Takes less than an hour to fit it, small shim in front of mag box and removal of a little material in front of rear action screw so that the "L" bracket fits and possible sanding of barrel channel,that depends on the contour of your barrel.Now all this is only needed if you own a centerfeed.
Stocky's may have it in the Tundra but colors are limited.
You can also look here http://www.gunpartscorp.com/catalog/...px?catid=12160 these are factory stocks and colors are very limited but there are long action ones you just have to look through them.
