I've got a 550 on my .22. The 750 is an updated version with a better picture and longer range. Does it work? Yes. At a cost. I'm not convinced about the quality of Pulsar NV. Faults and warranty claims are common and though I haven't used mine on a CF, I had problems with mine holding zero on a rimfire and had it changed (without quibble) under warranty and that does not fill me with confidence. There are other issues. Its a heavy unit with poor ergonomics and it will need a powerful IR illluminator for CF use. I use an NM800 which is excellent but adds up to quite a lump. The adjustment increments are 20mm at 100 m (on the 550) which is very coarse, especially on a CF. And It restricts the rifle to night use. In theory you can use digi sights in daylight. In reality don't bother. The resolution just isn't good enough.
If it was me, I wouldn't use a 550 or a 750 on a CF. I'd get an Archer add-on, ideally an objective add-on. These need a quality scope to get the best from them and preferably parallax adjustment. I wouldn't want to tie up such a useful rifle as a .222 to night use only. Better to get an add-on, or if your pockets are deep enough a true day/night scope like a Longbow.
