This is a top-of-the-line AR-15 that comes in at a great price. That's it. We keep things simple, folks but here's the breakdown: If you want to maximize the effective range of 5.56 NATO and .223 Remington (let's face it, empty shelves mean mismatching ammo) safely, then this is the black rifle build kit to buy.
Inside the receivers you'll find some laser-cut and polished M4 feedramps tucked in front of a hyper-accurate, mil-spec barrel with a 1:8 twist and .223 Wylde chamber. It manages both AR cartridges loads reliably, avoiding over-pressure and the early throat erosion .223-chambered barrels suffer when firing 5.56 NATO.
The barrel's forged from 4150 CMV, the same alloy the U.S Army uses. It's also treated with a Melonite (QPQ nitride) finish, superior to chrome lining in every way. All other parts get the mil-spec treatment: Forged receivers, a single-stage trigger that breaks crisp at 4.5 pounds, and a lightweight, free-float M-Lok handguard for your favorite grips, lights, and optics.
