Description
Picture this: you need a rifle that bridges the gap between a standard AR-15 and a full-power battle rifle. You need reach, authority, and the ability to handle anything from Missouri whitetail to serious defensive scenarios. The Windham SRC-308-MA .308 16.5″ Medium Profile Barrel Welded Compliant Compensator 10rd Mag is that rifle. It’s a purpose-built, feature-complete .308 AR-platform carbine designed for reliability and immediate deployment. This rifle delivers the .308 Winchester’s proven terminal performance in a maneuverable, 16.5-inch barrel package, arriving ready for duty with a welded compensator and a 10-round magazine to meet specific compliance needs. At $1169.44, it represents a serious value in the modern sporting rifle market.
The Windham SRC-308-MA is built around a robust, direct-impingement operating system. Its medium-profile barrel strikes the perfect balance between weight and heat dissipation—heavy enough for sustained fire, light enough for all-day carry. The heart of the system is the permanently attached, state-compliant compensator. This isn’t an add-on; it’s welded, making the overall barrel length legal while helping to manage the .308’s substantial recoil impulse. The result is a smoother, faster follow-up shot. That said, the real benefit is the out-of-the-box readiness. This rifle fits out of the box with any mil-spec AR-10 pattern lower receiver, requiring no gunsmithing to become a complete, functional firearm. It’s a true plug-and-play upper for those building, or a complete system as sold.
Key Features & Performance
Let’s break down what makes this SRC-308-MA work. The 16.5-inch chrome-moly barrel is the centerpiece. It provides optimal velocity for the .308 cartridge without the unwieldy length of a 20-inch rifle. Chambered in .308 Winchester/7.62x51mm NATO, it gives you the flexibility to run a wide range of ammunition. The welded muzzle device is a key feature, ensuring compliance without sacrificing performance. The rifle uses a standard carbine-length gas system for reliable cycling, paired with a full-length Picatinny top rail for optics and a free-float handguard for accessory mounting and a consistent point of impact.
The rifle ships with a 10-round magazine, aligning with capacity regulations in several jurisdictions. This controlled capacity forces deliberate shot placement—a practical discipline for any shooter. The total weight of the complete rifle hovers around 8.5 pounds, making it a substantial but manageable platform. The use of common AR-10 parts means maintenance and customization are straightforward. Need a different stock or grip? The buffer tube is mil-spec, and the fire control group is standard. This rifle is compatible with components from brands like Magpul and B5 Systems, allowing you to tailor the fit to your needs.

Pros, Cons, and Ideal User
Pros: The primary advantage is immediate compliance and capability. The welded muzzle device solves a legal hurdle. The .308 chambering provides undeniable power for hunting medium to large game or for defensive use where barrier penetration and downrange energy are considerations. The 16.5-inch barrel offers a great balance for vehicle use or wooded terrain. Windham Weaponry’s reputation for quality manufacturing behind this build is a significant trust factor.
Cons: The fixed muzzle device limits your ability to swap for a suppressor mount or other brake without a gunsmith’s intervention. The 10-round magazine, while compliant, may be less than some users desire for other applications—though additional magazines are readily available. As with any .308 AR-platform rifle, it will be heavier and have more recoil than a 5.56mm counterpart.
Who is this for? This is for the Missouri hunter who wants a versatile, semi-auto platform for deer and boar. It’s for the prepared citizen who understands the ballistic advantages of a .308 for homeland defense. It’s also an excellent choice for the shooter in a regulated state seeking a high-quality, feature-compliant rifle without compromise on core performance.
