Hello, my first time here and my first rifle, well, second, my first was a Remington single shot .22 53 years ago.
I've bought the A17 with the heavy barrel, a Vortex Diamondback Tactical FFP 4x16. I want to target practice. I've seen that precision rifle competitors sometimes use a 20 MOA rail to mount the scope on, so as to make better use of the lower part of the elevation adjustment, when they are shooting a long way.

I just don't know if it makes sense to replace the stock mounts that came on the A17 with a 20 MOA Picatinney rail. The .17 HMR is not reaching as far as those long range shooters. But it would seem the principle is the same, so it sorta seems like it's a fine thing to try.

Any reflections on that?

Thanks.
