V1 came with #30 size, as the hopper was used more the belt/0 ring stretched which would stop the loader feeding consistantly, V2's now come fitted with #29 0 rings which eliminate the previous problems.
Ok, I bought it and it's a V1. I've checked the Kee catalogue and can't find the aluminium feed neck and o-ring as a spare/upgrade. Does anyone know where to get them.
