AFAIK the original company was sold and Tim La France went to Surefire. Not sure the LFS of today is related to the company from the 80's. So worth a shot. There's also a Tim La France gunsmith in CA, might have to call to find out if it's the same.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
