I just put this together but I'm lacking a few small parts as the ship they're being ridiculously long. It has a Wilson Combat matched set of receivers and a Daniel Defense 16 inch 6.8 SPC 2 Barrel. And I won't bore you with the rest of the details but it's all mil-spec parts that I like and having my other 6/8 builds. I'm just waiting on the gas block and a couple of other small parts to get it shooting but I'm anxious to see the performance of the Daniel Defense Barrel. I have two other 6.8 and they have Wilson Combat barrels on those and they're extremely accurate but they're stainless steel barrels. I wanted more of a tough Workhorse Barrel on this one so I don't know what the accuracy will be but we will see. I'll post targets as soon as I get her up and going.
