The Sons of Liberty Gun Works L89 V2 Complete Upper chambered in 5.56 NATO with an 11.5 inch barrel and an A2 profile, finished in black (SOLGW part no. M4L89UPPER-11.5-556), gives builders a ready-to-run upper half for an AR-15 project. This complete upper ships as an upper receiver group only, with no lower receiver, stock, or fire control components included, so it is not itself a serialized firearm. It is part of SOLGW’s L89 line, built around the company’s precision manufacturing standards for both barrel and handguard fit.

Frequently Asked Questions

Does this upper include a lower receiver? No, this is a complete upper receiver group only; a separate lower receiver is required to build a complete firearm.

Is an 11.5 inch barrel legal to buy as an upper? Yes, an upper receiver group with no lower included is an ordinary Title I part and is not itself a regulated firearm. Installing it on a rifle-configured lower without a compliant pin-and-weld muzzle device would create a short-barreled rifle requiring ATF approval, so it should be paired with a pistol-configured lower or a registered SBR.
