I've had several guns done by H&M, all came out very nice, it works better on cromoly but barrels need to be broken in before you send them. It also takes a good hour to clean all the gunk out of the barrel after you get it back, some really nasty stuff.
It makes the bolt glide like its on rails and is very corrosion resistant after treatment
