The Fortis License Gen II AR-15 Lower Receiver (brand part no. L-7075-GEN2-S) is a billet lower machined from 7075-T6 aluminum, built by Fortis Manufacturing as the standard 7075 configuration in their License lineup. It’s a stripped lower receiver, giving builders a precision-machined starting point for a semi-auto AR-15 without the extra cost of Fortis’s separate carbon-fiber variant. Fortis cuts the License to Mil-Spec dimensions, so it accepts standard AR-15 lower parts kits, triggers, and buffer tubes without modification. Among rifle lowers, this License Gen II suits builders who want genuine billet construction and Fortis’s fit and finish at a lower price point than their carbon-fiber option.
