14.5" P3 Chrome-Lined Barrel

14.5" P3 polygonal rifled barrel provides superior precision, barrel life, and ammunition forgiveness. Chrome-lined chamber and bore resist corrosion and extend service life. Pinned and welded HUX QD flash hider brings overall length to 16" for legal compliance while maintaining compact handling.

Mid-Length Gas System

Mid-length gas system on 14.5" barrel balances reliability with reduced recoil impulse. The longer dwell time compared to carbine-length systems improves consistency with suppressed and unsuppressed fire.

.223 Wylde Chamber

.223 Wylde chamber accepts both .223 Remington and 5.56 NATO ammunition. Provides accuracy advantage of .223 match chamber while maintaining 5.56 NATO pressure tolerance for duty reliability.

5/8×24 Threading for Suppressors

5/8×24 thread pitch rather than standard 1/2×28 reduces stress on threads under suppressor use. HUX QD flash hider provides quick-detach compatibility with FLOW 556K/6K suppressors.

Liberty 2-Stage Trigger

L2S trigger provides 4.5 lb total pull weight with two-stage break. First stage takes up slack, second stage provides clean release—balances precision with duty-grade reliability.

A5H2 Intermediate Buffer System

A5H2 intermediate buffer system with SOLGW castle nut enhances reliability and shootability with suppressors. The longer buffer stroke and H2 weight reduce felt recoil and carrier velocity.

L89 MLOK Handguard

13.75" L89 MLOK handguard with titanium barrel nut and 7-sided MLOK slots. Drive-Lock mounting with anti-rotation tabs and stainless steel pin connects upper and handguard for superior lockup.

Legendary Bolt Carrier Group

SOLGW Legendary BCG machined from Carpenter No. 158 steel. HPT/MPI tested, shot peened, full-auto profile. Chrome-lined carrier and gas key with staked Grade 8 screws. Tool steel extractor. Individually test-fired on machine gun for function verification.

Rhodesian Brushstroke Cerakote

Cerakoted with Craighead's trademarked Rhodesian Brushstroke camouflage. Each rifle has unique pattern variation. Blackbeard Boarding Party logo deeply engraved—classic pirate flag imagery updated with Revolutionary War weapons.

Ambidextrous Controls

Liberty ambidextrous charging handle accommodates left- and right-handed shooters. 50-degree single-sided quick selector provides rapid transition from safe to fire.
