I had finally purchased the K9 barrel that had been on backorder. I had been looking for an upper and handguard. I decided to stay with Roscoe. I ordered this upper for my AR build. I have already put over a hundred rounds through it. It is solid made and functions like it’s supposed to. The Roscoe handguard I purchased with it was a perfect fit to the upper. I am completely satisfied with Roscoe.
