That is really cool... I would think with that peep sight further down the barrel us bifocal guys could focus the rear and front sight real easy. Also because of the different aperture opening size, it would be more of a ghost ring effect and a target peep. Very nice job. I will be interested to see how you do on the range with it.

Maybe I should send you my sight off the Lyman Trade Rifle and you could make me one like that..
