Sytong ht66

Well i went down the rabbit hole and into infrared for shooting bunnies,
Brought the ht66 clip on, will be fitting it to a 22 either a t bolt or a 10/22
Had a quick look through - just the bare unit , yep works in the dark! , bunnies at 80m are pitch black rabbit shapes in ghost grey paddock, that’s with no scope attached, have not gone into setting up , just straight out the box !
So once I fitted it to a scope,/rifle (am going on the lathe with plastic pipe or nylon maybe ,down to a better fit than the supplied tape)
Anyone got some easy advise /info on setting the unit up or is it as easy as clip on n away you go
Cheers

Thanks for that, I had a look in the gun cupboard , found a old niko gold crown with a bonus of it being ao that fits perfect, so will swap scope ova sight in, ordered a rubber slip on butt pad,
