@Frank Green

Frank, how much clearance would you recommend?

I have a BB 1.25” blank. Gonna toss it in the lathe and just turn it to a smaller straight.

1.20, 1.15 or something smaller?

I think 1.250" might be too big and not allow enough clearance for barrel whip/vibration if the fore end is 1.3" wide. I think it would be o.k. but might be on the tight side.

1.200" you will be golden for sure. Plenty of clearance then.

So you could run a 1.250" breech diameter and either have a step down to 1.200" or some sort of a straight tapered barrel to get you down where you need to be.

Later, Frank

I’m working on a “kit” for the X. Basically all the tools you need to disassemble and reassemble as well as tork it all down.

Getting T handle stuff for coarse work, and fix it sticks for the torque.

I’ll update with pics and complete list once it’s assembled this week.

Really interested in this, I was thinking of doing the same. Look forward to seeing your setup and list.

It might not be any less expensive than just buying the long range kit from fix it sticks.

But I wanted a specific set that only has exactly what I need for this rifle. Just cause……well…..I don’t know. But it made sense at the time.

Small suggesting for future short nvg rail production:

Keep the rear the same length and contour as the long rail. I picked up a short to run 1.25” without turning barrel to 1.20. Since the only part that touches is further away from action during recoil.

The area where there is a gap is where I rest my thumb at times when grabbing front of rail.

I’d imagine others do as well. Not a huge deal. But seems like easy way to give end user more mounting options.

If this was already mentioned, I apologize. There’s a ton of posts here and I may have missed it.

 

[Darkside-Six]

Just a quick update on the magazine issue. Received my 2 mags back today from AI. Not sure what they did as I didn’t really take measurements but they both fit much better (tighter with less slop) and feed perfectly so far on both 6.5CM and 6GT.

 

[Feniks Technologies]

Final pieces for the purpose designed kit.

Will make a detailed post and likely a video.

 

[Feniks Technologies]

Pick and pluck foam always looks like shit. I’ll get a hot knife or some laser cut eventually.

I decided to leave the fixed T handles out of the travel kit. I have extended bits that will handle that job.

AW mag on top of closed case for scale.

 

[BuLLet]

Shot my new ATX for the first time today. Unfortunately I had feeding issues with 6.5 CM. Using the magazine that shipped with the gun and others that I already own. Push up on the mag and it feeds. Bolt now rides over an empty magazine, was the geometry changed specifically to allow that?

I've dozen of mags, am I suppose to send them all in and get them re-worked/exchanged for the ATX's? Why lower the mag in relationship to the bolt where you get these ride overs and no feeding. None of these same magazines have feeding issues in the many other AI's I own.

What's the likelihood with reworked magazines over time they will spread @ the lips/upper body and the problem returns?

By the way, even with the feeding distractions it shot lights out. Love the trigger. Got to get those folding hinges out!

They decided they want it to ride over. Pretty much all the explanation needed.

The body of the mag seems to have been the issue on a lot of mags and they are fixing them. I wouldn’t expect the body of the mag to change over time.

Personally I’m getting six AX mags that feed properly. Three will be used and the other three will sit on the shelf or in the case in the event of issues arising. I already do this with any other mag as you never know when you’ll drop one or something goes wrong.

As always, proper preparation and contingencies alleviate almost all problems.

Been following this for a while, I own an AT with an interest in getting an AT-X in the future, great guns and historically without equal.

Just to summarize. On the AT-X, AI wanted the bolts to override the magazine follower on an empty magazine so they change the chassis geometry and therefore created a potential feed issue and now it is a magazine problem?

Happy to be corrected.

I’d say at *worst* they made the system more susceptible to out of spec mags.

There will be 100 opinions what people think of it.

But, three brand new AX mags I bought run perfectly fine. And AI has been fixing or replacing any that don’t.

So, after that, it’s just complaining to complain about an issue that is resolved asap if it happens.

 

[Feniks Technologies]

Also, and I’m speaking absolutely hypocritically and in no way, shape, or form have any info from AI.

