Thompson Center Arms Venture 7mm Rem Mag/300 Win Mag 3-Rd Black Steel Magazine

The Thompson Center Arms Venture is a proven American-made bolt-action hunting rifle, and this factory OEM replacement magazine (MPN 4100R) is built specifically for the rifle's long-action 7mm Remington Magnum and 300 Winchester Magnum chamberings. Constructed from black steel for dependable feeding, this detachable box magazine fits the Venture's magazine well so you can quickly swap a spare or change loads in the field.

The 3-round box delivers the standard 3+1 capacity of the long-action Venture - three rounds in the magazine plus one in the chamber - making it well suited for hunting, range sessions, or simply keeping a backup on hand. Because the same long action handles both 7mm Rem Mag and 300 Win Mag, a single magazine works for either caliber when fitted to the appropriate Venture rifle. This is the genuine factory part from Thompson Center Arms, not an aftermarket clone.
