The ARO may not fit in pistol slides cut specifically for Fastfire red dot sights. How do I know which riser mount to get? For modern rifle platforms, we recommend the. 83 Mount if you are running without iron sights, since it puts the red dot at the standard height of iron sights. If you’re running a shotgun, pistol, or any firearm with a “drop comb” where the cheek rest is lower than the top of the receiver, the Low Mount will serve you just fine. If you go with the. 83 Mount, you’ll also get the Low Mount – if you plan to move the optic around multiple platforms, go with that option!
