I haven’t personally done that, but have seen it mentioned on here that they’ll tweak your existing mags if you send them in. Not sure if they just bend the feed lips or actually upgrade the internals.

This atx was my first AI. Not sure I am in love with the comp trigger. I have adjusted it but still feel like the weight difference between the first and second stage isn't great enough for me. I prefer a light first stage and a heavy 2nd stage but can't seem to achieve that with this trigger. Do you guys think there is something I am missing with the adjustments or is that just the way the comp trigger is? The overall weight of the comp is fine I just wish I could take more weight out of the 1st stage and put it in the 2nd.
I have been considering trying to find somebody to trade me a standard AI trigger. Can you achieve a light first stage with a heavy 2nd stage (heavy relative to the 1st stage)? Never fired a standard AI trigger. Thanks for any guidance you guys can give.

I'm sure somebody will trade you a trigger here if you go through the correct avenue in the PX, or maybe meet up somewhere at a match etc...
I wasn't able to really get an accurate idea of my 1st stage pull weight, but it looked to be in the 14oz range, and then another 11oz to break the second stage. This is how mine came from the factory. Over 10 pulls, the combined weight stayed between 1lb 8oz and 1lb 10oz...which is about as consistent as you can expect from an electronic guage.
I do have a "very heavy first stage" spring as well as a very light one that came with my rifle. Have you tried that one to see if you like it more? If you need that spring, I'll be happy to send you mine as I'll not be using it.

Yea I tried both springs it seemed to just increase or decrease the weight in both stages. Assuming I have the same springs as you. Thanks for the offer.
Here is a short clip of swapping barrels and getting zero with my ATX and how dang easy and repeatable it is.

How long did it take to get your mags back? Sent mine in a while ago and haven't heard anything.
About two weeks

Do you have a weight on your setup with scope?
I don't...but could probably add it all up from the manufacturer specs.
Yeah I have a rough figure just curious if real world weight matched up to specs.
Took my scope off my .223 trainer and slapped it on my new AT-X for a few rounds of breaking in...which is mostly breaking me in to familiarize myself with the trigger and rifle.
I shot five to zero, and then (4) 5-round groups after a cleaning patch battle that cost me a new rod (mostly my fault).
I did chunk one low, but otherwise everything felt good.
Please don't mind the POI shifts, I let the rifle cool for a long time between groups, and the shift is merely me not getting back behind the rifle consistently between groups (was screwing with buttpad placement).
Unfortunately, I had a cleaning patch sick itself inside the barrel. The rod wouldn't budge either way. I noticed what felt like a rough spot on my first patch, but it made it though, and I attributed it to fouling. #2 got stuck worse than I've ever had one stick before.
^ Light tapping with a mallet got the rod through, but the patch was still stuck, and I had to tap the rod backwards (and I boogered up the threads on the way back).
Cleaned the patch out. Grabbed a .243 jag and tried again...could feel a friction point, and then the rod stuck again. This time I was able to pull the rod back out. Ran a wet bronze brush (CLP) through about 30 times and it patched dry without issue. That was after shot #4.
I then shot the four groups above over the next 90 minutes.
I'm probably going to run my borescope through the barrel in the next day or two, just to see if I find anything...hopefully I got whatever it was shot out.

But why were you cleaning ? These are quality barrels. Not Remington copper catchers.
The AI manual does call for a break in and lists their procedure. What does it hurt?
Patched stuck
Wear to rifling
Wear to crown
Wear to throat
Chance of solvent getting in action / trigger.
I’ve never broke in any Bartlien quality barrel and out of probably 20+ the only one that doesn’t shoot phenomenally is due to a terminus action issue
Let us know how the bore scoping turns out. Seriously...
Lol, the barrel that came on my atx was great for about 30 rounds, then it became so copper fouled it wouldn't shoot 1 moa. Clean it and good for 30 more. The throat looked like it was cut with a chipped auger and the rifling pulled copper from end to end.
I gave up on it quickly, it's a 25cm now.
Hmm. Who cuts these barrels now. ? Mile high ?Lol, the barrel that came on my atx was great for about 30 rounds, then it became so copper fouled it wouldn't shoot 1 moa.

I sold my atx barre cause I had piles from my AXSA. Ida figured the quality would be the same. Guess not
I only know it did not come from Mile High. I moved on pretty quick with the price of components.
Dude...I'm going to take some pictures.
I took the borescope to the barrel last night to try to see if I had a deposit or something where the patches caught.
With 20 rounds since my last patching and 25 rounds total...frigging copper the whole length.
Because I don't want to shitpost and disappear for the day, I'll throw these two photos up for now...I'll document better before and after cleaning tonight.
About like this from the whole way down:
And from about 2 - 6" from the muzzle, it almost looks like fire cracking. I know it isn't...but this is unusual. For reference, I have 3 Kriegers and a Brux here at the house, and I've never seen this before during break-in.
* I'm not super concerned. The barrel shoots fine. Hopefully with another 100 rounds and probably some frequent cleaning it'll hopefully fix itself.

I believe AI started supplementing Bartleins with Hawk Hills (due to shortages) in the AT-X last year. Does anyone know from any markings etc how to tell them apart? Not saying yours is necessarily not a Bartlein, but your pics make me wonder....

My experience isn't far from yours at the moment. I'll take better photos tonight...but there are a lot of tooling marks going into the rifling on mine too.
I'll add here too that I obviously didn't follow AI's break-in, so the fault lies on me. My patch did get stuck after round #4 though.

