamic shooting sports.
Key Features
- 13.5″ Barrel: The short barrel profile makes this .308 incredibly maneuverable for quick transitions between targets—a must for 3-Gun stages.
- Magpul MBA-1 Stock: Fully adjustable for length and cheek height. I’ve found this lets you lock in a perfect, repeatable weld for those longer shots.
- 25-Round Magazine: High capacity means fewer reloads in a stage. It’s a simple advantage.
- 3-Gun Ready Configuration: From the muzzle device to the handguard, it’s set up for competition out of the gate. No gunsmithing required to get started.

Weighing in at roughly 9.5 pounds unloaded, it has a solid, planted feel without being a burden when you’re moving. The price point of $2148.64 positions it as a serious tool for serious competitors, not just a plinker. It ships to Missouri and compliant US states, ready for your FFL transfer. Here’s the thing—while it’s a competition beast, the .308 chambering and robust AR-10 platform mean it’s far from a one-trick pony.
Who This Rifle Is For
This is first and foremost for the 3-Gun competitor who wants the power and downrange authority of .308 in a faster-handling package. It’s also a great fit for the shooter who wants a highly adaptable, short-barreled AR-10 for tactical training or as a formidable defensive rifle. If you’re used to the AR-15 platform but need more punch, this is a logical, albeit heavier, step up.
Pros & Cons
Pros: The maneuverability is its biggest sell. The MBA-1 stock is a proven winner for precision. ArmaLite’s heritage with the AR-10 platform means solid reliability and mil-spec compatible parts. It’s a complete, ready-to-run system.
Cons: That short barrel comes with significant blast and noise—muzzle devices and hearing protection are non-negotiable. The .308 round in a 13.5″ barrel also loses some velocity compared to a rifle-length gas system. It’s not a lightweight, and ammunition cost is higher than 5.56.
Frequently Asked Questions
Q: Is this rifle compatible with other AR-10 parts, like triggers or handguards?
A: Mostly, yes. It uses the ArmaLite-pattern AR-10 platform. Triggers, pistol grips, and many small parts are standard. The upper and lower receivers are proprietary to ArmaLite, so handguard and stock compatibility is specific to that pattern—do your homework before swapping.
Q: How does the 13.5″ barrel handle with .308 recoil?
A: It’s lively, but manageable. The rifle’s weight and the effective muzzle brake help a lot. Recoil is sharper and more direct than a longer barrel, but with proper technique, fast follow-up shots are absolutely achievable. I’ve put a few hundred rounds through similar setups and it’s more about control than punishment.
Q: Can this be used for hunting in Missouri?
A: Legally, yes, the .308 Winchester is an excellent deer cartridge. Practically, the short barrel makes it handy in a blind or thick brush. However, check your local regulations on minimum barrel length for hunting, and consider the significant report. For most hunting scenarios, a longer barrel is preferable for ballistics and noise.
If you’re looking for a competition-proven .308 that prioritizes speed without sacrificing adjustability, this ArmaLite build is a compelling option. See the full details and availability at firearms-missouri.com for Missouri residents and nationwide.
