    I just got this receiver and haven’t assembled so I can’t review how it shoots yet. The barrel and Hera hand guard look really nice, but there are multiple blemishes on the finish of the receiver itself. I plan on having it DuraCoated so its no big deal.

    I have not shot thia yet but will follow up with another review after i do.

    Pros: fast shipping and was packaged very well. Everything feels solid and fit well on the lower and the price is great. Customer service in helping my selection was very friendly and good. Overall finish is excellent havent found any issues on it yet but its unfired.

    Cons: only trace of oil i found was on the dust cover otherwise rifle looked and felt bone dry. It came with a compensator attached that i had ordered separate and the actual flash hider is mia. The rail is a couple mills lower than the upper.

    Just completed my build with this addition. For this build I went with a New Frontier Carbon Lower. Rock River parts kit and Rock River BCM BCG. This complete upper lined up perfect with my lower and feels amazing. I’m loving the IRS rail system and the addition quick sling points. My magpul bugs CoWitnessed with my Aim AimPoint is flawlessly lined up. Can’t wait for my next build and try out your CQR stock!

    Purchased one of these uppers and the quality is good. I dropped it right on a lower and it ran like a champ. I would totally buy from these guys again.
