The Universal Mini Chassis (UMC) fits into the Flagstaff, Halo, Core and Renegade 2 stocks. Your rifle bolts to the UMC, then you bolt your rifle with the UMC on it, into your Grayboe stock. With a UMC inlet for your rifle, you can interchange different rifles & calibers into the same stock.

plug and play system

Shoot multiple brands of rifles and calibers out of the same stock. Short or long action, Remington or Howa, it doesn't matter. All Universal Mini Chassis (UMC) fit the stock the same. If we have a UMC for it, it fits.
