Customers and practitioners that are in need of having threaded muzzles or barrels cut and crowned may contact J.C.Adler, LLC, for this process.
All barrel treading is lathe turned, having been dial indicated, from the bore diameter, to assure concentricity. Whenever possible, tapered bore mandrels are used to indicate the lands within .0003″. For barrels that can not be chucked, at the muzzle, custom piloted bore guides are used to center the bore.
Muzzle devices that need to be timed, such as sound suppressor mounts and removeable/indexable brakes,will have the barrel shoulders machined perpendicular to the bore. Shims and crush washers are not used in this process.
Pistol and revolver barrels are crowned and/or threaded with proprietary lathe tooling. Custom internal mandrels are turned to run the entire length of the bore. This insures superior accuracy and guarantees, near perfect, concentricity of any muzzle device.
J.C.Adler,LLC will also, on request, provide a simple “cut and crown” process for rifles and shotguns that exhibit damaged crowns or require cutting down barrel length. This process is a low cost option for customers that are not seeking hyper accuracy for their sporting long guns.
Cutting, crowning and threading services are usually completed and returned within 2 weeks.
