I believe dogshooter is correct even though TC denies it. I bought a 1.25-4 a couple of year ago. It looked just like a tasco with a hole drilled in the turret that was labeled nitrogen fill. Never seen this on any other brand scope. Asked T/C and they denied it but it looked like a Tasco to me, turret caps, everthing. I sent it back and traded it for a Burris because I was not going to pay $225 for a $125 scope.
I do have a T/C 2-8, and it looks nothing like that 1.25-4 did. They said they have different companies make their scopes but Tasco is not one them. I doubt that to be true.
