The Aimpoint is LNIB, mount is used, includes Eotech spacer. I want $475.00 plus shipping. The BUIS is LNIB. Will take $85.00 shipped.---SPF--- Will consider partial trade for a free float rail that will fit on a gas piston AR carbine. For example a POF Predator P-4 carbine length rail system. This one retails for $229.00 Please don't expect more for your than that even if it is NIB. Thanks for looking. If you need pics send me your email. I appreciate your time. James.
