High-quality reamer made by Dave Manson. Lets you easily add some choke constriction to a shortened or standard length barrel without threading or altering the actual choke. Just stop reaming 2" to 3" short of the muzzle and the difference in diameter between the bore and the muzzle is the degree of choke. Tightens chokes on barrels that are too thin for screw-in tubes. Plus, full-length back boring can restore the interior surface of rusted and pitted barrels to "like new" far more quickly than polishing or stoning. Mfg: Manson Precision SPECS: M7 high speed steel. 5" (12.7cm) long with eight straight flutes. 12 gauge only.
