The ArmaLite AR-10 .308 Win 13.5" 3-Gun Rifle is a semi-automatic platform engineered for shooters who demand precision and speed in practical rifle competition. Built on a purpose-driven design, this rifle strips away excess weight and complexity to deliver a nimble, predictable platform that handles the transitions and accuracy demands of three-gun matches. At 8.8 lbs, it's light enough to manage during a string of fire, yet built on proven AR-10 architecture that shooters trust downrange.
The 13.5" stainless steel barrel is fitted with ArmaLite's tunable brake (pinned and welded), giving you the ability to adjust performance for recoil management and muzzle rise control—critical when you're chasing tight stage times. The aluminum upper and lower receivers are hard-anodized black, paired with an MBA-1 adjustable buttstock that lets you dial in length-of-pull and cheekpiece height for a consistent, comfortable position across different shooting positions. An Ergo wide grip and ambidextrous safety ensure intuitive handling whether you shoot right- or left-handed, and the Raptor charging handle gives you positive purchase when you need speed.
The standout feature for competition is the Timney 4-pound single-stage trigger—crisp, predictable, and built for the precision required in precision rifle and three-gun stages. Magazines are simple: the rifle ships with one 25-round Magpul PMAG, and any AR-10 .308 mag platform will work. The entire package—from its 36.3" to 37.3" length-of-envelope to its minimalist, flat-topped design—reflects the compromises top three-gun competitors actually make.
Whether you're stepping into competitive rifle shooting or upgrading your practical rifle setup, the AR-10 .308 3-Gun from ArmaLite is ready to run as it comes out of the box.
