Sorry for the stupid question but I've always been told not to dry fire, so doing this will be ok?
Apparently all you need to do is cut a piece of opaque plastic same diameter as your objective then cut a centers hole 1/3 D of your objective lense, and place that piece in a scope cap. Acts like an aperture.
Gonna drill out a spare lense cap and try this
Get an IOTA. Bob Raymond sells them.
Has anyone tried this? I think I will give it a go and let you guys know how it turns out.
Anyone know of the cheapest place to get BC caps for 56mm objective?Can confirm this works. Did it today, and was able to focus my ERS 3.5-21 at about 12 feet. The target needs to be very well lit for the reticle to show up, because you're reducing the amount of incoming light substantially.
