Sons Of Liberty Gun Works Enhanced Blaster Guns Lower Parts Kit Features The Sons Of Liberty Gun Works Enhanced Blaster Guns Lower Parts Kit is built around the Liberty Fighting Trigger Sons of Liberty Gun Works own trigger design intended to give builders a meaningful upgrade over a standard mil-spec unit right from the start of assembly. Paired with it is a B5 pistol grip a widely trusted aftermarket grip known for its ergonomic angle and storage compatible design that improves control over a basic mil-spec grip. A mil-spec safety selector rounds out the primary controls keeping the kit compatible with standard AR-15 lowers and familiar to anyone who has handled a mil-spec rifle before.
