Product Description
The J.A.C.K. (Just Another Carbine Kit) is designed to provide a solid foundation for your next build by using high-quality, US made components. The barrel and gas system are the heart of your rifle and TNTE takes the worry out of your build by supplying you a DIY framework that can be customized to your preference. We pin the gas block, mount the barrel to the upper receiver and install the gas tube. We recommend you lock tite the set screws after you receive the upper.
