Yes. There are three retro 7s that I know about here in Ottawa.
I would happily let you take mine for a short spin at the field. Where abouts do you play?
Or I could meet you some time next week at one of the paintball stores if you want to try one sooner than later.
I might possibly make it out to one of the local winter games but 12g and Ottawa winters don't mix so well. I can still bring it but you wouldn't get the max performance from it like you would in warmer weather.
PM me if you like
