Thompson Center Arms 4080R Venture 3+1 243/6.5Crd/7Mm/308 Black Steel

The Thompson Center Venture 3+1 magazine is a factory-original polymer magazine engineered to feed .243 Winchester, 6.5 Creedmoor, 7mm, and .308 Winchester ammunition reliably through your Venture rifle. Whether you're hunting medium game or running drills at the range, having a dependable spare mag—or backup capacity—keeps you in the field longer. Thompson Center builds these to the same exacting tolerances as the magazines that ship with Venture rifles, so you know they'll perform when it counts.

Polymer construction keeps weight minimal without sacrificing durability. The 3-round capacity strikes a practical balance: it's compact enough to stow in a pack or vest pocket, yet gives you a reload's worth of ammunition on hand. The straightforward design means nothing to break, adjust, or fiddle with—load it, insert it, and trust it to work.

If you own a Venture or are considering one, having a spare magazine is sensible insurance. Magazines wear out or get lost. A factory replacement ensures perfect fit and function with your rifle, no questions about compatibility or reliability. Stock one or two for extended hunts or range sessions.
