Thread: IR Torch recommendation

The unit is very sensitive and it's possible that a minute amount of back scatter from the stainless barrel may be occurring when the torch is in floodlight mode. Also if the scope has a big arse objective bell there could be reflection from that.
Run the unit off the scope and if there's no glare it's a mounting issue.

Thanks for that. Pretty interesting info. I dont want to keep blowing dough in a search for a solution but I am seriously considering a change to a scope with external parallax/focus adjustment at this point