I have no clue on identication. I only know of what I've read on these forums, so I certainly don't want to accidentally trash a wrong manufacturer in my stupidity.
This one is a 5R. Does Hawk Hill make those?
Last edited:
I’d figure hawk hill is better than bartlien
Unless they cut corners to meet a price point or volume or something. Hope not.
Remind me not to talk about break in lol
Their site says 4 groove (so maybe that's the easy way of identifying) but I thought for sure I had a 5R Hawk Hill once upon a time (and I'm sure they'd be capable of producing 5R if that's what AI specified).
Has anyone seen a 4 groove factory AT-X barrel?
Last edited:
I'm going to count my lands/grooves on the way out. If it's 4, maybe Hawk Hill?
Either way, I'm going to edit names out of my post, and just put the number of grooves in its place.
AT-X 6.5 CM here. My barrel looks like the one diggler has. Shoots 1-3 moa using FGMM, Hornady 140 ELDM, a couple of Berger factory loads, and Lapua 136 scenar L. Chamber, grooves, lands look really bad near the chamber. FGMM 140 SMK keep it about 1moa.
Very disappointed to say the least.

I put about 400 thru mine and called it quits, it never got better even after lapping.

AT-X accuracy ?
Let’s hear it How’s your AT-X with stock barrel shoot ? Please post approx group size and year your At-x is (it’s either by the serial number or part of it ) Hearing bad reports Also post number of grooves in barrel of possible. I sold my barrel unfired as I had plenty from my axsa but...
www.snipershide.com I did not get to my barrel before I had to go help my wife at her vet clinic.
I will post a lot of pictures tonight. I might even record it and put it on my YouTube channel if I get the weekend to do this.
My barrel is shooting acceptable at the moment, so I'm not stressed. I might not be a fan if I have to remove the copper after every 20 rounds. I'd bet that I could get better than .6s with handloads if I wanted to chase this.
Fortunately, I have a 6mm, 29" Krieger blank sitting at the house, and Matt Stewart is going to use my stuff to set up for doing AI AT/AX/AT-X prefits.

This barrel definitely has 5 lands with the radius and grooves, and I have updated my previous posts accordingly. Barrel is marked "W7732" on the outside.
1) With the barrel shooting as well as it does, I'm not super concerned...unless it copper fouls again this badly.
2) Most of the issues seem to have come off with a decent cleaning. Time taken to get to the "after" photos was approx. 40 minutes and 30 patches. Right now ~97% of the copper is gone.
Here are some photos with 25 rounds total down the barrel by me. I'll try to list the photos with distance from chamber.
Rifling start at the lands and grooves:
6 Inches from chamber, nothing unusual to report really:
10 inches from chamber, turning into a copper factory:
14 inches from chamber, same:
18 inches from chamber, and this is where I got the patch stuck. This is where that cracking appearance really starts:
22 inches from chamber, less copper but more of that weird appearance:
Crown:

16ish inches in is where I found the only remaining copper:

Vudoo V360 in an AT-X AICS Short upper chassis, not sure if these are available anymore. Shorter front end, have to use the compact bridge.
I'm not a financial sponsor of the site yet, so don't want to put a link up however if you visit lowvisgear.com you'll find it.
The thumb rest is 3D printed by a local Aussie here, we helped with the development of that also, it's excellent and weighs about nothing. It replaces folder hardware however so the stock will not clamp down when folded anymore which isn't a major issue.

I was talking with an AI rep several weeks ago; he told me that the 5 groove barrels are all Bartlein blanks finished by WinTac, and the 4 groove barrels are made by Hawk Hill.
I'm almost positive mine is a 5 groove, but I'm going to double check.
15 more rounds down the tube today (40 total).
The first 10 inches have significantly less copper than last time (but round count is 15 and not 25). However from 12 - 23 inches it is still pretty heavy.
On the plus: including that almost new barrel CCB shot, my first 5 rounds went into .515". And my zero shifted all of .1 mil low with the barrel removal and cleaning...not shabby.
I'm still optimistic, but maybe a touch jealous of the guys who didn't have to go through this process

. So I couldn't figure out how I had the radiused lands with there only being 4.
Put my frigging readers on, pulled the barrel (had to clean copper again), then verified with my wife's 3x loupes. I then pulled my M24R out iof the safe and compared. Then I had my wife come and count to verify again.
This barrel is a 5R. I'm back and forth more than a middle-aged woman.
Sorry for the confusion. I'll go put myself in time-out now with the Savage shooters...

Some info, a person can get the LOP way down on these if you're willing to get a lil creative. I removed the adj but pad by fully unscrewing the thumb wheel on the pad. Then removed the 2 screws holding the adj butt height capture block in place. Took a pacmeryer 0.5" pad I had laying around from and old project, and used the to ai mounting screws to put it in place. I now have a 12.25", LOP where prior the shortest I could get was over 13". I removed both the gen1 lock screws on cheek and butt, and installed single knurled screws to its tool-less adjustment. I'm average height but in positional shooting from barricades and props I've found a short LOP really helps get steady. Hope this may be helpful for some of you!
1. That will really help when I get the kids shooting mine. Thanks for sharing.
2. Man, I thought I did a hack job trimming my Hoplite cheek pad
Shooter side is the "Hollywood" side where everything lines up! Function over form for me. Honestly the cheek pads from anarchy fit better than the hoplite ones so far I think.2. Man, I thought I did a hack job trimming my Hoplite cheek pad

Just picked up my first Ai atx. Couple things that I need some clarification on. First the over travel screw is not moving. I’ve tried heating it up without success. Do these come loctited in place?
The bolt that connects the qd socket towards the folder hinge arrived striped out. Is there a part number or what size is it for replacement.
Lastly the bolt lift seems overly heavy. Is that normal or does it just take time to smooth out?
