Micro Adjustable Reamer Stop Kit - (MARS Kit)

This 8 piece kit makes chambering a barrel easier, and is for use by experienced gunsmiths and machinists only. Detailed instructions are included.

Co-Designer Nat Lambeth reports: The photo shows a new tool called the Lambeth/Kiff Micrometer Adjustable Reamer Stop (Patent Pending). This is a add-on device that controls the depth a reamer can cut. It uses the reamer itself as the micrometer pinion and the barrel tenon face as the anvil. It does not matter where the tail stock or carriage is located, it measures off the reamer. It functions with a floating reamer holder too. These new Micrometer Reamer Stops have 25 indexing marks and will allow for .001″ adjustments. The gunsmith can preset the Micrometer Adjustable Reamer Stop to about .020″ out and ream without worry. Then re-measure, adjust once, and make the final cut right on the money.

Our Reamers are individually hand-stoned to cut smooth and chatter free. Made to SAAMI specifications or custom specifications for standardized cartridges and to the current industry standard for popular wildcat cartridges. They feature removable pilots that are held in place with a screw and a 3/8" square drive shank for use that may also be used with a tap wrench. Reamers include one bushing of nominal bore diameter.
