CZ 457 Bore Guide – Key Benefits
Fits CZ 457, 455 and 452 actions .22lr and .22 WMR
Protects the bore and rifling: The primary purpose of a bore guide is to hold the cleaning rod centrally within the bore, preventing it from rubbing against the sensitive chamber throat and the rifling. This minimizes mechanical wear and potential damage that could degrade accuracy over time.
Prevents damage to the muzzle crown: When cleaning from the muzzle end (as with some firearms like M1As or muzzleloaders), a bore guide or muzzle protector is essential to preserve the barrel’s crown, a critical feature for consistent bullet flight and accuracy.
Keeps solvents out of the action: Bore guides, especially those with O-rings and solvent ports, create a seal that stops corrosive or harsh cleaning fluids from leaking back into the action, trigger group, or magazine well. This prevents rust and damage to internal components and the firearm’s finish or bedding.
Ensures proper alignment and force: By keeping the cleaning rod straight and aligned, a bore guide ensures the cleaning force is directed effectively down the barrel, reducing the chance of bending or bowing the rod and gouging internal parts.
Improves cleaning consistency: A bore guide makes the cleaning process more consistent and efficient by guiding patches and brushes smoothly through the barrel.
