Re: rear iris centering mirror

Thanks TH. Reason for confusion is here is 10.9 (store) description of what it does and how to use it: " The Mirror is a tool to teach and confirm proper head position and sight alignment. It fits on your rear aperture and reflects the image of your eye back to you...IF and only if your eye is ...

Re: rear iris centering mirror

I'm still not sure how would you use this thing. Do you want to see your eye reflected back or is it supposed to disappear? Are you supposed to line up the hole with your reflected pupil.....???

Re: rear iris centering mirror

Great, thanks for your response. Also the instructions from 10.9 is that if you see your eye reflected back at you, you are not in line. They say the objective is to not see your eye, ie. no reflection = in line?????

rear iris centering mirror

Does anybody have experience with using this device? Small mirrored disc with center cutout. I understand you would mount it on the rear of an iris, look through it centering the hole, your foresight and the reflection of your pupil and determine things like how high your cheek piece should really b...

Re: issues converting from 18 to 22mm sight tunnels

Maybe it's just me but I have always increased or reduced white space round the tunnel by moving the rear sight closer or further from the eye (eye relief). Altering the distance between sights is much less effective. I do agree altering the diopter size doesn't do it either. I agree, you can get m...

Re: issues converting from 18 to 22mm sight tunnels

That's interesting, I'd not considered that a larger tunnel could highlight movement in your hold. A larger foresight aperture can, if you were using one that didn't allow enough wobble room, and overlapped the target. But I hadn't thought that just a larger tunnel could. Bear in mind if adding an ...

Re: issues converting from 18 to 22mm sight tunnels

Out of interest why did you change? Most folks I know who use a 22mm foresight do because 1) That's what came on the rifle (e.g. Feinwerkbaus), 2) they have an extension tube already and want the larger tunnel to balance the sight picture. I know a few who chose to replace an 18mm tunnel with a 22m...

issues converting from 18 to 22mm sight tunnels

Finally figured out a 4mm riser on the rear sight gets me back to usable elevation range. Now my issue is very little air between rear sight tube and front sight tube. Hard to center. So it's moving my head further into the rear iris to see more air around the tube. I did order a 10" bloop tube...
