You like range work and a fair bit of accuracy.
All your firearms can be potential SHTF tools should rule of law become a problem.
This opens up the restricted category for you.
This is important as restricted firearms tend to be range only.
More importantly, restricted firearms actually tend to be cheaper in price than non restricted!
Next decision is caliber.
7.62 NATO or .308 is pretty darned expensive. Quality ammo is even more expensive.
I'ld recommend 5.56 or .223 as it were.
Way cheaper than .308 and by the nature of the round and ballistics fairly accurate.
Now for the most basic choices.
.308, get a Norinco M305 which is an M14 copy that is non restricted.
You can modify it to taste, but it can get expensive depending on your taste as it were.
Price, let's say five or six hundred but then you will pay far more for ammo in the end.
The ammo you have been warned about.
For 5.56 restricted, the best bang for buck is the Norinco M4 or M16 clones.
$600 brand new, get permisison of the moderators to join the EE (eqipment exchange) and shop for deals on the site here.
Parts to modify are plentiful and cheap, ammo costs less.
I have to admit I am rather fond of the longer barrel DA556 from Canada Ammo myself.
Most guys like the 14.5 inch CQ forom either Canada Ammo or Marstar or so many other dealers.
Only hiccup is the restricted status makes it range only.
If you ugo this option, then you can spend the five hundred bucks you saved on a crate of a thousand rounds of ammo, or maybe buy a pistol instead.
I you want 5.56 and non restricted, then I recommend the T97.
You pay for the non restricted status in Canada.
If you like shooting iron sights, then it will be $1,000.
If you want something to put an optical scope on, then it will be $1,250 or so.
The benefit of this being,as non restricted, should you want to take it out to a farm or bush, it is ok being non restricted.
There are a lot of great rifles out there, but like the SG542 or the SG540, prices can put you off from the start.
Best advice, get something that is not crazy expensive, join a club, meet folks and learn from them and their firearms too before figuring out what you really want to invest a lot of money into buying.
This sight can be an awesomehelp so long as you realize a lot of folks have a lot of strong opinions about various brands.
Don't worry about the quality of Norinco, they go bang and they're cheap.
