You won't be disappointed! You have enough internal adjustment for the 1K+ yard shot but highly recommend a 20 MOA base per an optics SME's advice ...
What do you think of the reticle on the 4-20? I believe that they only offer one on this model.
I'd rather have the moa reticle that is available on the 5-25.
I just don't care for BDC reticles at all.
