Scope mount with built in MOA question

[Vance in AK.]

I am mounting a Vortex Venom 5-25x56 on my RPR Rimfire in 22lr.
I know the rifle has a 30 MOA taper base. The only 34mm rings I can get locally are the Night Force Unimount with a 20 MOA, which will give me 50 MOA built in between the rifles base & the unimount.
Will this cause problems with -0- at shorter ranges?
My ultimate goal is to use the rifle in NRL22 or PRS22. Would I be better off ordering a normal set of my favorite Vortex Rings (1.45")?

50 minutes is a shitload. Wait and buy rings without cant built in. Yes, it will affect ability to get a zero at short range by how much is dependent on a lot of things. The 30MOA base on the rifle (really, on a .22lr? that seems a tiny bit batty) might not help either but if that's true then you can mount the unimount backwards and end up with only 10moa pre-dialed into the system and that shouldn't be a big deal at all.

I think 50 moa might be too much, but worth trying. You can even bottom out elevation then use the reticle hold off for shorter range.
for nrl (all targets under 200 yards ) no extra moa is needed prs goes out further, but I use a 20 moa base on a Kidd with standard rings on a strike eagle, and don run out of elevation at 310 yard.

Thanks guys.
Sounds like I better skip $270 of instant gratification for $150 of doing it right even if it costs me a week of waiting.

I started putting together a bucket list rifle in mid December. It was May before I could even shoot it. Patience is a virtue.

I use a 20 moa base, with Burris XTR rings with with 30 moa in the rings. If what your are using is too much, then want be able to get 50 yds. The XTR rings have from 0 moa to 40 moa. You can do anything you like.

85 MOA total travel is 42.5 up and 42.5 down on a flat rail.

or saying....

42.5 Useable travel and 42.5 Un-Useable travel on a flat rail.

there are some +/- error there but as a general guideline that is the case.

moving your zero down 50 MOA from the mechanical center of the travel means you cannot zero at that same initial distance.

I would not do a 50 MOA offset in this instance.

But maybe your application is only shooting farther out. If so....you could use the 50 and zero further away intitially.

But I wouldn't want to zero further out than 50yds with a 22LR personally. Holding under sucks most of the time.

I had the same scope and same rifle and used Arken Halo rings in 1.26” and it cleared the hand guard. But just barely.

Halo Scope Rings

ARKEN OPTICS Halo Series billet precision scope rings are CNC machined from 7075 aircraft-grade aluminum that have ZERO tolerances for errors in any conditions.

Thanks guys. I have an extra high (1.5" set of MDT rings on the way. Should be here in Alaska by Thursday or Friday.
