I was pretty sure the Mustang would be my one an only in-line. But I have to admit I have ahankering for an X7. It's a sweet little rifle - got a crushon itas soon as I picked one up.

The aperture on the X7 peep is pretty large, even bigger than the "hunting" aperture for the Lyman 57 peep sight. I don't think it would be a problem in any conditions in which you can see the deer with your naked eye. On the other hand, a 4x compact scope would be REAL NICE.
