Anecdotally as the the thread wears on people are finding that 80mm or more works better than the official 75mm and requires an 18mm to 25 mm spacer There is a mail order shop over there linked in the thread that sells a massive range of T2 spacing rings that will suit if you can't find one over here I am after a 25mm T48 spacer for optimally using the unit visually and using a little infocus .
Theyve been in production for years now - you would think they would have given the mechanical barrel length a bit of a tune up by now. Such a spacing error in the optics of an RC would be `fatal' .
