It seems that with whats available already in Canada, the already mentioned PGW, and the rifles available from ATRS and others, the tactical bolt action market seems pretty well covered.
I do like the above the barrel bipod, a buttstock mono-pod and after using my 30" barrel + 2.5" breaked rifle a bullpup would be nice to be a little handier when the going gets thick. I would like the weight about a pound under what Jerry mentioned, around 9 pounds for the bare rifle, that would be nice. I would also like the scope rail to be integral to the action, and canted 15moa.
How about the entire lower ring being part of the reciver and machined to accept the burris inserts? Haven't seen that yet, and it seems like a good idea.
I think the reliability has to go without mention with a tactical rig.
