The Phase 5 Carbine Mini Stock Assembly (CMSA) is a combo kit featuring our Universal Mini Stock (UMS) mounted on our Hex One buffer tube for an excellent compact fixed stock solution. The UMS is also compatible with a number of other buffer tubes, including Mil-spec carbine receiver extensions and most round tubes, it was designed to complement the sturdy HexOne buffer tube.The UMS and Hex One are precision machined in house from USA sourced raw billet aluminum.The Hex One buffer tube is cut from 7075-T7 and the UMS is 6061-T6.

The HexOne buffer tube features a hexagonal design that is much thicker and rugged than a mil-spec receiver extension tube making it perfect for 5.56 NATO, 300 BLK, or even calibers like 7.62×39 and.308 (If you use this on a .308 weapon, you will need a .308 carbine buffer and .308 carbine spring). It will also work with pistol caliber carbines such as 9mm, 40 S&W, and 45 ACP, but you may need a different buffer and/or spring.

The Hex One and UMS undergo a rugged tumbling process that further strengthens the exterior of the parts while leaving the surfaces smooth and snag free.
