Anybody know where I can buy one of these?

For a no-drill mount there are American B-Square and S&K mounts. The S&K are extremely solid but run close to a hundred bucks up here.

There's a fellow on canadiangunnutz called "Gairlochian" who turns out a no-drill mount for a Number 4 that he sells for a third of that. There is a thread on cgn in their Milsurp forum with photos and a test report.
I'm using an S&K because that's what was on the Number 4 when I got the critter and I haven't fnished playing with it yet.

Check them all out before spending any money. That Fulton mount sounds worth checking into, especially if you can get it for under the national debt. They do make good stuff; I just normally can't afford it!
