removing rear sight on tm hk g36c
 

how do you remove the rear sight on the hk g36c also once it is removed can it be attached again?

Just tap out the roll pins in there. The front and rear site are held on by 2 pins, just get a small punch and hammer them out.

will they fit back in after?

No reason they shouldn't, I never tried come to think of it, and too lasy at this moment to find out. They are just roll pins, once you tap them back in there its a straight friction fit so there shouldn't be a problem.

They'll fit back in no problem.
