Known for producing high quality AR accessories, Phase 5 manufactures the Hex-2 buffer tube specifically for pistol builds. This receiver extension is CNC machined from US certified 7075 billet aluminum and can be used with the included nitrile foam pad or a pistol stabilizing brace from SB Tactical. The round rear of the tube meets the hexagonal section and is designed for braces that accept a 1.2" round tube. It is not compatible with adjustable braces such as the SBA3, SBA4, or SB Tactical PDW. Phase 5 and SB Tactical worked closely together to develop this high-end system component. This package comes in at 7.4" overall length and a total assembled weight of 11.5 oz.
