Does anybody have the weight of the atx or Atxc without a barrel? Or ideally without a barrel,bridge and bag rider? Trying to spec out a a build to ride just under 16 lbs. ThanksView attachment 8711659
The AT-XC without a barrel is 8.2 lbs, that’s with the bridge (11.6 oz) removed and the factory bag rider replaced with the Bug Hole version. I just set one up for NRL Hunter open heavy with a 7 SAW carbon fiber barrel (3.4 lbs), Vortex LHT, and Cyke double pull and its right at 15.2 lbs.

How's the balance on that setup? Right at front of mag well with bipod attached?

Also is the bolt opening and closing forces truly noticlbly lighter than the prior gen atx's?

The rifle is pretty well balanced but a bit tail heavy. 1-2 sets of external weights (depending on the barrel contour) and she’s just right for me.

With regards to bold lift don’t have experience with other atx but don’t find much difference with the axsa.

This may not be 100% accurate, but it’s worth something.. I just measured my AXSR, AXSA, and ATXC with a pull weight gauge. I hooked it right where the handle meets the black knob on the handle. Here is the average of the results. The ATXC definitely feels smoother, but it is in fact heavier than my AXSA . I assume the XC will get lighter with use. My AXSA has about 800 rounds on it. The AXSR is brand new and the ATXC has about 40.

AXSR-9lb 14oz
AXSA-7lb 6oz
ATXC-8lb 2 oz

Gotcha. You've been waiting since December? And then they said June?
I’ll double check my order date, think I placed it mid October. Initially was quoted “around Christmas”. Then after the 1st of the year I called EO and was told they were expected june. Im sure this wont be the last time I wait for AI products. I was just curious if anyone had more information than what I was given. The order is for a left hand, fde, 6.5 creed atxc, so the left hand bit is probably not helping.

That's rough! Yeah the left hand is unfortunately screwing you even more.

Still heavy as hell it sounds like. I like 90% of the atx/atxc system, the manipulation of the bolt is the bane of my AI enfatuation. I know it's a 60° lift, so in theory that should be 33% more cocking force? How heavy is the fp spring? A weatherby is like 54° lift, similar 9 locking lugs, but requires far less effort to work the bolt. I don't know why it HAS to be that way.

IIRC, part of it has to do with the minimum firing pin energy built into the system to ensure reliable ignition of primers across all environmental windows. Not saying this about you - but commercial shooters seem to forget that a lot of these rifles are designed for MIL/LE, and a slightly 'heavier' bolt lift is inconsequential compared to ensuring consistent ignition.

It's basically been the same action since the AW release in 1990, very minor changes minus the quick change barrel that was AT I believe. Now the AT-XC has what it sounds like, a lightened axsa action? If -40° ignition reliability is what they need, I bet there is a 35# spring in the bolt. I wonder if anyone has ever messed around with swapping the spring out.

It is in fact, still heavy lol. But, like I said I would imagine it’ll loosen up some and the entire stroke and whatnot does feel “smoother” for what that’s worth.

It’s getting 2 25x47 barrels and a 6.5cm here soon. I think Fritz just got the .180 reamer.

Probably decent approximations.

Going by the ultra-precise objective measurement units of "feel", my friends AT-X (don't think it's a C) feels about x3 heavier than my Mausingfield bolt lift.

It's certainly stout, not to my preference. But AIs are built for a wide range of environments where it has to work, versus most other rifles which are designed to work in most environments.

Right. I have buddies all the time grab the bolt and they’re like dude, wtf is wrong with this thing? Why won’t the bolt open? And I gotta explain to them why, and for some reason it’s grown on me and I like it. When I swap between the AI and my Impacts it’s weird. I made the switch earlier this year to a Bix N Andy two stage trigger though, and I have that thing setup so similar to my AI triggers, I love it…
