I converted my 10/22 to a 17HM2, I guess you could call it tactical. The only stock piece left is the receiver housing, lol.
http://www.eabco.com/102201.html I used that place for most of my parts and Midway for the rest because they had some closeout sales.
I duracoated it WWII OD Green as well. I plan on rehitting it with some Duracoat again, I want every single piece WWII OD Green, stock and all.
I have a lot of money wrapped up into it but it's worth it, it's the funnest gun to shoot on the planet, IMO.
As far as advice, your first mod should be the power custom hammer and sear kit, yes, even before the barrel or stock, the factory trigger is that horrible.
