Barrett M82A1 Question about Picatinny Rail. Is there Cant in the Top Scope Rail?

[338LM_Sniper]

I just picked up a New Barrett M82A1 and was wondering if there was any Slope or Cant in the Top Picatinny scope rail, and if so just how much MOA Cant?

I am going to mount a scope with a Spuhr Mount and my Spuhr Mount already has 20 MOA of Cant, so if the Picatinny Rail has Cant in it I will need to consider a Spuhr Mount with 0 MOA Cant.

Thanks in advance.

The Googler says 27 MOA built in...

If you use your 20 moa sphur you probably will not be able to zero at 100 yards depending on your scope elevation range. You will be like a foot high at 100 yards

Turn your 20MOA mount around. Then you have a net 7MOA to compensate for.

Confirming that is correct. I own one.

I actually did that when I was first messing with my ERA-TAC adjustable mount lol. Caught it on my own before anyone could laugh at me.

It’s what I do on my 107A1. Same 20 MOA rail. Had a 30 MOA Spuhr. 50 MOA was ridonkulous, so now I have a -3MOA setup.

You know something is wrong when your rear ocular barley clears! My setup is capable of -43 MOA (27-70). Perfect for shooting down Chinese "weather" balloons.
