I bought the Manson kit from Dave at the last SHOT show, and use it for situations where I can't get the barrel in the lathe, like with revolvers and rifles that don't come apart easily. It works very well with two observations. The pilots are a bit fragile so be careful with them. They work fine, just treat them gently. The other is some barrels refuse to be cut without leaving a burr. Most work fine, but some steel just has to leave a burr, so in those cases I lap out the edge with a brass ball on a stick run by a drill motor. So, my recommendation? For one gun done at home it is a lot of money to get you where you want to go. But for a shop like mine where crown jobs are done every day, it is quite useful and will pay for itself in short order. Oh, he also has pilots for shotguns so it works beautifully for shortening barrels on those too.
