Help on choosing front iris diameter.

Hello everyone!
I have a FWB P70 with M22 front sight and a Anschutz mod.1907 with M18 front sight.I want to buy a adjustable front iris to fit both and the solution is that P70's sight has a threded collr that can take a M18 iris.
So by buying a M18 iris will fit both my rifles.
The question is,will a M18 on M22 can cause me any problem?I will not have front sight length problem.Do you think that it could cause problems while aiming?
Thank you!

Gehmann make a threaded step up collar so their 18mm iris fits the 22mm tunnel. This way you can use the same iris on both guns.

Hello peepsight!
I know that collar,it is part no 538.
But I dont need it because P70's front sight has a threded collar that can take a M18 iris.
So I guess I will not have problem with aiming.
Thank you peepsight!
