any advice mounting 2 piece weaver bases to ensure their straight before mounting rings. its only for a 22 so recoil isn't an issue, but i want it to be a nail driver. or do i spend the money for a 2 piece leupold mount. it came with the cheap 2 piece weaver bases so i already have those and rings are fairly inexpensive, i cant find any one piece bases for the discontinued tc 22 classic
