Dual Taper Lock (DTL) System

Proprietary tapered barrel extension and tapered barrel create a push-pull relationship ensuring bore centricity between upper receiver and barrel. Delivers exceptional rigidity under extreme impacts. Thermal expansion rings guide the barrel to expand along the bore axis rather than deflecting—maintains point of impact during prolonged shooting. Main barrel nut is also compatible with mil-spec barrels by reversing.

Helix Gas Regulating Barrel System

Integrated gas regulating barrel system works in unison with the barrel for optimum durability—not merely an adjustable gas block. Rock-solid system critical for hard-use suppressed firearms. Ensures consistent function across varying ammunition types and suppressed or unsuppressed configurations.

11.5" Precision Lapped Barrel

416-R stainless steel barrel gun-drilled and reamed with 5R rifling. Increased cycle times and frequent tool changes maintain tighter tolerances across the production run. Lapped to reduce tooling marks and achieve superior bore finish. Fully stress relieved and precision air gauged before profiling, threading, and chambering. Black nitride finish.

Slick Side Upper Receiver

Slick side upper receiver omits the forward assist for a clean, uncluttered profile. The absence of the forward assist reduces snag points and weight while maintaining a streamlined appearance on the upper receiver.

223 Wylde Chamber

223 Wylde hybrid chamber delivers match-grade accuracy with .223 Remington while safely handling 5.56 NATO pressures. Provides versatility without compromising precision.

Grey Cerakote Finish

Grey Cerakote finish provides corrosion resistance and surface protection. Cerakote delivers superior wear resistance and durability compared to standard anodizing—withstands rigorous field use and environmental exposure.

Zero Short Reset Trigger

Zero pre-travel and zero post-travel with short, positive reset. Smooth, crisp trigger break for fast, accurate shooting. Competition-grade performance in a duty-ready package.

Stryker Ambidextrous Charging Handle

Ambidextrous charging handle with extended latches provides positive purchase for reliable operation with gloves. Allows multiple methods of manipulation regardless of shooting side or position.

Plan B Muzzle Device

Plan B compatible muzzle device enables fast, secure suppressor attachment for Plan B equipped suppressors.

M-LOK Handguard

Proprietary handguard mount with anti-rotation pins delivers extreme rigidity through the dual taper mounting system. Five full-length sides of M-LOK slots plus two additional front slots—partial seven-sided M-LOK for extensive accessory mounting.

Ambidextrous Controls

Ambidextrous magazine release, bolt release, and enhanced bolt catch/release. 45/90° modular safety selector converts from standard 90° to 45° throw by rotating drum 180° inside lower receiver.

Blackout Dynamics BCG

8620 steel carrier with shot-peened 9310 steel bolt. Batch high-pressure tested and individually magnetic particle inspected after heat-treat for reliability and longevity.

QD Sling Mount

Billet steel low-profile rear QD plate with anti-rotation limits for ambidextrous sling use. The Blackout Dynamics Quantum DTL-X Helix Grey Slick Side delivers precision AR pistol performance—Dual Taper Lock with Helix gas system and Plan B suppressor compatibility for 223 Wylde accuracy.
