Premium Barrel Technology:
The Ballistic Advantage Hanson 16″ 4150 CMV Melonite Barrel on the ACI-15 556 DUTY 16 is renowned for its lightweight, shoulder-less profile that maintains rigidity and accuracy while reducing front-end weight. The Nickel Boron barrel extension ensures ultra-smooth cycling and extended wear resistance, while the pinned nitride .750 low profile gas block guarantees rock-solid gas system reliability. The QPQ corrosion resistant finish and 1/7 twist rate make this barrel ideal for a wide range of 5.56 NATO loads, offering both longevity and sub-MOA performance potential.
AR15/M16 Bolt Carrier Group – The Industry’s Best

The BCG is the heart of any AR15 or M16, and ours is engineered to be the most reliable, durable, and precise on the market. Precision-machined from 9310 alloy steel, every bolt is HP proof tested and 100% MPI inspected for flawless strength. The carrier is made from 8620 alloy, full-auto rated, hard chrome lined, and manganese phosphate finished for maximum durability.

Key features include a 4140 tool steel extractor with a 5-coil spring and Viton O-ring, S7 tool steel ejector, corrosion-resistant gas rings, and a robust 4130 chromoly gas key—torqued, sealed, staked, and breakaway tested to spec. The cam pin, firing pin, and all pins are heat treated and built to last. Laser-engraved HPT/MPI markings prove every unit meets the strictest standards.
All components and assembly are 100% made in the USA. If you want the most dependable, hard-use BCG on the market, this is it—no compromises.
Ambidextrous, Enhanced Controls:
The Breek Arms Warhammer Ambi Charging Handle on the ACI-15 556 DUTY 16 delivers effortless, one-handed manipulation from either side of the rifle. Its robust 7075-T6 aluminum construction, extended latches, and gas diversion cut make it a favorite among AR builders looking for high-value upgrades.
Combat-Grade Free-Float Handguard:
The Midwest Industries Combat 15″ MLOK Handguard is a top choice for those seeking a lightweight, rigid, and modular mounting platform. Featuring a patented 4140 heat-treated torque plate, full-length Picatinny rail, multiple anti-rotation QD sling sockets, and seven sides of MLOK slots, this handguard delivers rock-solid accessory mounting and superior heat dissipation—while remaining slim and ergonomic.
