I have a Vari X III in 1.5-5 on my 1895G with the DRC large loop lever, and Wild West Happy trigger, and their one piece ejector. I stripped off the iron sights, filled the two front sight screw holes with filller plugs, and a Marbles dovetail filler for the rear sight. Sweet set up. I shoot 350 Hornadys or Kodiaks under 47 grains of RL-7, or 420 grain or 550 grain hardcast with H-322.
I've converted three huntin buddies to this set up and we've dumped several half ton full of deer and bear with these set ups.
