Which guns come with 20 MOA top rail?

I believe the Priest 2 has it as an option.

UTG makes a 20 MOA adapter and you can find several one piece mounts with 20 MOA off set if you want it for a any gun

That's funny.. I watched the Shot Shot presentation on the new Zbroia PCPs and did an Internet search to see if they had canted / ~20MOA rails, which led me to this thread The sad news is that it doesn't look like they do, but it wouldn't surprise me if they added them to the new lineup when they're shipped  

Sorry for the dumb question, but what is a “20 MOA” rail? I know MOA as a red dot scope term...

I found these explanations:

"A 20MOA base is only needed for certain applications. When a shooter is adjusting the elevation dial on the scope for ranges longer than what the gun is zeroed for, at some point, they will run out of elevation in the scope. In many instances this is around 600 yards, give or take."

"At 600 yards, a 20 M.O.A mount will point the scope down .120” or point the barrel up depending on your perspective. One M.O.A. = 1" at 100 yards or 6 inches at 600 yards. 20 M.O.A. = 200 inches at 1000 yards."

"You should get better cheek-weld with lower rings and better consistency. If you're shooting at 600 yards the MOA of your rail won't matter, but if you want to mess with long range at the range, you may as well get the 20 MOA base. Stretching it out at the range can prove to be very enjoyable."

So... why do our Taipan Veterans' and many others have built-in 20 MOA ? Seems unnecessary for short range equipment.

I have been wondering about this, too.

Math says that 20MOA (.33 deg) will tilt your barrel up 10.37 inches at 50 yards (which is 1800 inches)



Using a 30PFE .22 cal PCP as an example you'd only need about 3 or 4 inches of tilt to be zeroed and optically centered at 50 yards.

So to me it seems that 20 MOA is over kill for a 50 yard far zero which makes me use quite a few clicks of elevation to compensate.



Wouldn't a 7MOA rail be better suited for airgun use?



This would be my personal preference.

My ideal setup would be to have my scope optically centered and zeroed at 50 yards and use the reticle for holds nearer and farther than that.



I ran through this math pretty quickly. Please feel free to correct any errors.



Edit: Forgot about the scope height above the barrel which in my case is 2 1/2 inches.

So 2 1/2 plus 3 = 5 1/2 inches meaning more like 10MOA not 7MOA.

Certainly not 20MOA

The EVOL has 50 moa 

Airguns, by virtue of their lower velocity and power, are commonly shot at very short ranges when compared to long range firearms. Air guns can use the high MOA rails to attain a zero at those much shorter shooting distances without using up all of the available elevation adjustment in the scope. Doesn't hurt to have the scope "closer to optical center" either but I'm not certain how critical that is to function of a quality scope.

Having moa built into the rail allows us to zero the gun at much further distances without running out of scope turret adjustment. It's a nice feature that I'm surprised more manufacturers haven't figured out.

That pellet will have 6 or 7 inches of drop at 50yds. Depends on velocity and BC.

Include the scope height and 20MOA is not that far off.

I'd go with about 15MOA in your case. If the gun were 12fpe, than 20MOA would be about right.
