The Tavors have arrived today. And I can see what you mean Richard about increasing their thickness.
Size wish they're fine. They'd even perhaps me a smidge smaller if you're looking to be 100% realistic. As they are they aught to work with some figures that I can sculpt. Probably too small to just lop off one of Wargames Factory's SA80's butts and fix on just the front of the gun (you'd need to increase the proportions by a good bit to manage that).
I'll see when I can fit a test sculpt into my schedule (between painting toilets and plastering walls ...in miniature of course), then have a post in my own modern thread once its done.
Thanks again Richard, you've been just great doing all this.
