Weighing in at approximately 6.5 to 7 pounds unloaded, this rifle balances maneuverability with steady shooting. The 300 Blackout round itself is the star here—it uses standard AR-15 bolts and magazines, but its heavier projectile hits harder at typical home-defense or woods-ranging distances than a 5.56mm. When it comes to home defense, especially with a suppressor in mind, having a round that stays subsonic and effective is a serious advantage. The total package price is $1266.92.
Who This Rifle Is For
This Windham is for the practical shooter who values versatility. It’s for the Missouri hunter in dense timber who needs a compact, hard-hitting rifle for whitetail. It’s for the home defender who prioritizes terminal performance and the option for hearing-safe suppressed use. It’s also for the AR enthusiast who wants a dedicated upper but appreciates the value of a complete, factory-tested rifle from a reputable maker like Windham Weaponry.
Pros & Cons
Pros: The 300 BLK caliber offers superior close-to-mid-range energy transfer over 5.56mm in a short barrel. The rifle’s mil-spec construction means broad accessory compatibility—think Magpul grips, Geissele triggers, or SureFire lights. The 16-inch barrel provides optimal velocity without unnecessary length, and the melonite treatment ensures long service life. It’s a turn-key solution for a potent caliber.
Cons: Ammunition cost for 300 Blackout is higher than for 5.56x45mm NATO for practice. If you don’t handload or plan to suppress, some of the cartridge’s main benefits are untapped. The rifle is also a specific tool; if your primary need is ultra-long-range or ultra-high-volume plinking, other platforms might be more economical.
