The 16-inch 4140 chrome-moly steel barrel uses a lightweight profile to keep the rifle quick on target while maintaining durability. Its 1/2x28 threaded muzzle accepts standard flash hiders, brakes, or suppressor adapters.
A mid-length gas system pairs with the lighter barrel to smooth out recoil and reduce parts wear, offering a more comfortable shooting rhythm than carbine-length setups.
The 15-inch free-float aluminum M-LOK handguard extends the full length of the gas system, giving ample real estate for lights, grips, and bipods while keeping weight forward of the receiver to a minimum. A continuous Picatinny top rail aligns perfectly with the upper receiver for seamless optic placement.
Forged 7075-T6 upper and lower receivers wear Del-Ton’s “DTI” triangle roll mark and a hard-coat anodized black finish. The rifle accepts all standard MIL-STD AR-15 parts, making future customization straightforward.
A six-position collapsible polymer stock, A2-style grip, and manual safety selector round out a dependable, optics-ready rifle built in Elizabethtown, North Carolina.
