When working on the sight attachment pins. Note that when you are trying to drive the pins out that some of these pins are tapered , that is they go out from one side and drive in in reverse. If you try to drive the pins from the wrong side they get tighter as you drive them. As with anything mechanical, don't force it. Use a small hammer (ball peen) and pin punches of the appropriate size, otherwise you are likely to mar the surrounding surfaces. firm taps should do the job. Take an old block of wood and drill a hole (1/2" or so)all the way through. then use the wood as a support piece under the barrel and drive the pins into the hole in the wood. They actually make an armorers block specifically to do this job, but for a one time job, a block of wood works fine.
Air soft guns are not made to mil spec ( or any spec for that matter) but be aware of this issue if something does not seem right when you attempt this procedure. Remember DON'T FORCE ANYTHING
Even a fool is thought wise if he keeps silent,
and discerning if he holds his tongue.
