Overview

The Phase 5 Weapon Systems Rifle Length Mini Stock Assembly (RMSA) is a fixed stock kit designed for AR-15 and AR-10 platform systems. The assembly includes a Universal Mini Stock (UMS) machined from 6061-T6 aluminum and a rifle-length HexOne buffer tube cut from 7075-T7 aluminum. The HexOne tube features a hexagonal design that offers increased thickness and rigidity compared to standard mil-spec receiver extensions.

The UMS is also compatible with other buffer tubes, including mil-spec carbine receiver extensions and most round tubes.
