Would like to get the sight off so I can mount my new hand rail, but would like to save the sight if possible. Can I cut (and probably trash) the sight off, without hurting the barrel? And perhaps use a removable sight in its place.
I am assuming that you are referring to a standard A2 style sight base...do not damage it in any way, it is also the gas block for your rifle and damage will negatively effect the rifle's operation.
To remove locate the "big" side of the pins, generally the left side when viewing from the rear. The pins are tapered and will only go out right to left. Using a pin punch, dead blow mallet and a vice you should be able to drift the pins out. Bear in mind, however, that some rifles require extreme force to get the damned things out. WD-40 or some other penetrating oil may be helpful, if all else fails have a gunsmith press them out for you. Better to spend a few extra dollars than bend or damage the barrel or receiver. If you have to dremel them out be prepared to reinstall a replacement gas block, low profile for under the foregrip or railed to accept a BUIS. The sight is an option, the gas block is not.
