I have for sale, an Aimpoint M4S, bought directly from SWFA, asking $550.00 shipped.
Sight has not been fired with, and comes with Aimpoint limiting knob type mount. Has a Killflash installed, as well as flip-up covers. Condition : Like Brand New, never zeroed in or adjusted.
Box and all paperwork included. Will accept USPS Money Order, or check, but check must clear my bank before shipping. Paypal plus 3.5 % is O.K. (Discreet)
Please post an "I'll take it" to the thread, followed up by an IM.
