You changed your “tuning fork” so to speak. Caused stress to the action that initially wasn’t there. No different that removing a stock on a non bedded factory rifle like a savage or rem 700 which can change not only POI but accuracy as well

I blue loctited my action screws on my ATX when I had it. One screw was loose of the 4 that hold the action to the upper portion of the chassis. There was a few people who had action screws loosening up. I think the ATXC has 5 screws like the AXSR. My ATX had 4 and the chassis was very thin where it mounted together on the action

There is some play in that area. I actually wanted to bond mine but was talked out of it by a very well known guy on here due to the fact the chassis just wasn’t thick enough to bond in that area and could cause issues if you put the spacers in there. He suggested the blue loctite as a fix.

The ATX I think only torqued to 35 inch lbs (may be wrong) but that isn’t much. Not sure what your AXSR is but I think it’s a lot more if memory serves me right

After seeing the design and screws able to loosen up I went back to another AT rifle as I wanted the bonded action. The AXMC is bonded as well and won’t come loose either.

Not saying the AXSR will come loose. But if you broke the rifle down when new and torqued everything right away you likely make it more repeatable in the future when you break down and retorque it.

I will always be an AI luddite.

Bonded action gang.

GF reached out to the Tbac guys and got me this sweet AI patch. Technically its an AX50 with their new can, but if I squint it looks pretty close to my AXSR with SiCo/Recoil-X.

Unfortunately, this does not mean they're getting to my prize table cert Magnus RR order any faster.

I run the full size Magnus RR on one of my Dashers....It is comically quiet and a nice push of recoil.

I run a full-size Magnus standard end cap currently on my 6gt customs. It is very popular at matchs because its stupid quiet. Recoil is pretty nice when you're running a rig at 25lbs.

I was on the TBAC squad at Coal Canyon this year and got some experience with the Magnus K-RR. I was very impressed and have one on order.

Thought about putting blue loctite when I was torque it down. I guess I should do it next time around and zero again. Now more I appreciate my AX as it’s bonded. And more I envy the MC’s.. Because that #2 screw is also a bitch.

you will like it. S RR is my favorite but K works great on 6.5cm, 6.5prc. I enjoy mine all 3 sizes

Dont listen to @hafejd30 he is horrible with tools, and tricking you in. Small oversight happens. @hk dude has your explanation.

Didn’t you have an AXSR that had a loose action screw and you noticed it when the barrel seemed tilted in the chassis? At like 800 rounds?

I know it’s been mentioned before about loose action screws. I’d hope on a $12,000 rifle they’re torquing the chassis from AI. Otherwise the only explanation is they’re loosening with use. It happens. Other chassis systems like MPA and MDT have had issues as well

I also don’t feel I’m horrible with tools. I’m super anal about my stuff and I’m just speaking from experience and observations from mine and others who have owned several AI platforms.

I know especially with what it takes to access the bolts for the action on the ATX platform at least I wouldn’t want to or be able to check those bolts regularly. You need to remove the bottom half the chassis to do this

Guy rounded out #2 in this thread

AXSR Action screws

Hello All, How are you torquing the #2 action screw? It looks to me that you'd have to use a ball end bit but, wouldn't that make the torque required to meet the spec higher? Saying it another way, do ball end hex bits apply the same force to the screw for a given torque setting on the wrench...

Bonded action gang.

Bondage rules.

Don't know if that came out as intended.

 

[Roadrace33]

I’ve had the full size Magnus for a little while but I haven’t used it yet so I tossed it on the 6.5 barrel that came with this thing. It is really quiet, but to me it’s only a tiny bit quieter than the RR version of the same length. The S-RR is probably my favorite as far as all around use.

I got a couple recoil X brakes to try on them, everything I heard was positive so we will see.

So far, I absolutely love this XC…

at-x from factory, i tq'ed them and never had an issue afterwards.

 

[CStroud]

The hardest part I've had to try and install on these AI's is the dang mag release/catch on the atx. That thing is a bitch. It does seem AI kinda screwed everyone on the unbonded chassis bolt locations. Guess I'm spoiled from either having a bonded AI or 700 pattern rigs in the past.

Need to check them from time to time.

Not clear why AI abandoned the bonded chassis concept.

No different that removing a stock on a non bedded factory rifle like a savage or rem 700 which can change not only POI but accuracy as well

Looking at how an AT-X chassis is bolted together…I dunno, I’m no engineer but it looks less solid than an AT.

AT-X​

AT-XC​

AT​

Blue arrow is apparently where the front bit of the chassis attaches to the center bit. I believe this is also how the AX is put together (below).

AX​

For a non-bonded chassis like the AT-X/C, I guess it makes sense for the action to attach to the front rail so it keeps alignment with thermal/NV etc stuff. But with even six screws holding the action into the rail, there’s only two screws holding that rail/action assembly to the center part of the rifle.

I’m sure it works fine, there’s “stop blocks” of metal that help support the two screws. I’m not an engineer, just wondering what others think.

Edit: and maybe some know why these design changes (including not bonding anymore) were made. Maybe it’s partially down to the armorers and maintenance. Maybe this has already been covered…I have a vague recollection that it has.

This is a recent 20 shot grouping from my AX at a 100. On a bag, on a tripod. The 308 barrel has just about over 2000 rounds on it. I’ve never ever touch one fastener on my AX. Since I got the rifle brand new back in ‘21. AX is bonded. My AXSR action screw #1 & 3 got loose after 200 rounds. Could it be more recoil from magnum? I just wish the AXSR platform was bonded at least.

 

[CStroud]

If anyone is worried about there atx or axsr not being bonded, DNA firearm systems in NC offers a pin and bed service. I do not know if it works as I know no one who has had it done, just happened to see it on their Instagram one day.

 

[diggler1833]

Definitely had the two screws that hold the trigger in place come loose on my AT-X. Blue Loctite became my friend with e'reythang.