In the event that the small change makes the system more susceptible to a mag that is *out of spec* (meaning it’s bad already), there’s likely no way to have known that. You can only test so much. And it doesn’t make much sense to force a mag out of spec and test it…..because….it’s out of spec.

Now, if you have come across a situation where your past rifles would overcome this magazine flaw, that was basically incidental and not by design. Probably didn’t even know it was possible either way.

Now, let’s say it’s identified it’s more susceptible….this isn’t even remotely close to a recall or anything like that. A bad batch of mags got out and they are fixing or replacing. That’s all you can ask for.

If they decide later to change the geometry back, well, that’s just how it goes sometimes.


Opinions otherwise would basically be saying they should have designed a rifle to work with mags that are essentially broken.

 

[seansmd]

I don't think so based on Scott's comments in IM and I think here, there was discussion at AI and disagreement on if the bolt should be stopped by the follower or ride over it.

This is my only AI so I can't confirm behavior on other platforms with the same mags.

The bolt stops on the AX and AT. It doesn’t on the AT-X. Have owned and still have several here. You have to notch the rear inside corner of the follower for an AT or AX bolt to ride over an empty mag.

So, either the geometry/height was changed, or mags were changed. And it wasn’t the mags AFAIK.

Bought my AX in 2018 and the bolt never stopped on any empty mags. But it never had a feeding issue either like the AT-X.

[Feniks Technologies]

Interesting. I haven’t handled an AX or AT that does without the follower notched.

Probably 20 rifles. Guess that’s was too small a sample size.

So, never mind lol.

All of mine stop on a empty mag.

If I understand you correctly, you would like the short bridge to be able to came back to the receiver with no gap as on the full length bridge?

NO! The magazine positioning in the AT-X mirrors that of the AX. I stated in an earlier post that the bolt may or may not hold open on an empty magazine on the AT-X and AX series rifles. This is dependent primarily on the magazine. Some will hold the bolt open and some will not.

The feeding problem is well covered in previous posts.

The short bridge was always intended to be used in the middle to forward positions. If a zero gap is desired, the full length bridge will give you that.

Makes sense. The short rail *seems* to allow a 1.25” barrel to but run (as it’s further out that it touches when moved a bit) and still give a “handguard” as many of us use an nvg rail for.

Seems like keeping the rear geometry the same as the long would provide users with more flexible options via just having that extra 1/8” or so needed to reach the rear mounting holes.

Personally for me, no big deal. I’m just gonna toss it on mill and take of a little on the rear. It’s a tool that’s gonna get beat all to shit at matches anyway.

Thanks for clarification. I’ll delete my assumption posts. I just happened to get ones that it stops on.

I have a AXMC with a 6.5CM and 300win mag barrels, mags, and bolt combo. None of my mags induce bolt stop. Never have and I have owned the rifle since brand new for 7 years. I have about 10 mags in total (5 each). So I have been following this thread thinking are all 10 of my mags out of spec? Never have had any feeding issues whatsoever so it hasn’t been a problem.

My AXMC will stop the bolt with some brand new mags and not with others. 300NM/338LM/300WM/300PRC/6.5CM/.308. I've got the mag well adapter for SA mags, AXSR mags (no adapter), AX mags, AW mags, basically every compatible mag known to man...no rhyme or reason to the bolt stop function, it's all over the place. I just make them all non-bolt-stop mags for consistency.

@Scott Seigmund

I have an 2014 AT & 2018 AX. Not a AT-X so apologies if this isn’t the right place, however there is a conversation going on.

I do get occasional mis-feeds in both rifles. I’ve always assumed I’m short stroking or something and never paid too much attention to the mags or looking at the issue. (I don’t shoot matches and my life doesn’t depend on this rifle) With this thread for shits and giggles I decided to look at all my mags. 3 x AX and 3 x AT.

Loading up with 6.5 Creedmoor 3 x are perfect (all rounds sit square and level), 2 x show an issue and 1 ever so slight.

