Ruger SR22 - what height for a riser for mounting optics?

[jtiu]

hi!

I finally got around to getting a basic Tasco 2.5-10x 42mm scope for my ruger sr22.

The guy recommended I get a riser to install the picatinny rail and then install the scope onto it. Indeed, the scope is a bit low without one and this seems to be a common problem for the SR22.

For those of you who have mounted a scope on the SR22, what height riser should I use?
I was looking on amazon for example and found half an inch or one inch. is half an inch enough...?

0.5 inch riser

1 inch riser

I just measured mine, just a hair under 1".

Or you could get high scope rings for about the same price

I used high scope rings worked fine. (1")

Keep the optics as low as possible and as close to the centre line of the borr as posdible
