only use a riser if you need one. If you do, stick with a 1 piece. For most AR uses getting 20MOA or 30MOA built into the riser is enough to get you down at the bottom of your scope's adjustment range. Adding the Burris Zee rings lets you dial that up/down as needed. I'm skeptical as hell about any riser causing scope rotation. Calling BS on that.
