Accuracy International AT-X

I jumped ship to an AX and ordered an AO chassis in the end.
I did the same too. Only I didn’t put down for a ATX. I wanted a ATX for my first AI. But being that lead times was too long, I settled for a new AX instead. AO? Well I have to at least beat the crap out of the OG AX chassis first since it’s new. Besides, it’s like tank built. And in ES..

Does anyone know how much height the high rail adds over the stock low rail? I bought a bridge and have a TigOR-6z+ that comes with 36. 38 (1.5”), and 39mm (1.54”) height mounts. It also will accept some offset as long as it’s collimated.wondering if I could get away with the 36mm mount. I use a 1.5” spuhr 4002

If your action rail and night vision rail are coplanar then it doesn't matter how high the rail is... If your day optic is 1.5 you should be using a 1.5 nvg mount

Sorry should have been more clear. I have the stock low action rail. Trying to get away with not installing a high one. But I can get lower mounts for the TigIR to compensate for the low action rail. Hence my question of asking the height difference. I’d say the difference is 2mm then I can simply use the 36mm mount. If it’s 4mm I can buy a 34mm mounting plate etc

To that I say.....

Lol it’s not about being poor. It’s about the PITA to break it apart and retain the factor bond and recoil lug for the rail. AI seemed to overtighten a lot of the screws on my Gun already to the point of stripping them.
@deersniper I'm pretty sure is running a low action rail np

Also what’s the part number for a full length 20 moa rail for the full ATX bridge?

Edit: does AI make a short rail section that’s 20 moa to match the factory rail slope pitch? I don’t need and would prefer not to have unnecessary extra weight of a full length top rail

I heated the crap out of the hardware and broke the thread locker bond by using a cheap bit to lightly hammer the screws.

Purchasing this below will include the correct hardware and recoil lug/pin:

No, they do not make anything that matches the low action rail.

Another option, which I did, was use the AT high action rail with the AT 20moa NVG bridge rail.
 
Sounds like this AT 20 moa rail would be the best bet and pretty much exactly what I’m looking for. Will try it out with the low action rail. Apparently the TIG-IR is pretty forgiving with height. I’ll collimate it and shoot it out to 500 dialing to see how it works before I go on the science project if swapping action rails. Thanks!
 
They appear just black oxide. Nothing crazy. The black oxide screws (carbon steel) are usually the hardest commonly available commercial grade small screws.

The accessory rails are about the same height as the AT 20moa nvg rail. The accessory rails are shorter than the ATX full length 20moa rail.
Good info thanks man! My clip on is pretty small so don’t need a lot of rail real estate. I’ve got some linger accessory rails that would work too but I’ve got a feeling that the 0moa of the accessory rail may cause issues with the clip on and the 20 moa factory action rail

Not in my experience. My AT-X high action rail came with no recoil lugs and the attachment screws were way too long.

My recommendation is to still go with the AT-X high action rail, swap the recoil lugs over, and use the corresponding AT-X 20MOA NV rail. Doing anything else just increases the number of potential sources of error.

I know I saw it earlier in the thread, but I’m too lazy to look… what’s the lightest config y’all are getting out of these with a carbon barrels or similar?

Obviously dependent on scope, accessories, etc. but any hope for Open Heavy Hunter class?

Not an ATX but it’s possible. I’ve seen team AI guys run open heavy at the NRLH finale last year with an ATX. Nx8 4-32 and tbac bipod.

Atx Specs say 13 pounds? Should be plenty of budget fkr scope and bipod especially with a fiber barrel
Yes, but it’d probably get a little squirrelly with a suppressor (since I’m civilized) and depending on chassis accoutrements (folder, NV bridge, etc.). I understand all of that is remedied by removing stuff, but was more interested to see if anyone had set one up one similarly and what it weighed in at.

Because you probably ordered AI-29394BL and not the one I linked.

I know my rifle which has a zco420, heavy ass unimount, mirage shield, barrel tuner and supressor, Ckyepod weighs 20#. Remove the tuner/can in favor of a titanium brake, cuts a pound, run a carbon barrel, cut 2.5 more. That puts me a half # over open heavy. Switch to a sub 2# optic in lighter rings you'll make weight. The rifle will be very ass heavy. My rifle config at 20# with can tuner and Ckyepod oit front balances perfectly in front of mag well.

What’s the re-sale value like on the at-x’s?
It’s going to be hard to compete with these sweet prices

As @NoLegs24 already pointed out @MNTC has them for $4670. There was one that sold a couple weeks back with 2 barrels for $4375. There was one for $7k but it came with a custom camo, weights, magazines, 2 barrels, and a AXSR rear end.

6.5 PRC ? Very soon, 2024
I just read the other thread where Tom Irwin said the team AI guys spoke out of turn at the AT-X release and they aren’t planning a magnum or 223 bolt anytime soon.

DAMNIT! Is it too much to ask to run a 7 SAUM and a 223 Ackley in an AT!?!

Ahem. Now to price out a bugholes setup.

You are absolutely right, I checked my order and it was in fact AI-29394BL. I didn’t know there was a second option available, is this a new offering?

This brings up another question, why are there two different options for the same rail? Who would want one without the recoil lugs and correct hardware?

Mines actually surprisingly light. Go with a 22” (with can) or 24” (without) carbon barrel in 6 creed or similar. Still nowhere near a manners and carbon barrel but it’s respectable. And the weights feels like it’s in the right places.
