I just picked up my third Big Rock Sports KMK512GC Model 0188. My notes I have from Chet says there were 894 made for Big Rock Sports from 2002-2003. But in Rene under Scarce Government Target Models in the price guide it only has KMK512GC (maybe 300 produced). No model designation or distributor. My question is what KMK512GC is that in Rene. I am assuming it is the Big Rock Sports one. The only other KMK512GC I know of is the Talo USST MKIIs. But as hard as it is to find the Big Rock Sports model I would think the 300 maybe a more accurate number. Just for comparison The Great Eight had 902 made and as hard as they are to find I see several more of them for sale than the BR KMK512GC.
