My 6.5 build with all the tools to do it all said and done minus the scope was about 1300 bucks. Used a criterion barrel, hs precision stock in a model 12 savage action. My first scope on it was a used vortex ps-t gen 1 that I bought used off a member for 550 bucks.
Ive since then added a muzzle brake, upgraded the stock to a mdt xrs chassis, and upgraded the optic to a vortex ps-t gen 2 5-25x50.
Good thing about building your own is you can kinda upgrade as you go. Next build for me is to build my 7mm mag into a light weight hunting rig with a fast twist and long throat.
