Stag Arms Stag15 Tactical Rifle .300 BLK – 16″
Fully Assembled and Range Ready from Stag Arms!
The Stag Arms Stag15 Tactical Rifle .300 BLK is purpose-built for shooters who want versatility, reliability, and enhanced performance in a fully assembled AR-15 platform. Chambered in .300 AAC Blackout, this rifle is ideal for suppressed shooting and performs exceptionally well with both subsonic and supersonic loads. Built around a 16″ 4150 CrMoV barrel with a 1:7 twist rate, the rifle offers optimal stabilization for a wide range of bullet weights.
This rifle features a pistol-length gas system for reliable cycling across various ammunition types and operating conditions. The gas system is paired with a low-profile gas block to maintain a sleek, unobstructed design. The Mil-Spec M16 bolt carrier group is coated in black nitride, providing increased wear resistance and smoother operation. Forged from durable 7075-T6 aluminum, the receiver set is precision-machined and hardcoat anodized for long-lasting durability.
The free-floating Stag 13.5″ M-LOK Handguard delivers a lightweight, slimline profile while maintaining superior strength. It includes an uninterrupted Picatinny rail across the top, giving you full flexibility to mount optics, iron sights, lights, or lasers. With M-LOK slots at multiple positions, it’s easy to customize your setup to match your mission or preferences.
The rifle is outfitted with trusted Magpul furniture, including a MOE SL Stock, MOE Pistol Grip, and Enhanced Trigger Guard for improved ergonomics and handling. The heavy carbine buffer and spring work together to reduce felt recoil and ensure consistent cycling. Whether you’re using it for range training, home defense, or tactical applications, this rifle is engineered to exceed expectations.
Every complete Stag15 Tactical Rifle is backed by Stag Arms’ Transferable Lifetime Warranty and Infinite Shot Barrel Guarantee—giving you complete confidence in your purchase.

Federal law requires that you be 21 years of age or older to purchase a pistol, stripped receiver, or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver, not a handgun or long gun. However, they are still “firearms” by definition and are subject to the same GCA limitations as any other firearm. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
