Solid piece of equipment! - Guntec USA AR-15 Buffer Tube For Sig Sauer SB15 Stabilizing Brace

Good pistol tube! Same length as the MI tubes but cost is a little less. Made in the USA, ceracoat version is holding up well to average use, had to use a piece of electrical tape to snug up the SB 15 brace but it was a non issue and recommended by the folks at SB tactical.
