MOA for the rail and scope mount

[thexman]

I saw in rifle and scope mount description it normally mentions it's 0 or 20 MOA rail or mount.

I am wondering if that means the picatinny rail and scope mount elvation can be adjusted to up to 20MOA?

Thank you.

That means it would have either 0 or 20MOA of forward cant built into the base or mount.
Freeing up some of your elevation adjustment in your scope for longer range shots.

Thanks, so it’s a fixed built in feature, not something I could adjust right?

In general they are a fixed amount and not something that is user adjustable but I do believe there are some high end mounts that are I've just never actually used one or had any need.

They’re generally fixed, but Era-Tac does make an adjustable mount: https://www.eurooptic.com/era-tac-adjustable-inclination-mounts.aspx

Can I say the 20MOA rail or the scope mount/rings is making the scope pointing 20MOA down (if the barrel direction consider is horizontal, the scope direction is pointing like a down hill) to give the scope elevation adjustment additional 20MOA up when shooting longer distance?
This is my understanding after reading this article: https://warnescopemounts.com/20moa-explained/

That's correct 20moa of forward cant
