By the time you buy quality parts, include your valuable time, you may save a few bucks, the real advantage is that JP will take care of you if you have an issue.
Have been shooting one since 6/27, was competitive out of the box, flawless function from the first round, have one on order for the Lady, the weight or lack of not an issue, I have no plans to win national championships, and until you get up there in the ranks you won't know the difference. There is nothing more delightful than having an instrument that functions flawlessly at a match, there is nothing worse than a piece that frustrates you and wastes you time and entry fee ?
The only downside is that if you don't perform well, you can't blame that rifle ?
