This is correct. Be gentle with the front sight. This small of a hex head will either round out the hex driver (if you're lucky) or the screw head (if you're not) easily. Be sure to apply steady pressure into the screw head while turning.I have done several, installing Firesights on the dovetail models of the MilPro.
The REAR sight takes a 2mm hex/Allen wrench.
The FRONT sight takes a 1.5mm hex wrench.
SOME of the sights that I have removed had the set screws very tight with a LocTite type sealant.
Use a GOOD quality 1.5mm wrench because some of the cheap hex wrenches rounded off rather than removing the set screw.
If you install FIRESIGHTS, they take a .05 inch allen wrench. I bought them in quantity on eBay.
