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. 5/8A-24 Threading for Suppressors 5/8A-24 thread pitch rather than standard 1/2A-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.

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.
