I want disassemble my 2240 to do some custom mods starting with the front sight. For the life of me I can't get it off even after some vigorous tapping (with a hammer assist). Isn't it supposed to just slide off fairly easily?
I finally put the sight in a vice(!), twisted it around, and it finally came off.
One light tap on a wooden block placed behind the back edge of the sight should take it right off. :)
Yes, it is pressed on. Try holding it in a vise (protecting the finish) and using a block of wood against the sight and tap the wood. Should pop off. I've only had one tight enough to require this.