Now I’m not expecting AI to replace my mags as they are old.

However would you or anyone else be kind enough to post a DIY fix for mags. Which bits need to be bent or expanded and how etc.

Will you be using rifle on barricades and bags?

If not, IMO, the bone stock AT with folder is the best practical/tactical field on the planet.

You aren't the first person I've heard say this, what about the AT/AW stock is so good for field shooting?
I'd have thought a chassis would perform every bit as well.

No disagreeing, curious to know your thoughts.

More maneuverable and lower center of gravity than the AX without the hump in front of magwell.

I think it's a cost/benefit argument he's making. If you're not shooting off a lot of props, then an AT/AW will serve just as well (not any better), and it can be had used, to lower the cost.

 

[beetroot]

I can certainly appreciate that but I got the impression you think the AT is better as a field rifle than the AT-X, am I miss reading your post or is there something inherently different in a field rifle vs a comp rifle in your opinion?

LOL! that's not what I meant (sorry if it came off that way). What I meant to say more succinctly, was that Fenix thinks the AT-X rides better on barricades because of the lower CoG (which it does). I suspect Fenix's definition of "field shooting" equates to "field course of fire" (though I may be completely off) and means barricades, tripods, cow feeder fences, etc.. And your definition of field shooting is laying on your belly (right?).

So, cross talk in that manner. In that the older AT/AW is just as good a gun for laying on your belly in the field, as the new AT-X. And if you're not going to be shooting off of barricades (and mostly on your belly) the AI/AW may be a better option cost/availability wise.

Then again, maybe I'm the one getting crossed up with understanding the question...

The AT-Xhas a lot more parts. Doesn’t mean it will be an issue, but more parts is more parts to come loose, keep up with, lose, etc.

More parts means more tools as they aren’t the same size bolts.

The action can be unbolted. That means is susceptible to user error when reassembling.

The comp trigger seems to be ironed out. But again, many more adjustments and parts to the comp trigger than the OEM.

The chassis is bare aluminum. Which means cold. Along with some distinct metallic sounds of it hits something the wrong way. Sound is never good if you’re not looking to be heard.

The forend is much longer than needed for a non comp rifle. Depending on situation, this can be a hinderance.

 

[Scott Seigmund]

The AT-Xhas a lot more parts . . .

The AT-X has a lot more parts. Doesn’t mean it will be an issue, but more parts is more parts to come loose, keep up with, lose, etc.

Actually, the AT-X has fewer parts vs the AT and other AX series rifles​

More parts means more tools as they aren’t the same size bolts.

The current production specification for the AT-X utilizes a 4mm hex key for all the major components, adjustments, rails, and barrel change.​

The action can be unbolted. That means is susceptible to user error when reassembling.

The side clearance between the action and the upper chassis is minimal and all but eliminates the possibility of installing the action incorrectly. ​

The comp trigger seems to be ironed out. But again, many more adjustments and parts to the comp trigger than the OEM.

The adjustments on the AT-X trigger are virtually identical to those on the AI triggers. Accessibility to the adjustments is different between the two.​

The chassis is bare aluminum. Which means cold. Along with some distinct metallic sounds of it hits something the wrong way. Sound is never good if you’re not looking to be heard.

All modern sniper rifles are metal. This is driven by end user requirements that virtually eliminate the ability to use plastics and composites within expected cost constraints. We have much better gloves today than we did 35 years ago and I have couple of pairs expressly designed for shooting. But, yes. I would agree that metal is less friendly than wood or plastics in extreme heat and cold. ​

The forend is much longer than needed for a non comp rifle. Depending on situation, this can be a hindrance.

The AT-X is certainly not a compactable as the AX/SR series which can be fitted into a carry on bag or smaller along with extra mags, suppressor, etc. With a hinge installed, the AT-X can be nicely fitted into the Pelican Air 1615 case along with a tripod, spotting scope, shooting bags, mags, ammo, etc. ​
