Re: Barska Swat series scopes
A paper towel roll, painted black, with pube reticle, rubber-banded to your rifle would be a better use of resources than a Barska SWAT.
If on a tight budget, SWFA SS10X, $300 (if they ship to Canada), it'll shoot much better than you and will get you to 900 yards. Mechanicals are very reliable, glass is adequate.
Or, for $100, I'll sell you the paper towel scope.
