Outstanding!!Review by Jeff
I cannot love Ballistic Advantage more. After getting the barrel for my first ever AR build, which was a M16A2 clone, I wasted no time putting it together. Accurate as can be and the workmanship is beautiful. I shall be back to buy more, you can count on it. Every time I hear anyone talk about wanting to build, I throw them the name of Ballistic Advantage. Inexpensive and loaded with value. What's not to like? ^_^ (Posted on 1/29/2019)
FANTASTIC!Review by Eiler
This barrel assembly arrived superbly well-packed and separated from the other components I ordered. The fit and finish of the barrel, FSB, and delta ring assembly were flawless, and I had zero issues installing them onto a BA assembled upper receiver. KAC M5 RAS hand guards installed without issue, and I'm quite happy with my new A4-style upper assembly. There were no issues between three shooters during break-in, and I'm officially on the BA barrel bandwagon now! (Posted on 9/30/2017)
