The MI-24C 91/30 rail system for the Finnish M39 rifle is the latest addition to the RSI product catalog. This rail is modeled after the US Armies M24E1 sniper rifles picatinny rail system. It mounts using the same hole pattern as our standard mounts with an additional stabilization mount at the M39’s rear site. Designed to allow for expansion the MI-24C rail includes 2 additional attachment points on either side for accessory rails (available separately in November) to expand it’s capabilities even further. The MI-24C rail system can be used with flip up sites, conventional scopes, LER scopes or used in combination with night vision and other rail mounted accessories. If your looking to build a tactical M39 give this mount a try.
