The Chadwick & Trefethen "A" Adjustable Reamer is a precision gunsmithing tool engineered for shooters and gunsmiths who need reliable choke reaming across multiple shotgun gauges. This adjustable reamer handles 10, 12, 16, 20, and 28 gauge shotguns, plus .410, making it a versatile addition to a reloading or gunsmithing setup. The tool also excels at fitting 1911 Auto barrel bushings—a critical task for anyone working on or customizing that platform.

The blade angle is specifically designed to eliminate chatter and produce clean, controlled cuts with every pass. This thoughtful engineering reduces the frustration of tearout or uneven reaming, which matters whether you're working on your own barrels or managing precision fitment for clients. For best results, Chadwick & Trefethen recommend pairing this reamer with their Barrel Hone and Caliper as part of a complete reaming and finishing process.

If you're serious about shotgun choke work, 1911 builds, or general gunsmithing projects that demand repeatability and finish quality, this adjustable reamer is built to deliver. It's the kind of tool that rewards technique and attention to detail—and punishes poor practice with visible results, which is exactly what you want in a precision gunsmithing instrument.
