Could any of them have been stateside? Woodland camo guns? The only reason I ask is that I remember reading and hearing that from an authority, or someone who I consider to be.
$12k is certainly an anomaly. And well could’ve been part of a possing match between two motivated or uninformed buyers. The market is pretty soft right now and I’d agree that $5-6k is about right for the moment.
Welcome from up in Virginia. The camo HKs are certainly valuable rifles but difficult to peg as they don’t seem to change hands often and many just sit when they come up for sale due to unrealistic prices.
