I use it with my MKH-416 and Sanken CSR-2 sometimes, but it fits almost all shotguns (I didn't ever seen any shotgun which can't be used with this mount).
Any word said about this mount is less, then it actually does. This is the most versatile, durable, lightweight, silent and convenient pistol mount I ever hold in my hands last 12 years I do my job. I know only one exception of use this mount - it is strong wind, more than 5 m/s, when Softie windshield cant help you.
Only Rycote products can do the Thing that will make you forget about unexpected noises and concentrate on sound you record.
You can use it with stock light windscreen or with Classic Softie, with or without boompole, with or without plug-on and so on... You can unscrew the handle and mount the mic holder wherever you want.
