Faxon ar barrel problems

[603Country]

Just get another barrel. A couple years back, I bought an expensive AR that wouldn’t shoot better than 1.5 inches at 100. I called the company and spoke with the CEO, who said “it meets MiL spec”. That didn’t make me happy. I bought a new barrel and am very happy with the accuracy.

Yes, if that's the correct terminology. It looks darker and polished compared to the area around it, whick look more cut or to have mild tooling marks. and it seems to have a wave pattern going up and down and an uneven start point to the lands. They all seem to start at different distances from the chamber in relation to each other or the chamber. The other guns i have looked down, of similar or lesser quality, appeared more consistent to me.

Sounds like maybe the chamber reaming was rough and not polished. I'm not certain about this--unclenick or scorch would know better--but I don't think an uneveness in the beginning of the lands and rifling are going to have much effect as long as the bullet is concentric to the bore on the way in. I'm STILL very curious to know if the entire barrel was nitrided, I've had a couple that had lingering "dark stuff" in the bore that was uneven even after 100's of shots.

Updated responses is post #19. They recommend i shoot without the muzzle device. And reccomended federal gold medal match. No comment on the issue with the leade. But i asked again in my response. And they mentioned replacement.

All in all, im not thrilled with the response time/ease of contact. But seems like they are willing to work with me at this point and i feel things are heading in the right direction. Will keep you all posted.

I finally looked up your barrel myself--and it is one that is nitrided from what I can tell so that probably is a big factor in what you're seeing with the bore scope. I'm kind of curious what the rationale is for the pinned low profile gas block; I've never seen that before in other aftermarket AR barrels.

It's for extra rigidity/strength. It's very common these days and something I have done on all of my rifles. Noveske, Centurion, DD, BA, AIM Surplus, and tons of others offer this.

I wanted a pinned gas block. And i did not have the necessary tools to properly drill and pin it myself. This is on my primary duty gun, and the idea of a set screw in a dimple being the only thing keeping the gas block from rotating or sliding forward causing the gun to stop cycling was not confidence inspiring. The low profile helps it fit under free float handguards better. And the pin ensures it wont rotate or come loose. An additional side benefit as it is pre-drilled for the pin, you dont have to worry about alignment. Just put the roll pin in tighten the set screws as a backup, done.

I didn't say I've never seen it done to an AR--I just have never seen it used as a standard manufacture feature of the barrel alone. I understand the logic behind the pinning of the gas block from a maintenance point of view. Would I do it? Nope--not a chance. You're going to be bashing away at those pins when it comes time to examine your port--or possibly even change a handguard barrel nut.

Assuming the port is properly clocked to the extension pin to begin with, I've bought a couple of barrels that weren't. Anyway, I've never shot my AR's in the role of selectfire duty so maybe that requirement is more stringent. My experience has been with the combination of carbon exhaust gases sealing gaps and solvents mixing--the block cements itself quickly to the barrel and I usually have a hard time getting it to budge even with the screws loose. Same kind of crud that forms at your muzzle crown that you'll find when removing a muzzle device.

Many of them use roll pins, which are removed quite easily. Definitely easier than taper pins used in fixed FSBs. How often are you examining your gas port?

OP,

If you're seriously considering just getting a new barrel, I'd take a hard look at this one. BA does have a 1 MOA guarantee, and all of mine shoot very well. This Hanson profile comes with a pinned block as well, and I've never seen them go on sale for this low of a price before. They still have a few other options in stock as well.

I need 2 more barrels over all. Looking into ballistic advantage. Didn't realize they offered a sub moa guarantee. Also on a wait list for a criterion.

[Shadow9mm]

I can verify, both the faxon and ballistics advantage use roll pins, not taper pins. Helped a friend install the roll pin on his ballistic advantage a few weeks back.

OP, you aren't the first to have issues with Faxon. BA has also had issues. For my recent 18" build, I was turned off by reports about both of them and others in the "affordable" barrel category. I decided to use an ARP 3R 223 W barrel from Blackstone. I've used 3 of their barrels in the past and they have all been fantastic. I'd give them a shot after you return that poor shooting barrel to Faxon.

All makers can have issues. Thats life, were humans, mistakes happen. But thats why custom services is so important. Help tge customer get to the bottom of the issue. If it winds up being the product, make it right.

Had not heard of blackstone, will take a look.

I can vouch for that, Harrison's barrels have been consistently some of the best AR barrels for the money that I've purchased and, as a consequence, I have quite a few of them. The worst of them shoots "very good." when he packed up shop and moved to FL for the "good life" I think he scaled way back on his involvement and that's when he subbed to Blackstone. I haven't bought any since the move--mostly because I already had most of his caliber offerings. He is/was especially interested in wildcats coming from 6.8 spc--and his 6.8 spc barrels still have a reputation of being some of the best in the industry.

I have an Aeroprecision rifle with an 18” heavy profile stainless, .223 Wylde 1/8 twist BA barrel that’s been a consistent .75 MOA shooter out to 300 yds. It was basically an MOA rifle up to around 500 rounds and then it started getting better and finally settled at .75 and sometimes I can even get a sub .5 MOA group at 100yds.
