I'm new to this game, so far have a G2 with 2 barrels, 44MAG and 22 LR match, have a .17HMR and HM2 in the works. I went with the Maxima QD rings and the Maxima bases. The rings and bases seem to be HEAVY DUTY, and just plain HEAVY for that matter, I'm pleased with them even though they were pricey and overkill for at least the rimfire setups.
I went with the Maxima medium height QD rings b/c I currently have one variable scope that I wanted to be able to move around for doing accuracy testing & load development with. Once I am happy with a .44 load, will probably mount a Leupold 2X on it with the plain jane maxima rings.
