Made in 2009 and has about 1000 rounds through it. Complete DD upper.16" CHF 1-7 DD barrel. DD Upper Receiver. DD Bolt carrier Group, DD OMEGA X 12.0 FSP free float rail, Pre-RIS, PWS brake, BCM stubby vertical grip, Colt charginghandle. Great for that Block IIish clone. This upper shoot lights out. $700 for the upper which is more than fair. It was $1,200 new in 2009. It would probably be $1,600 if it was still available today. ACOG is not included or available. I have the original box for the upper. It's not in perfect condition it has been used, but is still an excellent low mileage upper. I live in Leander and will only meet in Leander.
