The Bore Tech 22Rf Bore Guide is the chamber-protection bore guide specifically machined for CZ 452, 453, and 455 .22 rimfire rifles. The guide seats in the receiver and channels the cleaning rod through the bore without letting the rod contact the chamber walls or throat.
Critical for serious CZ rimfire shooters — chamber-throat wear from cleaning rod contact is the leading cause of accuracy loss in precision rimfires. The Bore Tech guide eliminates that wear path entirely. Made in Pennsylvania by Bore Tech for precision rimfire owners.
Bore Tech is a Pennsylvania-based maker of professional firearm cleaning solvents and bore tools. The Eliminator, C4 Carbon, and Cu+2 Copper solvents are the standard chemistry for competitive shooters and benchrest rifle owners — non-toxic, ammonia-free formulations that out-clean traditional petroleum-based solvents.
