Introducing the Lower Build Kit you didn’t know you needed. The NBS Bare Bones Lower Build Kit. All of our other lower build kits, and many others on the market include a Fire Control Group, Stock and Grip by default, even though many builders opt for an upgraded stock, grip and trigger group. Most of our builds here in the shop include a separately sourced FCG, stock and grip so this kit was born out of necessity and now we’re offering them to all of our customers. Don’t spend your hard earned dollars on parts that’ll end up sitting around collecting dust.
This kit includes true mil-spec hardware so you can be confident that you’re building on a solid foundation.
