It isn't adult sized, but I think its the best "pack 22" currently offered.....

1) Stainless steel barrel
2) Comes with sling swivels
3) Magazine feed
4) Semi-auto
5) 16" micro-groove barrel (accurate)
6) Decent sights
7) Easy to mount a scope on
8) Light weight
9) Quick / Easy take-down with no parts to loose

I don't own one right now, but its on my "must buy" list. They use to make a blued version that can be found on the secondary market for a lot less money. However, a new stainless model is only about $200 so I'd rather spend the extra and get the corrosion resistance.

Eventually I'll buy one and make the following modifications:

A) Add a sling with quick-detach swivels.
B) Add a Leupold VX2 2-7x33mm scope (only adds 8.5 ounces)
C) Wrap the barrel with 550 paracord.
