Help me diagnose mirage or environmental disturbance.

[ALCOAR]

I've seen mirage bands on certain precision bolt guns, namely the Sig.

If on max power, try backing it off some

if you must and I've never done this--

Idea's to mitigate the effects
use "tactical" rubber bands to attach the "blind" to the scope sunshade, long enough to divert the heat wave.
sunshade
longer rail and solid covers on top
longer rail and if not using a front sight-slide the solid cover forward of the rail like a diving board to act as a mirage band

Thanks Mark for weighing in and as usual its with excellent information. I have backed off a bit @ 10x a time or two when experiencing mirage effects and it has helped a bit.

I must admit I hate seeing rail covers on the top rails and so I honestly never even thought about taking some xtm's(wont require removal of front buis) and using 4 of them on the top rail to negate this should it happen in the future. Solid tip there brother

No worries, hope it helps out!
