Sweet looking build! For the scope, is that rail one of those single contact point jobs? If so, how do you like it? I tried one, but recoil kept me busy re-adjusting it, lol.
I got it from Combat Hunting
Close up image during the build so you can see the way it is sandwiched in there.
The ATI one uses a single pin too but doesn't have that center block to sandwich in the bracket and I've heard it is looser.
