Grayboe Universal Mini Chassis System Inlet Short Action Howa Black

Overview

The Grayboe Universal Mini Chassis (UMC) system in black is engineered to provide a versatile bedding block solution for Howa 1500 short action rifles. Designed to drop into Grayboe Flagstaff, Core, and Renegade stocks, the UMC allows shooters to interchange different rifle brands and calibers within the same stock platform. Weighing 14 ounces, the chassis is precision-machined from T6 6061 billet aluminum and features a hard-coat Type III anodized or Cerakote black finish. It anchors securely into the stock using two included screws. The unit accepts all AICS magazines without requiring bottom metal, with magazines clicking directly into the bottom of the chassis. Additionally, it features an optional adjustable paddle-style release lever that provides 0.080 inches of magazine height adjustment for optimal cartridge feeding.
