Thompson Center Venture Magazine for .22-250
Thompson Center chose polymer construction for good reason. It weighs less than metal alternatives, handles impacts better, and resists moisture and temperature swings that would damage steel. Field-tested and proven on countless Venture rifles, this magazine has earned a reputation for reliability in all conditions from prairie dog country to late-season hunting in challenging weather.
Built to Integrate Perfectly
The magazine latch is integrated directly into the magazine itself, eliminating extra parts and keeping costs reasonable while maintaining a clean, functional design. The single-stack layout fits naturally in the Venture platform and feeds rounds smoothly thanks to a heavy-duty internal spring and follower system. The 3-round capacity meets the most common hunting and range scenarios for this caliber.
Simple, Effective Design
