Larue milspec receiver extension at $45 Shipped. Like new. PERFECT CONDITION! No damage. Used this on a build and went with a A5 setup instead. Perfect shape and had roughly 200 rounds on it. Will throw in the plate also. No nut included. http://www.laruetactical.com/larue-receiver-extension
Paypal preferred but will accept USPS MO. Insurance on buyers dime if desired.
Thanks
