The SOLGW L89 BS V2 upper receiver delivers a complete 5.56 NATO solution with a 13.7-inch barrel optimized for pinned and welded muzzle device configurations. Built on the L89 (License to Carry) platform, this upper is designed for AR-15 lower receivers and balances velocity retention with compact handling. The 13.7-inch length allows shooters to achieve a legal 16-inch overall barrel length when paired with an appropriate muzzle device, making it a practical choice for defensive and duty applications.

Constructed with a mil-spec forged upper receiver and a medium-profile barrel, this upper features a durable black finish. The HUX rail system provides M-LOK attachment points for accessories while maintaining a low-profile design. Upper includes bolt carrier group and charging handle. Installation requires standard AR-15 armorer's tools; professional pinning and welding of muzzle device recommended to meet NFA compliance.
