Picked up this rifle about two years ago on a whim. I was familiar with the KAC name and their quality, and have had a few of their more recent production guns, but this one has me a bit puzzled. I cant seem to find anything online about it. It appears to be a pre- "mod1/2" series SR-15 with their in house version of FDE ( I think they called it 'taupe'). also has their rail-integrated front sight and supposedly came factory with their 600m rear sight according to the original owner. I included the link below that was the only useful breadcrumb I found referencing its original manufacturing run. Any additional info such as manufacture date estimation, an original price or SKU/MPN would be appreciated!
