(1) The 16" barrel was bought only because you did not have any other length (18, 20 and 24 are never in stock and cannot be special ordered)!

(2) It appears to be returned merchandise. There were scratches on the gas seat area, the dimples on the gas seat for the gas block set screws have scars inside indicated that the gas block had been mounted then removed. The gas tube was notched near the receiver end. The cylindrical cardboard container was crumppled on both ends. None of these are show stoppers but it was clearly NOT in mint condition.

It looks fantastic and very well built. I have yet to fire it, as a matter of fact, it's not even fitted to the gun yet. So there by I can not "Love It" as I do not know how it will shoot. and function in the complete build. (Posted on 11/23/2016)

This review is for the 16" version of the Christiansen Arms CA-10. I want to build a lighter weight version of a previous build I had completed. Out of the box the the quality looked to be on par with the price tag. I thought it was great that it came with it's own gas block that comes pinned and set screws and gas tube. Which neither are a proprietary size so it was nice touch. The crown and the threads of the muzzle were clean and had a great finish. The barrel extension fit well (not too tight, neither loose) into the Rainier's billet upper. It has cycled every type of round I have fed it without even the slightest hiccup. After 380 rounds I can say with confidence that it's a great shooting carbine. 168gr and 175gr Fed Gold Medal Match shoot incredibly well through it. Both have a very predictable cold/clean bore shots (1" high, 1"left @ 100yrds) in this barrel. And shoot well below 1 moa. (Consistent .675" @100 yrds with 168gr FGMM). (Posted on 11/1/2016)
Great after tuning a littleReview by
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)
