Great after tuning a littleReview by Jason
Nice barrel once I got it to cycle my ar-10 style rifle. The 20" barrel came drilled with a 0.061" gas port which was not big enough to flow enough gas to cycle the bolt. Christensen Arms' website says the other option is a 0.082" port. After drilling the port out to 0.082" the rifle is accurate and cycles through every type of round I've fed it. (Posted on 8/28/2016)

It's installed along with the muzzle brake I purchased from you. I had to mill out an area on the top of my Armalite OEM hand guard to clear the gas block to make it fit. Otherwise the install went fine. I'll give it a good cleaning tomorrow and go to the range next week to break it in. I will let you know after the break in (Posted on 8/20/2016)
