20, 30, 40mm Rail
Well, to confuse the issue most bases are thicker at the rear as the back of the receiver is usually flattened somewhat. What kind of rifle is it on?No numbers on the base but definitely thinner toward the front and thicker at the rear. I tried to measure the difference with calipers but it was too tight. So… if I get a 0 MOA base I should be ok???
Thanks again for everyone’s help!
Excellent! That's most likely going to be the issue then. You just need to figure out how the zero stop works. Hand Skills will probably show up and he can help you with that better than I can or you might be able to find some instructions online.It’s on a Howa 1500. And it does have the locking target turret like the circular picture.
