20" will get you as far as you will ever need to, can buy a mount with cant built in it.Well, y'all are a persuasive bunch. Won a Tikka CTR in 20 inch stainless on GunBroker. Anxiously waiting for FFLs to do their thing. I know 24 inch is preferred, but for my immediate needs 20 should be fine and maybe I'll get a suppressor someday.
When I was researching the Bergara HMR it didn't come with a pic rail for scope and everything I read said get a 20 MOA. The CTR has a rail but doesn't look like a 20MOA. Do folks replace it or go with taller rings?
