The video below better explains the process for removing the factory SCAR front sight. The short version? Drive out the roll-pin on the right side nut. Unscrew the T25 screw holding that nut. Take a hammer and punch and drive out the sight from the gas-block dovetail. Left to right.
Special note: There are some parts that fall out when you do this, so be prepared to account for them. At the moment, I believe there is a ball bearing of some kind in the system that is easily lost after driving the sight out of the dovetail.
How do I know? Well…I don’t exactly. Something rolled off the bench and hit the concrete floor in the armory. By the sound it made, it didn’t bounce like a spring but more like a spherical object.
We don’t intent to reinstall, so I wasn’t about to spent 3 hours looking for the darn part.
