Phase 5 Weapon Systems RMSA Rifle Mini Stock Assembly Black Aluminum for AR15AR10

The Rifle Length Mini Stock Assembly RMSA is a combo kit featuring Phase 5s Universal Mini Stock UMS and rifle length HexOne buffer tube for an excellent rifle fixed stock solution. The UMS is also compatible with a number of other buffer tubes including Milspec carbine receiver extensions and most round tubes it was designed to complement the sturdy HexOne buffer tube. It is precision machined in house from USA sourced raw billet aluminum. The HexOne buffer tube is cut from 7075T7 and the UMS is 6061T6. The buffer tube features a hexagonal design that is much thicker and rugged than a milspec receiver extension tube making it perfect for any of your rifle length AR platform systems. The UMS offers a smaller footprint and bottom curve which makes for a far superior anchor of the stock on the chest. This allows an operator to get in and out of position with greater of ease.
