This is called a peep sight or aperture sight, right?

My buddy and I were sighting in the VEPR and were noticing that the major limiting factor was the rear sight.  It's hard to focus on the front sight tip on the VEPR with the way the rear sight blade obscures and blurs up my vision.  I am uncertain as to which brand to get.  Red Star Arms has 2 brands on their site, Mojo and the Microclick sight.  I heard Krebs had a nice one too.  Any recommendations?

This one is out of stock but it has my interest and it's a Krebs: www.bhigear.com/index.asp?PageAction=VIEWPROD&ProdID=969

Maybe Krebs will make some more of these ...

I use the Kreb's and it is great. Much better than the original blade. www.krebscustom.com/CustomParts.html#akpeepsight

I opted for the Mojo microclick, apparently there weren't very many made yet for the AK's.  I will put up a range report with pics as soon as I can.
