Grayboe Universal Mini Chassis For Tikka T3 Short Action Black
The Grayboe Universal Mini Chassis for Tikka T3 Short Action is a precision bedding block that transforms how you shoot multiple rifles and calibers from a single stock. This billet aluminum chassis accepts your Tikka T3 short action rifle and bolts directly into Grayboe's Flagstaff Core or Renegade 2 stocks, letting you swap rifles and calibers without changing your primary shooting platform. It's a smart solution for shooters who want modularity without the complexity—or the cost of buying separate stocks for each rifle.
Built from T6 6061 billet aluminum and finished in Cerakote black, the chassis weighs just 14 ounces and is engineered for repeatable accuracy and reliability. The UMC secures to your stock via two provided screws, creating a rock-solid mechanical connection that seats and locks your rifle firmly in place. Magazine compatibility is straightforward: the chassis accepts standard AICS magazines, so your ammo and feeding stay consistent whether you're running short-action cartridges with standard short mags or longer rounds with 3.850-length AICS mags.
The optional adjustable magazine release lever gives you fine-tuned control over mag height, offering up to 0.080" of adjustment for dialing in perfect cartridge feeding—especially useful when load development or ammo transitions demand precision. If you're a serious shooter who works with multiple rifles, platforms, or calibers, the Universal Mini Chassis eliminates the need to juggle separate stocks and streamlines your setup from the range to the field.
