The Grayboe Universal Mini Chassis (UMC) for Remington 700 short action rifles is a precision bedding block that transforms your factory R700 into a modern, magazine-fed platform without requiring extensive gunsmithing. This billet aluminum chassis accepts AICS magazines directly—no bottom metal needed—and anchors securely to UMC-compatible stocks like the Grayboe Flagstaff, Halo, and Core with just two supplied screws. If you're building a short-action hunting rifle, precision bolt gun, or competition shooter and want the modularity and reliability of a magazine-fed system, this chassis bridges the gap between classic Remington 700 ergonomics and modern rifle architecture.
Built from T6 6061 billet aluminum and finished in Cerakote black or hard coat anodized Type III, the Universal Mini Chassis weighs just 14 ounces and seats directly into your stock, creating a rigid, repeatable platform for consistent accuracy. The design works with factory triggers and safeties, though some aftermarket triggers and rifles with large trigger hangers may need minor fitting. Because it interfaces with standard AICS magazines, you can swap between short and long-action magazine lengths depending on your caliber, giving you flexibility as your rifle collection grows.
Installation is straightforward: the UMC simply clicks into place and locks down with the two provided anchor screws. This quick-changeout design means you can swap the chassis between compatible stocks or remove it entirely without permanent modifications to your action or stock. For Remington 700 purists who want modern functionality without replacing their rifle, or hunters and shooters building a dedicated short-action system, the Grayboe Universal Mini Chassis delivers practical modularity backed by solid engineering.
| Rifle Compatibility | Remington 700 Short Action, Remington 700 Clones |
| Magazine Type | AICS (standard short length) |
| Material | T6 6061 Billet Aluminum |
| Finish Options | Cerakote Black, Hard Coat Anodized Type III |
| Weight | 14 ounces |
| Stock Compatibility | UMC-compatible stocks only (Grayboe Flagstaff, Halo, Core) |
| Trigger/Safety | Factory compatible; some aftermarket triggers may require modification |
The UMC is designed exclusively for UMC-compatible stocks. Grayboe manufactures the Flagstaff, Halo, and Core stocks with UMC integration, and these are the stocks this chassis will anchor into. Always confirm stock compatibility before ordering.
No. The Grayboe Universal Mini Chassis is designed for Remington 700 short action rifles only. While it accepts AICS magazines in both standard short length and 3.850" length, the chassis itself is built to fit short-action barreled actions.
No. One of the key features of the Universal Mini Chassis is that AICS magazines click directly into the bottom of the chassis—no separate bottom metal is required. This simplifies the build and reduces parts count.
The UMC is compatible with factory Remington 700 triggers and safeties. Some aftermarket triggers may require modification to fit properly, so if you're using a non-factory trigger, check clearances or contact Grayboe support before installation.
