The Sons Of Liberty Gun Works M4-L89 14.5" 5.56 P&W Plan B Black rifle is built for shooters who demand a refined AR platform with dependable performance. Centered around SOLGW’s Liberty Fighting Barrel and the L89 Drivelock handguard, this semi-automatic AR delivers a rigid, free-floated front end with 7-sided M-LOK slots and integral QD sling cups. A pinned and welded Plan B flash hider brings the 14.5" barrel to a 16" overall length while maintaining a compact, well-balanced feel. This configuration uses an enhanced A5-length buffer system for smoother recoil management, paired with a Liberty 2-stage trigger, Liberty charging handle, and ambidextrous safety for confident control. The forged receiver set, B5 stock, and included 30-round magazine make it a capable choice for range work, training, and general-purpose defensive use.
