A bit OT but still Commonwealth, C3 sling

[jmoore]

As a little aside, are the sniper mounts and telescopes readily(?) available?

Not really. A friend built a mount from scratch. I've got a real one somewhere, along with a scope. The Unertl/USOptics MST100, etc. is similar but the elevations are different on the Canadian scope. US using 168/173 gr loads and the Canadians the 147gr.
