Ballistics Advantage - Barrel Autopsy

[@BallisticAdvantage]

Thank you for putting together such a thorough video on barrel inspection. As you stated, while we demand the highest standards in quality with our manufacturing, we would be remiss to say we are perfect. However, we stand by our guarantee on our rifle barrels to give sub-MOA accuracy. As such, we would absolutely replace this barrel for any customer. Please give us a call.

[@SchooloftheAmericanRifle]

Ballistic Advantage, Thank you for taking time to watch the video and post a reply. Great response as well.

[@dancarter7009]

And that’s why I still support BA!🤙🏻

[@ricks.1092]

Ballistic Advantage is the only barrel I use in my AR builds. I recently used their 14.7" pencil barrel...which is quite accurate, light weight at 20oz. And the gas block is pinned with set screws...comes this way from BA. The entire build is bomb proof, light weight and shoots well. I think the entire AR is 6lbs and 6 oz with an MRO optic on top....add another lb. when there's a full mag. Mags usually weigh about 4-5 oz and 30 rounds comes in at 12 oz.

The gauges don’t lie!!! during our two day course at SOTAR we had Aero Precision/Ballistic Advantage barrels completely within spec, while there we factory new Hodge & Noveske barrels that were out of spec , so much that we had to recut the chamber on the Noveske to finish the build/class. Great learning experience!

Years ago I bought a ruger single six made in 1954. Wouldn't group at all... Come to find out that the barrel was completely smooth and shiny. I really doubt that someone shot it so much that there is zero rifling left. I always figured that it left the factory that way.

[@c6quad3]

I bought a BA barrel and they sent me the a 6.5 Grendel instead of 223 Wylde that I ordered. I called them and told them about the mistake. They immediately sent me out the correct barrel and said I could keep the other barrel for a future build if there's no return label inside the correct barrel package. No return label was inside the box so I got to keep the incorrect barrel. Can't beat that for customer service! The fact that they immediately sent me out the correct barrel without having to return the other with no questions asked speaks for itself. Very few companies would do that!

[@seanoneil277]

Thanks Chad. What an awesome thing to discover. I bet you did a double take when you first noticed, "no rifling here."

[@njw1977]

This barrel reminds me of that rifle that Franklin armory came out with a few years ago where the 10" barrel didn't have rifling to try to get around the NFA.

[@2ATac]

My shop, 2A Tactical in Barrington NH, has been selling and installing Ballistic Advantage Barrels for 8 years. We've been extremely happy with the high quality of their products. I've had several conversations with Clint Hanson on the phone (despite never meeting him in person) for relatively minor issues, and he's fixed them immediately. Even the best companies have things that fall through the cracks. And even the best QA / QC programs miss something once in a while. I see no issue with your video Chad, you are addressing a serious flaw. And I think you handled it properly and responsibly, as a learning moment and as stated, as a sample "of one." Clint stands by his products and will continue to learn from rare issue such as this and will keep moving forward as one of the best manufacturers of AR barrels around. -Rob Russell, Owner, 2A Tactical LLC.

Great for rat shot 22 or with the conversion kit, Henry makes a smooth bore 22lr just for that reason. Not to mention all the other experiments you can do with it. I'd still want BA to send a replacement, or sell me a barrel at the cost of materials if I could keep the smooth bore.

Looking around various forums I’m not alone in my experience either.

Good job Ballistic Advantage. That is a very advantageous barrel. As soon as you said so far everything is good by brain was like "well he said autopsy so there must be a rifling problem" i didn't expect that though. There can't be a problem with the rifling if you don't have any i suppose. Im sure ballistic advantage would replace that barrel no question asked. If they wouldn't then i would never buy a barrel from them again. I usually get Faxon barrels for fighting rifles and white oak armament for SPRs and such, but i have installed a few BA barrels for people who request them.

BA is solid company and I use the BA Hansen profile exclusively.

