Best basic barrel ever...Review by IntelMerc
Full disclosure, I purchased this barrel from another authorized dealer for a great price.

I mounted this barrel into an Aero Precision M4E1 upper, surrounded it with an AP 12" enhanced quad rail, and capped it off with a KAK flash can. I have a BA NiB BCG and a BMC medium charging handle. The complete upper looks sweeet! The muzzle just pokes out of the rail by a 1/2 inch. It's perfect!

I mounted the upper on a closed ear Anderson lower with a SB3 brace, ALG A.C.T. trigger, and a Magpul K2 grip. AR pistols are great, but the typical 9" rail don't work for me. The 12" rail keeps my support arm straight, while my primary wrist is straight using that K2. A wise man once said that "straight lines are strong...".

After getting on paper with a Primary Arms 1x Cyclops at 50 meters, the accuracy with this 10,5" 5.56 barrel was immediately evident with a 1 inch triangle group using my plinker 55gr handloads.

200 rounds later, I was tearing a ragged hole into a 3x5 card at the 50 and 100. What more do I need from an AR pistol? (Posted on 3/13/2019)

Dragon StickReview by Dave
Outstandingly satisfied!!! Fit and finish are extraordinary. I purchased the pinned FSB additionally. Everything arrived as expected and I am very satisfied. Configured everything into a pistol setup and my first few shots were surprising. Currently, ran 150 Wolf steel cased .223 cartridges, flawless operation. I expected some initial hiccups, but I did not encounter any such issues. Also, Ballistic Advantage's lightning fast shipping makes them a first rate, top tier firearms manufacturer and distributor. If you are on the fence about purchasing any of their line-up, don't delay. As soon as they are available, their barrels ship out fast. (Posted on 10/2/2017)
Pixie DustReview by keith
I wanted to drop you a line to tell you guys how amazingly wonderful these products are! I just finished a 5.56 pistol build on a spikes Crusader lower. Once the barrel with pinned gas block and Bolt carrier group was unpacked I knew I was dealing with an item the company took pride in. This is my life or liberty weapon and I needed it to perform, not so much cosmetic but it NEEDED to perform for me. My life and the lives of those I love depended on this. I have used Daniel Defense products and many others that made claims to be the do all be all of the firearms market, only to be left with the "Meh" feeling. Once I got beyond the quality feel and finish of the parts and got it assembled I knew headspace was not an issue at all. There was no need to check it, it just was right. The parts mated together like a foot sliding into a tube sock. I loaded a mag and stepped on the range and it was like the stars aligned! Pixie dust was sprinkled! Your barrel and bolt mated to the PWS CQB Compensator were like falling in love the first time. I would have paid twice as much as I did for these items. It performed way beyond what I had expected! It almost made me feel like I could be arrested for lewd behavior. I told a buddy, "Kelly you have got to come shoot this thing!" It hits at 1/4" group shot after shot. Most short barrels you would pay three times this much for won't ever perform like that. After combat tours galore this was the weapon system I have been looking for for years. The next build will be a 300 BLK upper for this lower. I am never the type of gun guy that raves over one company or another. I am an equal opportunity pessimist until I find what works. I am not the "Tacticool gun guy." I am a realist and an AR purist. I am now a Ballistic Advantage fan boy. The pinning of the lo-pro gas block ya'll did for me was exceptionally done! I cannot wait to start building this BA 300 upper if you guys make it I will buy it! Hell, I'll even start wearing Ballistic Advantage swag and I am so not a swag guy. But anyone who asks I will tell them to "go BA or go home" Daniel Defense who? LWRC what? Sorry bro, can't hear ya' I'm spending time with a real weapon!
Hopefully waiting for you guys to build a compensator like the PWS CQB. It is absolutely necessary for a short barrel Can never figure out why guys build short barrels only to defy its purpose and have a concussion machine. Build it right Go Ballistic Advantage!

Faithful Ballistic Advantage Shooter and builder for life.
