I'll need my tin hat on this one but here goes!!
Ive been asked to bang this on here, but at the same time embarrassed to do so, more so for the person who EV2 it was before i bought it.
I bought the Air Arms EV2 MK3 last year sometime from a well known gun shop supplier, and i was GOB SMACKED when i noticed that the gun barrel was shimmed with rubber inner tube where the barrel band was.
Now ive seen everything i thought, and asked the question WHY ????, and was told that the previous owner had shimmed the barrel up instead of shimming his scope, here are some pictures -
The gun is now back to its original state, and shoots a dream now the barrel is screwed down to the barrel band.
