SOLD! I'm selling my barely used extended quad rail hand guard (Carbine Length) I've use this for less than a month and got a different hand guard. So I have no use for this anymore. it is in excellent condition. no wear and scratches. I paid $50 for this. I'll let it go for $30 cash. Rail rubber guards included. PM me if you're interested. FTF Hillsboro/Beaverton surrounding area. Thanks for looking.
