Very nice buffer tube - Strike Industries Carbine Length Pistol Receiver Extension

These are some of the best buffer tubes offered for AR pistols. The fit and finish are perfect. They also have very nice looking chracteristics. The bottom is also dimpled to keep your pistol brace set screw in place. Pair this up wiht the stike industries brace and you will have a very nice set up..

Want to thank Optic planet for their great customer service. I had an issue with the shipment, not OP fault, and they made it good.
Thanks for everything OP.
