I own an H&R Handi-Rifle in .223 Rem. It is a good gun and fun to shoot. I am actually planning to get a ML barrel for it when I can start shooting again. If I were you, I would call to make sure you can get rifle barrels for the Huntsman, If no, I would buy the Handi-rifle, in whatever caliber, and then buy a ML barrel for it. That way you can buy other centerfire barrels for it also.
