• T/C Dimension (Components)

    Bring every game of North America into play on your hunts with a T/C Dimension Bolt Action Platform. Changing the Dimension's components and caliber-specific barrels takes less than three minutes.

Key to the Dimension’s interchangeability is the Locking Optimized Components (LOC) System. The LOC System consists of a universal stock and receiver that accepts multiple barrels, magazine groups, bolts and bridge scope mounts, and are grouped into four Dimension Caliber Series (color coded and labeled A, B, C and D). Picking out the right LOC system at the store and assembling it at home is as easy as matching the bolt and magazine group to a barrel of the same series. LOC System stocks, receivers, bridge scope mounts and hand tools can be used with any of the Series components.

The specially designed high cheek piece makes shooting the Dimension feel even more natural, aligning your eye properly and evenly to the scope.
