Varazar, I'm happy you brought up this question as I too am considering a non-restricted 22 rifle that also must meet a minimum "coolness" factor.

From what I could find that is in .22lr and are "tactical":
- Mossberg Tactical (M4/AR Style)
- ISSC MK22 (based on the FN SCAR design I think)
- Umarex 416 (M4/AR style based on the H&K 416 rifles [hk22rimfire.com], not sure if it's available in Canada or if it's non-restricted)
- Ruger SR-22
- Remington 597 VTR
- Kel-Tec SU-22 (recently read about that one)
Those above models are ready to go and not always the best looking options (last 3 in the list I think are the worst looking [don't flame me, it's just my opinion]), but you can also get a Ruger 10/22 and put an aftermarket stock as others have indicated like the Archangel Nomad/Marauder or Troy Industries stocks. You can even put it into a Muzzlelite Bullpup stock which I just recently found.
I'm actually leaning to either the least expensive route, Mossberg 715T Flat Top (approx $350 before taxes and accessories), or the Ruger 10/22 with an Archangel Nomad/Marauder stock (approx $500 before taxes and accessories).
Oh, and the images provided by Pavment & Timber look friggin awesome and really make it difficult to choose!
Timber, what changes did you do to the Mossberg 715T as it looks better than the stock model?
