What:
Excellent-condition KAC 200-600m rear BUIS. This is the non-micro version. I am the original owner and it has seen very limited use. There is no marring on the screw and it looks perfect.
Info from KAC: http://www.knightarmco.com/shop/index.php?main_page=product_info&cPath=3&products_id=40
Price:
$157 shipped
Terms:
Payment by Paypal (“gift” or +3.5%) or USPS MO.
I will ship USPS Priority with delivery confirmation (so, the price is $150 + $7 shipping).
Trades:
KAC black folding front sight (P/N 99051)
Thanks for looking!
