SOLGW East India Starter Kit, 16 in. LFB, 5.56 NATO

The Sons of Liberty Gun Works (SOLGW) East India Starter Kit (brand part no. EIC-16LFB-556) is a 16-inch 5.56 NATO AR-15 upper build kit designed as a foundation for shooters finishing their own rifle. It ships with a properly timed USGI barrel nut already installed, along with the dust cover and forward assist in place, so a builder can skip the trickiest part of assembling an upper without needing barrel-and-gas-block installation experience. The 16-inch barrel runs a mid-length gas system with a 1:7 twist for reliable cycling with common 5.56 loads, and the matte black finish matches typical mil-spec AR builds. It’s aimed at shooters who want to add their own bolt carrier group, charging handle, and muzzle device to finish a rifle their way.
