NBS SLICK SIDE UPPER
Fast shipping 👍 Checked the fit against 2 other 80% lowers builds awesome fit, so tight I don’t need the accu-wedge’s that I have in other 2 builds. Bcg fits perfectly, buffer tube assembly is all good. This is an AR 9 build , still waiting on other parts to complete. So far so good. Awesome prices.
