Has anybody used or heard of anybody using the Pulsar DFA75 Digital Front Attachment? I have the Pulsar N550 and it works great but im thinking about selling it and going with the DFA75.

I had two. I sold the spare I had and bought an X sight.
I've had the first one I bought for around 2 years and it's worked good so far.
It's mounted on a .223 bolt rifle.
Sometimes I would stay in my deer stand till dark, put it on and hunt coyotes for a couple more hours.
No need to carry a NV rig.
It's a nice unit, but you really need to get the adapter ring fastened down, or it won't hold zero.
I know there's a company that'll rent NV scopes, so maybe you can check it out before laying out the dough.

I like mine, and I hunt with several rifles. I would like to go to a thermal but can't talk myself into spending the $.
So far it has been on my 6.5 Grendel, 6.5X284, 300 Blackout,and my suppressed 308. It works great.

I like the option of moving it to different rifles, but if I'm going to spend that much I think I might bite the bullet and go thermal.
