looked at a Marlin, brand new bolt action rifle with a weatherproof stock and it cost only $299 at Dick's. Micro-grooved barrel and an adjustable trigger too boot. Darned nice rifle.
My question is why would you go to that much effort to make a rifle when $299 will build you a rifle that is undoubtedly better and has features no available on the Mosin conversion. I bet the builder has more than that in the Mosin since he has done a really nice job.
You have to have a "why" for such work and that much trouble to make a rifle when new ones can be had for such low prices.
