LRI Barrel Polishing Cassettes
A variety of methods are used to bring up the finish of a rifle barrel. The method we've relied on for over 15 years is the barrel spinner. When used with a vertical belt sander/grinder, a mirror finish is obtainable very quickly. The primary advantage of our system is residue from abrasive belts are kept far, far away from the precision bedway surfaces on equipment like lathes and mills.
Second is time; Once fluent with the procedure, polishing a barrel becomes a very quick process.
LRI's cassettes are 100% CNC machined from 6061 T6 billet bar stock. Like a top quality wrench, they are ergonomically profiled on all surfaces to mitigate user fatigue from commercial use. Cassettes slip onto 1" box steel or aluminum tubing. (not included) and are fitted with sealed bearings. Barrel retention centers are O'ringed so they stay put and are made of Delrin so they'll never mark up a delicate target crown on a barrel. (replacements available separately) One cassette is fitted with a convenient rapid adjustment, multi position lever so that setup can be completely "tool free".
These cassettes are made with the professional user in mind. They provide an expedient means of bringing a barrel to the desired surface finish and are designed to last for years in the commercial environment.
