Three months ago I took delivery of a dozen brand new Mark I FVT rifles for my local gun club. We use the rifles once a month at my local gun club to teach between 1 and 2 dozen kids the fundamentals of rifle shooting using the NRA Marksmanship 4 Position Rifle Qualification Program. Each rifle is fired at least 100 times each month --- not sure if that qualifies as 'hard use" or not. Is anyone willing to share a maintenance regimen as well as the products you utilize? I'd like to minimize the potential for surface rust from all the handling by getting ahead of it if at possible. These rifles are a long-term investment for the club so keeping them maintained is a priority. I've never had to maintain this many rimfire rifles before, so any suggestions and recommendations are greatly appreciated.

Thanks.
