### ⭐ Scope torch mount
*by S***H on 24 June 2025*

Very poor, there is too much wobble when the adjustment is made, I set the IR beam to the middle of the scope display but the poor fitting movement in the design means you can move/wobble the torch leg and right so much that at 50 yards the edge of the IR beam is only just on the centre of the scope display. Anything to be shot further than 50 yards and it’s very frustrating. I couldn’t wait to get a replacement for this, I should have spent more money in the first place. Don’t buy, they are crap.
