Accuracy International AT-X

More fun with the AT-X. This happened multiple times with factory Lapua 6 BR 105 Scenar ammo and the HRD kits. AX mags.

I’ve tried emailing @Scott Seigmund and calling AI about that other AX mag that didn’t work after they fixed it, no replies.

To be fair, this looks like more of a mag/ammo issue than an AT-X issue. Modification of a factory mag, albeit reversible, for use with a short BR round.

Have you tried to run this in an AX?
 
I had the same issue with both my AW mags running HRD kits for 6BRA in my AT. The second to last round would nosedive under recoil. I tried stretching the spring, but ultimately ended up making an anti tilt by cutting the follower and adding a sheet metal tail (mimicking a magpul m4 mag follower).

This is the reason I got rid of my BR and Dasher Barrels…

Would nose dive after 7th round, in 2 AX’s.

HRD’s response to the issue was comical, when it happened a few years ago.

FWIW I run a 6BR in my AI without issue. Whole 2 day match PRS fed flawless in dusty ass Arizona. AWs with HRD kit. So it can and has been done. I use those same mags in my Vector in a KRG W3, JAllen, and many other chasis successfully with the BR and BRA.

Fair enough. It just seems to me that there are just as many negative experiences around feeding with the BR variant rounds as there are positive stories, such as yours.

Some guys just get lucky, I guess.

I have an Impact that has never had feeding problems with Dasher, BRA, 6.5 CM, 6 CM. And I have an AT-X that really only feeds 308 reliably, or maybe the Creedmoor cartridges from AW mags. And AI is unreachable. I’d like to have this thing work out, but my optimism is fading.
 
See, I thought one of the big things about AI was that they respond...hmmmm. Im gonna knock on wood for luck.
AI isn’t the company that won the British sniper rifle contract against all odds. They’re the company that lost the ASR contract. And it shows. At least HK’s contempt for their customers is tongue in cheek.
 
The forend is much longer than needed for a non comp rifle. Depending on situation, this can be a hinderance.

I wholeheartedly disagree. Modern tactical applications require the use of long NV clip ons, which require a long forend when used in conjunction with a modern full-size scope.

You could maybe make the argument that AT rifles are more practical for casual, daytime shooting, but that's just not the case for actual tactical applications. Every rifle I've been issued and used professionally (Remington M2010, MSR, and a couple of other specialty bolt guns) use chassis that look a lot more like the AT-X than legacy AT rifles. The design is driven by contract requirements, not style.

Scott, I'm gonna plagiarize a couple of your pictures from Range 37 just to illustrate the point.

The below is a lot harder to do with an AT rifle than AT-X. Note how even with the extended forend length, there is no remaining rail space left up front with the ADUNS and HISS.

For every example you can give, I can show you a .gov/.mil or agency running an AT or shorter forend.

I also qualified several times that speciality rifles were excluded. Most agencies and other such entities aren’t running a HISS.

Keep in mind as well, just because a contract asks for it, doesn’t make it practical.

I promise anyone here who works/has worked for any fed/state/local/mil has gotten some absolutely retarded shit that was spec’d on a contract.

Hell, there are current requests for ELR rifles for man sized targets where the hit % is ridiculously low. It won’t be long before people are claiming that’s practical because .mil uses it.

Was designed by someone very bright and very experienced. Seems if aluminum everywhere and all those other “problems” were a problem he would have done something different
 
Until your 18 and 20” barrels with can won’t fit.

State/Local don’t require a 24” or longer. Granted, many are moving to gas guns.

Also, Terry will still sell a ton of regular sentinels. Not like he’s tossing out the old design. He’s widening his options.

We are literally arguing over preferences here. I merely gave mine which many share. And I see the other side as well.
 
No. The flat edge goes to front of barrel. That way the full length rail on the fore arm (if he were to put one on) would be flush to the action rail.
I’m going by all the pictures Ive seen of the short rail. Early pics from AI. Plus, it’s a short rail and barely 6 inches. Only rail I can find for it is a 5.5 inch rail. Otherwise there is a 7 inch rail that would be too long.

But yeah Whatever you like

Lol. My bad. I thought you were talking about the actions rail. One end is curved. Now I realize you’re taking about the front bridge. 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

My bad.
 
Is it not pinned like the stock rail?
It is, but the pins are easy to swap.

My AT-X high rail didn't come with the pins so I swapped them out from the low rail. All you need is a punch small enough to fit through the top holes, easy peasy.
