Personally I find the AR platform aesthetically unappealing and much prefer the nostalgic look and action of the Mini-14 - especially when wearing wood. Concerns about ultimate accuracy are valid - if you are looking for a 200+ yard target rifle then you may be disappointed. That said I would bet the Mini to be every bit as accurate as Matt's M&P.
Magazines for Mini in 5/10/30 are available but as stated are more $ than AR versions. For consolation the Ruger magazines are excellent quality. The same platform is also available in 7.62 with the Mini30.
