Sons Of Liberty Gun Works East India Starter Kit Upper Features The Sons of Liberty Gun Works East India Starter Kit is built around the 13.7 inch SOLGW Liberty Fighting Barrel a component known for delivering accuracy and reliability under demanding use. QPQ coated M4 feed ramps improve feeding reliability across a variety of magazine types and ammunition reducing the chance of malfunctions. The barrel is both high pressure tested and magnetic particle inspected two quality control steps that help catch defects before the barrel ever reaches a rifle. A 1/2x28 thread pattern at the muzzle allows builders to install their muzzle device of choice once the kit is assembled. A SOLGW V2 gas block comes pre-installed saving builders the trouble and precision required to properly fit and time a gas block themselves. Properly assembled with a USGI barrel nut the East India Starter Kit is designed as a building block that removes much of the difficulty from finishing a custom upper. It does not include a muzzle device bolt carrier group or charging handle leaving those final components to the builder s preference. This starter kit is an efficient way to begin a 5.56 NATO AR-15 build with a proven SOLGW barrel and gas block already in place available for sale at GrabAGun.
