Green Mountain 18" Ruger Precision Rimfire barrel Fluted w/Muzzle Threads

The Green Mountain 18" Ruger Precision Rimfire barrel Fluted w/Muzzle Threads is a precision-engineered replacement barrel designed for competitive shooters, precision riflemen, and serious rimfire enthusiasts who demand match-grade accuracy. Built specifically for the Ruger Precision Rimfire platform, this barrel addresses the core requirement of any accuracy-focused build: a high-quality barrel with tight tolerances and superior shot-to-shot consistency.

The 18-inch length provides an optimal velocity-to-handling tradeoff for .22 LR ammunition, while the integrated muzzle threads (standard 1/2x20 TPI for rimfire applications) allow direct mounting of suppressors, compensators, or thread protectors without adapter sleeves. The fluted design helps reduce overall weight while maintaining rigidity, which is essential for precision shooting where barrel harmonics can influence accuracy.

This barrel is ideal for those running competition matches, conducting load development, or optimizing a dedicated training rifle. At 2.26 lbs, the barrel weight is competitive with other precision rimfire offerings and won't shift your rifle's balance excessively when paired with quality furniture.
