Magneto v3 with wiser mount. The bayonet is almost brand new. The original one quit on me and had to order another one. The wiser mount is broke but I'd imagine you can order the part. The 3d printed part that holds the bayonet broke so I super glued it. While doing that, the super glue got into the slider and now it wolnt move up or down. Decided to upgrade to a bullet seeker. $350 obo
