The Sons of Liberty Gun Works M4 Lower (brand part no. M4LOWERLFTA5BRAVO) is a complete, mil-spec AR-15 lower receiver configured for a left-handed A5 Bravo build, rated multi-caliber. SOLGW builds on the philosophy that there’s no substitute for quality mil-spec-or-better parts and that a rifle should be built right the first time, ready for hard use out of the box. This left-handed configuration ships with the Rebellious Stripes lower finish, a 9-Position Loyal 9 A5 receiver extension, A5H2 buffer with Sprinco green spring, a quick-detach endplate with a staked Forward Controls Design castle nut, an LFT trigger, mil-spec safety, B5 grip, enhanced aluminum trigger guard, and a SOPMOD Bravo stock all installed. It’s a specialized, fully built option for left-handed shooters who want a true left-side ejection setup without sourcing and assembling a dozen individual parts.
