Give your 20-gauge shotgun work the precision it deserves with the Clymer BUSHING, 20 GA, .614" (15.6MM) – B614X1 / B6141. Designed as a shotgun bronze bushing for professional gunsmiths and serious hobbyists, this bushing is engineered to perfectly support Clymer shotgun barrel facers and other bushing-guided tools in 20-gauge barrels with a .614" (15.6mm) bore.
Whether you’re truing a muzzle, cleaning up damage, or performing advanced barrel work, this .614" bushing helps your tools stay centered on the bore, not the outer barrel profile—so you get straighter cuts, more consistent crowns, and more professional results.
Precision Fit for 20 Gauge .614" (15.6mm) Bores
The Clymer 20 GA .614 (15.6MM) Bushing is specifically dimensioned to fit 20-gauge shotguns with approximately .614" bore diameter:
When your bore measures around .614", using the correctly sized bushing is critical to keep your facing or cutting tool perfectly aligned with the bore axis—especially important with tapered or non-uniform barrel exteriors.
Bronze Construction – Tough on Work, Gentle on Barrels
Like the rest of Clymer’s shotgun bushing line, the B614X1 / B6141 is made from high-quality bronze, chosen for its ideal performance in precision alignment applications:
Bronze material resists wear from rotating tools and repeated installations
Softer than barrel steel, helping prevent galling, scratching, or scoring inside the bore
Provides a smooth, stable bearing surface for barrel facers and other guided tools
That means you get a bushing that’s tough enough for daily shop use, but still kind to the inside of your customers’ barrels.
Part of the Clymer Shotgun Barrel Facer & Bushing System
This 20-gauge .614 bushing is one piece of Clymer’s modular shotgun barrel-facing system, which uses interchangeable bushings to adapt a single tool body to many bore sizes:
Works with Clymer shotgun barrel facers and other compatible guided tools
Lets you move quickly from one gun to another by simply swapping bushings
Ensures your tool always tracks the true centerline of the bore, not a possibly off-center outside diameter
If your shop sees a mix of 20-gauge guns with slightly different bore diameters, a dedicated .614" bushing is a must-have for precise muzzle work.
Ideal for Muzzle Facing, Crown Truing & Barrel-End Repairs
A correctly sized bushing like the B614X1 / B6141 plays a critical role in:
Muzzle facing and recrowning after cutting down a barrel
Cleaning up dings, dents, or uneven factory crowns
Ensuring that any barrel-end work is square and concentric to the bore
By supporting the tool in the bore itself, this bushing helps you deliver the kind of results that improve pattern consistency, accuracy, and overall shotgun performance.
Compact, Shop-Friendly & Easy to Organize
Like other Clymer shotgun bushings, the 20 GA .614" model is:
Small and lightweight, easy to store in a drawer or bushing rack
Quick to install and remove when changing between jobs
Clearly marked by size and part number so you can grab the right bushing at a glance
For busy shops, having dedicated bushings for each common bore dimension speeds up workflow and reduces errors.
