I've got the Mag 50 on my Ultratec. Works good. First time using a scope and really don't notice a difference. Probably just me. The lense can be removed easy enough to shoot with out. I do have a minor problem that I have to contact Tox on, the lockdowns do come loose. I've shot Tox sights for 4 years now and still like them. I'm using a Hybrid V for hunting still.