[@jenniferstewarts4851]

it was found that HEAT rounds fired out of a rifled barrel would wobble in flight and because of the spin not hit correctly every time. This barrel was obviously made to fire the 55.6 mm HE and APDS rounds. As opposed to the 76.2mm. (yes i'm being silly)

[@phosistkar6425]

oh my, I did notice when you were running your bore-scope down the barrel that I didn't see any rifling. I figured the scope was just too close to really be able to see the lands and grooves. That's amazing, I have to wonder how something like this even happens? As I recall Balistic Advantage barrels are button rifled so I wonder if an un-rifled blank somehow ended up in the stack of already rifled ones and made it all the way through the remainder of the processing without someone noticing.

[@seanoneil277]

It's got to be a process step oversight, as you suggest. In all human manufacture such things can happen, and even an automated process line can make mistakes! BA undoubtedly would fix this issue with a replacement barrel.

[@MichaelPetty]

I used to work as an inspector for a machine shop. For large quantity of items, you normally do a percentage check on dimensions that have large tolerances, and only 100% inspection on things with super tight tolerances (Like 0.002" or less) unless the customer requests and pays for 100% inspection. I have seen parts come back from heat treatment where they missed 1 part, but had we not done 100% inspection (heat treat is easy as it leaves scale on the parts), it could have slipped back into production. I have also done inspections where a part had a +/- 0.0002" tolerance on dimension, and out of 200 parts only 1 failed. For something like this barrel, it could have been as simple as a shift change, and the person running the rifling pulled a part out of the machine without having actually been run and threw it in. Afterwards all other milling was performed, and this barrel didn't make it into the final 20% check (or whatever % BA uses), was checked for some other dimensions like thread tolerance and gas port hole diameter, and then got packaged and sent out. Some manufacturers like Foxtrot Mike do a 100% inspection on every barrel, which reflects in the cost.

@@MichaelPetty Thanks for the explanation, this particular barrel is from their Modern Series which is their lowest tier of barrel so I imagine they check a lower percentage of these barrels than their more premium barrels so it just slipped through the cracks. It does go to show though that the barrel passed every other check quite well so this is pretty clearly a fluke. While I'm sure Ballistic Advantage would be happy to replace this barrel I'd have a hard time not holding onto it if I got an un-rifled barrel just for the novelty of the thing.

[@onpsxmember]

More nuggets for the collection. It's a good idea to mention the manufacturer. That way one knows what to check first and there is no 100%. low single digit failure % is all that's achievable and often it's out of one's hand. Let's all works as usual of the production but the base material has a slight variation in a batch and there was a short delay in the heat treatment process or with a coating and already tolerances are stacking. More of that!

[@XaviarCraig]

Indeed every company occasionally messes up... Unless you go into the High-Rel lines of products in which case you spend like 200x more for a part or product knowing it's been tested again and again in every imaginable way. Regardless, thanks for the video once again. Its always good to see a break down of all the areas of AR parts we should inspect! I actually have a few Ballistic Advantage barrels. While they are not the best, they always seem to perform very well with most M193 and M855 5.56x45 ammo and they seem to hold that accuracy longer than most comparably priced barrels.

[@claywynn4507]

Express any concerns or pertinent tests of the neat to ragged hole formed in the bore by penetration of the gas port. As a retired machine design engineer, spending good portion of life in a precision machine shop, I say scraping a portion of bullet jacket on its path down the barrel by a ragged port intersection can cause variation of flight accuracy. If borescope view shows a marked deposition of brass on the downstream edges of the port, then clearly some of the jacket is being deformed and scraped and deposited.

You need to make a gauge to check the distance between the bolt face and the chamber face, when in battery.

I bought a criterion CORE series barrel and found a chip in the feed ramp. Everyone I talked to said it wasn’t a big deal, even the manufacturer, I still however sent it back and got a full refund. Manufacturer let me keep the BCM BCG for free. One of the other reasons I sent it back was how over gassed the barrel was but that is a manufacturer decision on what port size to use so I don’t hold that against them. More of preference with me.
