Customers rifle.

I went back out a re-zeroed after switching one S&B in a lower mount for another in a 1.5" mount. This rifle, caliber and suppressor combo continues to impress me and I hope I can do as well when I get off my belly and on to some positional shooting.

Yep. Playdough with 5lbs of locktite. I stripped one also.
I felt it strip and immediately said it’s not worth it. I knew where that road was going to lead.

Idk about anyone else but my bolt lift is ridiculous. A few people on the hide said it was comparable to a Zeus and that’s not even remotely true. I’m 220lbs and can do 15+ pull-ups and deadlift basically a Toyota pickup. The bolt lift is stupid heavy.
 
Don't you hate it when your expectations get crushed by the reality of a thing after hearing all the hype from people online....
Severely. My AXSR has a marginally better bolt feel overall. I figured with the exaggerations and what I experienced with the AXSR that it would be in the same realm. But this ain’t it with the ATX.

Couldn't resist.

When I first got my AT-X the bolt lift was heavy and gritty but after about 1000 cycles of dry firing it has broken in nicely. It is vet comparable to my nucleus if not better
Same, live and dry firing have broken it in and it's now just on the heavy side but not gritty. Also getting used to moving my thumb behind the cocking shroud first before for leverage before lifting helped.
 
Using the thumb as leverage is something I’ve done for 5-6 years now. I assume most people who shoot PRS comps are doing the same regardless of the action. It’s just an efficient way to run the bolt.

Does alright with the 6CM barrel and a random load of 38gn RL16 with 108 ELDM. 6 shots on the first pic and 5 on the second.

Something I learned last week. Ever since owning my AI, I have never thought about lubing the back of the firing pin assembly. I did so because my bolt was significantly heavier on open and especially closed ever since getting it cerakoted. Little did I realize it was because the factory grease had been taken off by degreasing, sand blasting, and cerakoting. I greased it up and it feels better than it ever has. Everywhere that is circled in blue. A little goes a long way if you use the right grease.

Also grease the rear face of the bolt body where it meets the front side of the bolt shroud.

What grease do you recommend?

Must be something wrong with yours

Seriously mines pretty light. Maybe yours needs broke in.
 
What is the lowest mount you can go with a ZCO scope (with out the top bridge)? I am planning on running scope caps. I finally received my DE yesterday and am looking for mounting solutions. I am thinking about trying out ZCO's rings to save weight. I really like the one piece mount from Tier One that I had on my AXSR but want something a bit lighter.

I wouldn’t go lower that 1.35

Hey while its not overly difficult, its also not really obvious how to replace your fixed stock with the Hinge Assembly. I included some quick short instructions on my website where I list the AT-X Hinge Assembly for sale:


Here they are as well (since I just replaced mine):

Below the manual calls for 44.3 inch pound torque settings for #4 (bolts to main chassis), and #5 which is the bolt to the rear chassis. These are basically the same bolt sets you will use for replacing the fixed chassis with the hinge assembly. The AT-X Hinge Assembly comes with (4) M6 hex screws and (1) M5 hex screw. You will need to remove the part below that is between the screws #4 and #5.


AT-X Hinge Assembly Torque Settings


Additionally, you will need to remove the below part as well (between #1 and #2). You will then replace these with the Hinge Assembly.


AT-X Hinge Assembly Torque_Settings_Rear_Chassis-2

edit - of course there are the other parts like the part that keeps the stock in the folded position - those are pretty obvious so I didn't include them...

Glad someone has a brain here
Sometimes it’s that and other times it’s because people don’t want to be attacked over telling the truth. The mob is always on standby. With my ATX on a tripod, I can damn near lift the rifle and one tripod leg off the ground with the uncocked bolt lift. Too many people are lying to theirselves and to form users. It’s not even remotely close to custom action bolt lift in the 60 degree lift category. My old Cadex shadow, somehow, had impressive and lighter bolt lift than most 60 degrees out there. It also didn’t feel like I was fighting a small midget to lock the bolt up. My Zeus action has a lock up assist where it forces the lockup.

The issue with the action is coming from the fire control system. I greased it and the bolt shroud contact point and it made it slightly better.

I will say, it’s hard to notice its flaw when manipulating the bolt under a PRS style COF. The stress of completing the COF masks its flaws. If you manipulate the bolt fast it’s fine. But the lying about it being comparable to a custom action needs to stop. But if someone believes it to be true then it is what it is.

Agreed. It’s the heaviest bolt lift I’ve personally ever felt. Nothing wrong per say with that but it is what it is. This and lack of 12+ round mags will likely keep AI off the PRS podium for a long time. This is also why many advocate for the 90 degree actions in general for PRS because off an unstable position on a bag it disturbs the gun much less, keeping on target, reducing par times. You can say you’re just as fast with an AI but you’re either lying to yourself or haven’t practiced with a custom 90 degree action enough.

I bought an AI due to the reliability reputation. With a carbon barrel I think the ATX makes a great multi use field rifle. Are there better options for hunting? Yes? PRS? Yes. But the AI is a great all around rifle. Shot mine the other day with a 22” bart carbon barrel. I think it measured .1’s. Sure some luck involved, but it flat out shoots.

I’ll be honest, I bought mine (AXSR and ATX) because they look sexy and I had money to burn. I relied upon user feedback to validate my purchases. Now my only issue is the feedback was not truthful. That’s my main issue. As far as I can tell, so long as there’s a good barrel installed and reloading skills to match, they will shoot. My 6CM and 300NM in those rifles does well as far as groups are concerned.
 
I've been saying this for years. It's true when you're rifle weighs 20 lb and you're running the bolt real hard during a course of fire you won't notice it and you can run it pretty fast. But if the discussion is about objective bolt feel then it just doesn't compare. When I lay down behind a rifle bilit on a custom action and trigger tech trigger and I shoot it it just feels like a marriage of precision. Like you're shooting a scalpel. When I lay down behind the AI with the coarse two stage trigger and that bolt lift and the big fat tang area that eliminates a thumb rest it feels like I'm driving a dump truck. People will argue about it on the internet all day long but I would love to have them lay down behind my two rifles and then tell me the AI feels more precision.
Agree. And to reiterate, it’s the user feedback perception that’s my main issue. Although there could be improvements nonetheless
