Accuracy International AT-X

So, like some others, I've been having the bolt ride over the rounds with various magazines. With all the magazines, the bolt barely touches the mag follower. I think some of our mag catches must be a tad short. I tried Bravo6niner's solution in post 2337 of loosening the bolt catch assembly, inserting small shim strips and retightening the assembly. Looks like a good temporary fix, as all my rounds load fine now.

Which gen do you have ? Gen1 or Gen2 ?

 

[MarinePMI]

Mine is a Gen 1.

 

[TomekA]

The action, bolt and magazine are the same (exact the same size ) as in the AT or AX, aren't they ?

Magazine catch is attached to the new chassis.

 

[Katana88]

Mine is pretty early production, so Gen 1.

 

[deersniper]

The next production run will start delivering later in March and will run through April and May. After that the next AT-X rifle with the new rear end will start delivering in July 2022. It will also be possible to purchase the new rear as an aftermarket accessory which can replace the current rear with the Allen screws, around the May/June timeframe.
We do not give any preference to our distributors regarding deliveries.

ETA on hinges?

It is less than ideal to have no hinge, Allen head cheek piece. Have to wrench on cheek piece to remove bolt

 

[DocRDS]

I know some of us were bitching about stuff but in a cool story bro (somewhat related) a biathlon rifle at 5k comes WITHOUT the rear sight. (and they are meant to be shot with open sights).

But I bet they released with a hinge...

@Scott Seigmund will the bridges in the elite sand become available when version 4 of the chassis is released?

Since the manual does not have torque specs, before I disassembled the AT-X I made witness marks on everything I could. On reassembly I double confirmed torque with Fix-It Sticks AND a Craftsman Torque wrench. I went to the range this afternoon, and the first five rounds printed ~1/2” group with no shift in zero from disassembling the rifle. I debated posting this, but I figured the torque specs could help others. I do not work for AI, and these are just what my rifle toque values were. Anything that does not have witness marks was torqued to hand tight + 1/4 turn.

Man that looks sexy! @blbennett1288

I need to find some weights for mine. Everybody seems to be out of stock.

Thanks for listing this, it's going to be helpful for us vintage AT-X folk.

Dependabilt weights are in stock

If you have to have the WIN-TAC weights, I’d call whoever you ordered it from and tell them that you would like some weights. They typically have them in stock and only sell them to people who purchased the rifle from them.

Yeah been looking at the dependa ones. I have those for my AX and like them. I didn’t get my ATX from a vendor. Had a buddy that got the first run and then didn’t want it. I’ll call MH and EO tomorrow though. Thanks.

 

[TomekA]

What muzzle break is on the AI AT-X rifle in the AI Specification Sheet ?

 

[trob_205]

Anyone know the shortest barrel length that can be installed on the AT-X rifle?

 

[MarinePMI]

Anyone know the shortest barrel length that can be installed on the AT-X rifle?

Just running a quick carpenter's tape against the existing 24" barrel, I'd say 18" is about as short as you'd want to go.

 

[Lonely Raven]

I have an 18" .308 barrel I picked up lightly used for my AT-X; it sticks out just enough from the handrail to allow a suppressor to mount without interference.

Another low-profile option. GRS bag rider. The machining, size, and color make it seem like it was made for the ATX. The lower profile rider on the ATX is great for an average size rear bag. Got it from euro optic for $80ish. have this on order

Finally had it show up today in time for some range time this weekend.

I’m not entirely sure if this mount is going to work out, but we’ll see. The cheekpiece is currently bottomed out with the 4601, so I’d suspect the 4602 might be necessary, especially if I can add the fore end bridge.

You guys may be getting NV bridges for a different reason, but for me the utility is to be able to attach a top rail (for NV clip-ons). In which case one also needs the tall action rail and a 1.5” mount to line up with most clip-ons. That should alleviate any cheekpiece height issues, but it does raise the optical axis height quite a bit (ala AX and AXMC/SR).

At least it isn’t as high as the Cadex duel stike chassis. it’s like installing your optic at the top of a ladder

Well, yeah, there's that discussion, too.

The usage of NV/thermal clip-ons here is pretty much non-existent, being in Canada, so it would be for purely aesthetic purposes.

Need a neck extension for one of those monstrosities.

^^no one in Canada shoots with clip ons?!

They used to but all the batteries are stuck on trucks in Ottawa

That’s true, though it looks kinda odd without the picatinny rail up front. Which is of course out of stock everywhere.

I won’t speak for all of us, but I would wager that it is few and far between.

Funny...I prefer to only shoot at night these days

 

[Bravo6niner]

Did up a mag extension conversion tonite. Functions well so far. 12rds fit nice with a touch of room to spare. Used an altus +2 extension

 

[Heffo]

Never been so organised for a rifle. Shout out to Sporting Services UK for delivering the goods to Australia faster than our domestic services over here ATM….and the HRD kits are literally half the price too. (And rare over here) Can’t wait for the AT-X with a couple of extra barrels (6BR and 308) cheers.

How much of a pain in the ass was it cutting off the bottom plate? Makes me a little nervous cutting off the bottom of a perfectly good magazine. Hahha

5 min of Dremel work and you're done. And u dont cut the bottom off, u basically cut out a hole a little bit bigger than the last follower spring leaf and put it back inside and make sure the spring goes down through the hole.

Interesting. I figured you’d just cut the welds off the edges of the bottom plate.

 

[Bravo6niner]

I just cut the welds and took the whole plate off. Cut some slots to bend out two new tabs and then trimmed everything up flush. Doing it this way leaves everything inside the mag body flush and smooth. After doing this one I think if I made a couple jigs you could modify a mag in 10 minutes

Make a “how to” video on YouTube.

I’m picking up another mag today so I’ll take a few pictures of the next one.

It's a joke, I don't care what people do with their mags lol I just run a +2 deal on the side of the chassis. If the majority of stages turned into a 12+ round stage, I would probably chop up at least one mag for this sake.

 

[BLKWLFK9]

I can't remember the last match where there wasn't a 12rnd stage. Ive got the 12rnd .308 based mag running good, but if im shooting dasher, im stuck to 10rnds and a +2 on the side.

You need to shoot out west more then

Are 12 rnd stages that rare out there? We get tons of 12 rnd 90 sec stages here.
