The 460 Rowland® family of firearm upgrades are sometimes copied and feloniously marketed by unscruplious bootleggers right here in America!  And while this can be seen as an endorsement of the Mighty 460 Rowland Ballistics, (“copying is the best form of flattery”), it’s still disappointing to find out that not all intellectual property thieves are Chinese Communists, but that some look and act just like Good-Old-American gun sellers.

So please look for the registered trademark “®”, (and check with 460 Rowland® directly), be sure.
