I remember when the first Bren Ten came out - was shooting IPSC at the time in California with SWPL. Someone came out with one, I think it was Jim Zubiena of Miami Vice fame, and shot a match with one.

Wanted one at the time. But I can't figure out the attraction for a Vtor copy now. One can get essentially the same idea with EAA Witness - much cheaper and while Witness' have their issues they mostly work.
