The weather was nice here in the St. Louis metro area yesterday, so I made it to the range.
Luckily I brought two AR's with me....one in 7.62X39 (it's a DPMS and wears a Vortex 1-4 power scope. I want to say it is a PST Viper, but I'd have to look at the box again.) The other is my Franken AR in .223.
I say luckily because I loaded up both guns into my car....got halfway to the range when it donned on me that I forgot to bring ammo for the .223 .
So here are some pics:
The Vortex has an illuminated reticle which looks like this:
So, like
dryflash said above, the blue post it notes provided the best contrast for me.
That is just one inch spacing between the blue squares. (And the orange squares).
Pictured in OP is the bright yellow squares. That was actually the worst to look at, so I didn't even bother shooting it.
The adjacent squares with no gap wasn't that great to shoot at.
Thanks for all the advice.
