Following on from a recent post praising Armex for excellent customer service I have just received a reply from Daystate regarding a request for O ring sizes for two LR90 rifles I own. 'Unfortunately we are unable to provide sizes of all O rings, but do provide complete kits, size and shore matched upon serial numbers'

Considering other manufacturers list O ring sizes in owners manuals (Air Arms for instance) I think that is a poor response from Daystate
