Geissele Buffer Tube by Jonathan White, Verified Owner, March 5, 2021
Great mil-spec buffer tube. Fit and finish was exactly what you’d expect with the Geissele name. The fact that it comes with an end plate and castle nut is a big plus. It’s worth the money. Period. What are you waiting for? Just buy it already.
