    Best price I could find AND buffer/spring included. Everything I needed to complete the rear of my pistol lower for one low price of $120. Was also gladly surprised it came locally from Ohio, was still worth it w the sales tax. Highly recommended!

    Excellent offering from SB Tactical to finish off your pistol build. My product works and functions as advertised. However, there was damaged plastic at the base of the position adjust lever. This didn’t come from shipping as B.Kings properly cushioned and packaged my entire order to include BCG, Pistol brace, charging handle and Aero LPK. Not sure how to explain that. Product does work despite the plastic damage.

    The service was absolutely amazing. By far the best price anywhere on the internet. The threads on the buffer tube were nice and clean and had no problem threading into my spikes lower. B. King’s has become my new favorite website. I plan on using them to finish out my build.
