Arrow Laser Shot (Mk1)


Recommended Posts

Hello,

 

Quick query I need help with please. 
 

I have picked up an arrow laser shot mk1 off eBay, I got it for a good price and it’s come with what looks like both 12 and 20 bore adapters. 
 

Only issue is the 12 bore one doesn’t appear to have those ball bearings in the tube, which I assume keep the tube central in the barrel? 
 

Just tried it now and when I rotate the laser I get different POI’s from the laser, obviously because it’s not maintaining true centre. 
 

I assume the missing ball bearings are the issue? 
 

thanks

 

Lloyd

On further tests, the laser also doesn’t work with the 20 bore attachment on. 
 

No idea why, everything exactly the same and works with the 12 bore attachment.

it looks like you have to swap the centre tube over too the 12 bore with the ball bearings 

 


Bit odd that they wouldn’t put 3 ball bearings in each one? 
 

Nuts that you’d have to swap it over. Surely that’s not right 🤔🤷‍♂️
 

 

Anyone else any idea? 

On the plus side, the 20 bore version worked, Just seems a bit temperamental

The version I have is a bit different, but the same ideas apply.  There is one laser 'head' and a single aluminium 'tail' on which you attach one of three silicone rubber guides, which I presume cover 12, 16, 20 and 28 bore according to the rather poor label in the lid.  See photo.

It looks like the balls and centre 'plug' will fit either the 12 of 20 aluminium piece on your version.

well the 12 bore has no centre piece  so swap it or return it as missing bits

 

That's the thing, I was wondering if expected to swap them over, but I don't think so, as the centre piece and those balls are firmly wedged in there. 

I think they are missing from the 12, as expecting to change them everytime would be ridiculous. 

 

I will send it back in that case.

Yes the back parts make it centred in the barrel so you get an accurate idea.

 

I have ordered one the same as yours, a MK2, and will send this one back I think.
