Hey Guys, A few years ago I happened across an awesome Website that was extremely detailed & informative concerning almost every U.S. Government issued / utilized Carbine type CAR-15 / M-16 Carbine variants. This Site listed each & every variant, detailing each individual change, & or upgrade, etc. I had it as a 'Favorite' on my Device, but last year when I upgraded to the most recent edition, the darn thing deleted all my saved sites !! If anyone happens to recall, & or have knowledge of this particular Site I would really appreciate hearing from them. THANKS

Best, Dom P.
