Question: Fiber Optic Front Sight for KJW KP-05
 

I'm in love with my new KP-05 that I got this past weekend. The only thing I'd like to change at the moment is the front sight, replacing it with a fiber optic one. A while ago, I got this set for another gun:

Looks like both front and adjustable rear have a different dovetail cut: KP-05 has a wider one than the set I have.

Could someone please suggest a fiber optic front sight that would fit a KP-05, ideally the same height as the standard KP-05 front sight? I'm quite happy with a non-adjustable rear, but it will need to be replaced if the front sight's height is changed.
