I was just in Hi Calibre yesterday, and got to see the new SKS peep sight prototype - Think "Mojo" but infinitely more practical for competitive shooting/ quick acquisition.
It is more "overwrought" than the tiny peep tube, more akin to a tank - certainly more durable and practical for SKS applications!
Looking forward to seeing - and possibly first 'dibbs' - Hi Cal!
Cheers!
