I am trying to get a peep sight set up on my aea airgun. Looks like you have a 3-D print clamped onto the end there, that is a good way to do it. I had printed one that slipped over the end but just friction fit. Works ok but can slip if bumped obviously. I am going to follow your example, thank you
I got a set of these to put on my Armada.Set at 20 inches apart.Now if the snow would melt.Ultradyne C2 Sight Set Flip-Up Aperture Front, Flip-Up Rear: https://www.midwayusa.com/product/1022421473?pid=508683
Unfortunately I don't think we are going to be able to help you with this. These were designed for m193 ball ammunition, so the math is all based off that if that helps. Thanks,
