Being rather poor and starting out, I purchased a lot of target front sight gear mainly to get the 22 mm front elevation adjustable MO’s front. What came with is a mix and match of clear 22 mm front apertures which will not go in the base tube, a couple of eagle eyes with threaded piece and the base it self.What do I need to get this on the go? I would be happy with some steel aperture inserts to use with one of the eagle eyes. I am in Canada See pics for what I have .
