With what you are saying,How ever I think it is worth pursuing.25 cal is an easy upgrade for this class of rifle. Do I think you will be the only one to venture into this area? NO!! But I do think that proven performance from an experienced maker carries a lot of weight in the airgunning community.Yes, The fact of this conversation will be proven when you sell out of the single shot trays, Don't think so? post that you have them to the marauder forum. They would welcome the fact that your willing to venture out into an area thats already looking for improvements (bling!!)I'm a staunch supporter of a guy thats willing to take a leap to strut his stuff! Would I buy just one? NO!! I want six for my self (Got a lot of family that wants one too)So I'm saying it public.I'll help any way I can, I'll tear down one of mine for any measurements needed. Enough said, Regards,
P.S. would be the S&^TS to have a five hundred dollar gun with a two hundred dollar upgrade out shoot a rapid!!!at twice the price!!
