Tracffy Laser Bore Sighter, Red Dot Laser Scope Sight Tactical Collimator Kit for 22 to 50 Caliber Rifles

I had seen a lot of negative reviews about this product but decided to take a chance, mainly because I was curious and love a mechanical challenge. I found the product to be quite accurate and needing no adjustment despite what other reviews had said. I tested the laser in my .22 air rifle and to 30mts it was almost in line with my scope which I had set up using the old shoot and adjust method. In the kit is an Allen key that can be used to adjust the laser, which I know defeats the objective of buying the product in the first place but it is there and once set up you will never have to zero in again in the future. Many thanks to the seller for their customer service.

I bought this to set up my Hawke telescopic sight, as I am sure it was 'off target', and I have no where I can safely set the scope up with paper targets/on a range. I followed the instructions exactly (even removing my silencer, which they don't mention). I then found that there were no batteries supplied (it was in the advert, but hey it was £13-00). I set my scope up, and then thought, I wonder what happens if you rotate the collimator - sure enough, now off target. This is a pile of crap, and my advice is to spend 50p on some paper targets, find a safe location and set it up properly.

The laser is held in the barrel by a tail with a collar that brings it to a snug fit; but one plastic collar is insufficient, two would be needed to centre the device in the barrel. I know the taper on the laser is supposed to provide that second centring , but the weight of the laser will pull the taper down and away from the muzzle. And remember, light travels in straight lines, your pellet follows a parabolic curve! So this only works for ONE range setting.

Comes un-centred, when in the barrel the unit made a 250mm circle at 15m distance when revolved. after 20 - 30 mins of fiddling I put it back in its box and sighted through the bore which was near enough at the 50m range to be within 50mm of centre. 1 - For Sale here if you're looking.

Easy and accurate to use
