The ArmaLite AR-10 Model AR103GN18 is a .308 Win/7.62 NATO semi-auto rifle engineered for shooters who demand speed and precision on the competition line. Built around a proven modular platform, this rifle combines match-grade componentry with practical features that make it a genuine contender in 3-gun and tactical rifle competitions. Whether you're stacking targets at distance or running dynamic stages, the AR103GN18 delivers the accuracy and reliability that separate winners from the rest of the field.
The 18-inch stainless steel barrel is crowned with ArmaLite's tunable muzzle brake, giving you the flexibility to dial in the recoil management that works for your shooting style and competition rules. A crisp Timney 4-pound single-stage trigger breaks clean and predictably—no creep, no surprises when you need a fast, accurate shot. The lightweight MBA-1 adjustable buttstock lets you dial in both cheekpiece height and length-of-pull so the rifle shoulders the same way every time, a detail that matters when you're running stages under the clock.
Ergonomics favor the competitor: an ambidextrous safety keeps you shooting without fumbling, the Raptor charging handle cycles smoothly whether you're right or left-handed, and the Ergo wide grip fits naturally in competitive holds. At 8.9 pounds, the AR103GN18 stays light enough to manage through transitions without fatiguing you over a long match day. Aluminum receivers keep weight down without compromise, and black anodized surfaces deliver the finish you expect. Out of the box, you'll find a 25-round Magpul PMAG included—the magazine choice of serious competitors.
This is a rifle that ships ready to compete. No hunting-focused compromise, no budget-cut shortcuts. Just the features and components that matter when milliseconds and inches count.
