Sight Adjustment BSA Scorpion


I’m hoping the collective mind and knowledge in ACC can help please?

I’m trying to find the details BSA Scorpion Rear sight adjustments for a range of 5.5m.

So in essence, what in millimetres is each ‘click’ worth at 5.5m? This is in an effort to correctly and efficiently zero an Air Rifle to a user.

Many thanks in advance.


You’ll struggle to get this, nothing was published by the manufacturer and there is nothing in the PAM.

Recent guidance offered has been 4-5 clicks per scoring ring at 5.5m.

There are 2 factors with the vagueness the inaccuracy of the sights adjustment and the very short distance from muzzle to target.

Yep, nothing written down that I’m aware of.

Depending on the cadet & the specific rifle sight, 3 - 5 clicks equates very approximately to the width of the scoring rings.

We have one rifle that had full right sight adjustment applied - no opportunity to move any more to the right if a firer held a group left of the bull. Not used since back from recent servicing at BSA, hopefully the sight was tweaked.

Big surprise when we zeroed them for 10m (Regional competition), I had to wind DOWN several handfuls!
