Certainly low or medium height. I like the low rings because the ARMS18 is low to begin with and that allows a low cheek riser/position/cheekpad/cheekweld. With the Bushy 3200 Elite 10 x 40mm mildot, the rear bell might conflict with the rear sight aperture. Simple fix. Pull off the rear sights....
Medium height, if you don't want to pull off the rear sight to alleviate this rear eyepiece bell contacting the top of the rear sight aperture.
I'm a Millett Angle-Loc fan because I've learned how to use the windage adjustable allen screws. That being said, many people hate the darn rings and then post them up for sale on the EE Forum. I come along and buy them. Life is good.
MysticPlayer is a Burris Zee rings fan and he swears by them. Choose your poison! Just take a strip of electrician's (black is my favorite) tape to line the inside of the rings before installing them. This avoids/prevents any scope tube scratching/marking/scarring.
slushee a shop like Epps have lots of inventory for you to bring the combination up to Orillia and try things out before buying.
Hope this helps,
Barney
