Bring professional consistency to shotgun choke work with the Gilchrist Precision Choke Reamer (UPC: 736681500002)—a specialized gunsmithing tool designed to help produce accurate choke-bore sizing and a clean internal finish when cutting or refining choke dimensions. Whether you’re a working gunsmith, a well-equipped shop, or an experienced DIY builder with the proper fixtures and measuring tools, a dedicated choke reamer supports controlled, incremental material removal—helping you reach target dimensions with repeatable results.
If you’re searching for a Gilchrist choke reamer, a precision choke reamer tool, or 736681500002, this is the type of tooling used for careful choke-related barrel work where fitment, uniformity, and finish quality matter.
What a Precision Choke Reamer Is Used For
Choke work is one of the most detail-sensitive areas of shotgun barrel service. A precision choke reamer is commonly used to:
Size a choke bore toward a specific target diameter (job dependent)
True and refine an existing choke section for better uniformity
Support choke tube–related barrel work where correct geometry is required
Correct minor irregularities in choke area dimensions
Create a smoother, more consistent interior surface in the cut area
Because choke dimensions influence pattern behavior and choke tube fitment (where applicable), accuracy and repeatability are essential.
Why “Precision” Matters in Choke Work
Choke diameter, concentricity, and surface finish can all impact results downrange. When used correctly, a purpose-built choke reamer helps promote:
More consistent choke-area dimensions
Better repeatability from barrel to barrel (in shop settings)
Cleaner interior finish compared to improvised methods
A more controlled workflow—cut a little, measure, repeat
Reduced risk of over-cutting by allowing careful incremental progress
The reamer isn’t a shortcut—it’s a tool that supports a disciplined, measurement-driven process.
Built for Controlled, Incremental Material Removal
A key advantage of a dedicated choke reamer is control. Proper choke work generally involves:
Conservative cutting passes rather than aggressive removal
Frequent measurement with bore gauges or internal micrometers
Clearing chips often to prevent scoring
Using proper cutting oil appropriate to barrel steel
Maintaining alignment to help ensure concentricity
This controlled approach is how professional shops achieve consistent, predictable results—especially when working toward precise final dimensions.
Ideal for Shops and Experienced DIY Gunsmithing Setups
The Gilchrist Precision Choke Reamer is relevant for:
Gunsmithing shops performing choke sizing and barrel service
Experienced hobbyists with the right measuring tools and fixtures
Shotgun barrel projects where choke geometry needs refinement
Training environments where choke reaming is taught properly
Tooling inventories supporting repeatable choke work across multiple jobs
If your work involves choke modifications or choke tube-related processes, a dedicated reamer is a fundamental tool category.
Best Practices for Use (Non-Promotional Guidance)
To achieve the best outcome and protect the barrel:
Verify the intended final dimension before cutting
Measure frequently and advance slowly
Use appropriate cutting oil and keep the tool clean
Maintain alignment and steady feed to reduce chatter
Inspect and clean the bore thoroughly after reaming
If you are not trained/equipped for barrel work, use a qualified gunsmith
Choke reaming is irreversible—proper measurement and technique are essential for safe, correct results.
