Hey guys, I could really use some help as I’m getting conflicting answers through my research online. I’m looking for the measurement from the face of the upper receiver to the shoulder of the threads on the 8 inch RDB barrel. I’m trying to do some math for a hand guard and muzzle device, but can’t seem to get a straight answer. I even emailed CMMG but they couldn’t give me an exact measurement from the receiver face to the thread shoulder and could only tell me that their 7 inch hand guard ends approximately 0.25 inches before the start of the threads. Any help would be greatly appreciated.
