Mr Magnum Lt 10/22 Bbl 22lr 16.5" Td

The Magnum Research Mr Magnum LT 10/22 Barrel in .22LR with 16.5-inch threaded barrel is a precision replacement barrel engineered for Ruger 10/22 takedown models. Built with patented uni-directional graphite carbon fiber construction, this barrel dissipates heat significantly more effectively than traditional steel, maintaining temperatures up to 43% cooler during sustained fire without affecting zero retention—a critical advantage during extended range sessions or high-volume training days.

The 16.5-inch length balances velocity development with practical handling in the .22LR cartridge, a standard that prioritizes accuracy and low recoil over power. The threaded muzzle accommodates suppressors and other muzzle devices, expanding versatility for both suppressed shooting and sound signature reduction. At 1.63 pounds, the carbon fiber construction delivers weight savings over conventional steel barrels while maintaining rigidity and precision. The takedown compatibility means users can quickly swap barrels for different configurations or maintenance without requiring gunsmith services.

This barrel is ideal for precision shooters, small-game hunters, and trainers who run high-round-count sessions where thermal stability matters. The .22LR platform serves as a cost-effective training tool for shooters developing fundamentals, and the carbon fiber advantage becomes apparent during rapid-fire drills where conventional barrels experience shot-to-shot drift from heat rise. The Ruger 10/22 platform's widespread adoption among military and law enforcement marksmanship instructors makes this barrel a logical choice for dedicated training builds.
