Jeez-o-pete! All this talk of heavy barrels - my V22 repeaters weigh 13-13.5lbs, with 21"-23" bbls in contours no heavier than Rem sendero, in Manners PRS1T stocks, with no frickin' weights attached. Balance isn't as important to me as building a rifle I can pick up and carry to the firing line without causing major pain in my worn-out shoulders with torn rotator cuffs...if I had to safely climb up onto the rooftop prop with a rifle weighing 20-22lbs, I'd have to have help getting up there - let alone managing to get back down quickly enough to shoot the rest of the stage on the side rests & shooting ports under the rooftop...lol
