Grayboe Flagstaff Stock: The Ultimate Modular, Rugged Choice for Backcountry Shooters

INTRODUCTION: BUILT TOUGH FOR THE BACKCOUNTRY

Grayboe's new Flagstaff stock embodies rugged reliability. Molded from impact-resistant polymer, this stock is lightweight, weather-proof, and trail-tested—designed to endure harsh environments season after season. It ships in 48 hours or less and comes backed by a lifetime warranty.

MODULAR MINI CHASSIS SYSTEM: ONE STOCK, MANY RIFLES

The Universal Mini Chassis (UMC) system makes the Flagstaff remarkably flexible. Bolt in multiple actions—short or long, Remington or Howa—using the same stock. If a mini chassis exists for your rifle, it works seamlessly. This plug-and-play design means you can easily swap rifle systems without changing stocks.

INTEGRATED M-LOK RAILS AND SLING MOUNTS

The forend features molded-in M‑LOK slots for accessories like Picatinny or Arca rails. Two QD sling attachment points are also integrated—offering secure and quick sling setup for rapid shoulder carry.

ERGONOMICS AND FUNCTIONAL DESIGN

Enjoy traditional feel with modern enhancements:

Thumbshelf and finger groove on the pistol grip ensure consistent hand placement and quick target acquisition.

A molded recoil pad balances muzzle rise while providing comfort.

The forend offers a generous 11.25" length, with textured finger grooves for off-hand support.

The grip sits at a 35° angle and includes texture for a firm hold even in adverse conditions.

AICS MAGAZINE READY (NO BOTTOM METAL REQUIRED)

Flagstaff’s mini chassis acts as bottom metal, so magazines drop right into the stock—no additional bottom metal needed. It supports standard AICS short mags and 3.850" long-action versions.
