Sons of Liberty Gun Works M4-L89 16" 5.56 Mid Gas Upper Receiver Group

Sons Of Liberty Gun Works M4-L89 Upper Receiver Group Complete Upper Features The Sons of Liberty Gun Works M4-L89 Upper Receiver Group is built around a 16 inch 5.56 NATO Liberty Fighting Barrel known among SOLGW customers for reliable accuracy and durability across mil-spec compatible AR-15 lower receivers. A forged upper receiver keeps the assembly strong and consistent with mil-spec dimensions so it mates cleanly to nearly any compatible lower. An A2 flash hider caps the muzzle reducing visible signature during low-light firing while remaining a simple reliable muzzle device choice. The Drivelock barrel nut system secures the handguard solidly to the receiver minimizing any play that could affect accuracy or zero retention. The included 15 inch L89 handguard features seven-sided M-LOK slots giving shooters mounting positions nearly all the way around the rail for lights foregrips bipods and other accessories. Integral QD sling mounting points at the barrel nut on both sides of the handguard add flexible sling attachment options without needing separate QD end plates or adapters. Finished in a matte black finish the upper presents a clean consistent look that matches most mil-spec AR-15 builds. This upper does not include a bolt carrier group or charging handle so builders should plan to source those separately but everything else needed for a complete 16 inch 5.56 NATO upper ships ready to install.
