BLASPHEMY!
We can switch out the recoil lug to a conical one. (There may be a small upgrade fee) Send an email to [email protected] they will add a note to your order.
The SA Nucleus barrel will fit perfectly on the Archimedes LA.
Contact PVA on your order with them. not a problem on our end.
I’m a bit confused. If we want to run a shoulder Barlock, would we need this setup?
Not necessarily. You can still use the flat face recoil lug withe conical ring, collar, and conical ring (this ring interface with the barrel shoulder). ARC's *.PDF description attached.
So basically you’re eliminating a washer by using the setup on the right instead of using the setup on the left that goes onto a regular flat recoil lug?
Yes it would combine one the conical ring as part of the recoil lug. One less piece and also less tolerance stack up.
and that's where i remember seeing this concept beforeGood job on this design Ted! I hope that there is no infringement issues with Teds design and the design from the Ascalon Rifle. It supposedly has a patent pending. It uses a very similar method:

I did. On their website it says recoil lug timed with rail. If that is accurate ime disappointed.Dude, read the thread
So you read the updates, direct from the source, and still asked the question as if we, who have no affiliation w/ the mfg, would know better?I did. On their website it says recoil lug timed with rail. If that is accurate ime disappointed.

Thanks for your help, you are too kind.So you read the updates, direct from the source, and still asked the question as if we, who have no affiliation w/ the mfg, would know better?
Yes that is why I was questioning this. I was hoping someone may have talked to them and maybe they made a mistake on their website. For me this is not a upgrade. Ime also glad I got my la m5 last year as wellYup, and also the website says its nitrided (instead of DLC) and the rail no longer uses their lug design. Those were three features that justified the $1600 ($300 over similar actions), so I hope this isn't true. If so, glad I got my LA M-5 last year. Sounds like they are trying to integrate/simplify manufacturing across three actions with shared parts.
Here's the listed "improvements" on the website.
Improvements
And:
- $1600
- Short action weight 2.25 pounds, long action weight 2.5 pounds
- 83-degree bolt rotation improves knob to scope clearance and shortens bolt cycle.
- Bolt-lug guide rail improves anti-binding performance.
- Dual cocking-cams and reduced cocking-cam pitch eases bolt lift.
- Bump-free bolt closure improves the feel of the action when closing the bolt.
- New bolt stop design improves durability and functionality.
- Enlarged ejection port improves manual access.
- Heavier striker improves ignition reliability.
- Rem 700 style mag well accepts AICS style mags and supports BDL and Wyatt bottom metal.
- Pin-less interchangeable scope rail secured by five conical-head, Torx-drive screws.
- Pin-less recoil lug is clocked by the scope rail.
- Machining in the hardened condition improves final form.
- Salt-bath nitride finish improves corrosion resistance and reduces friction.
INTERLOCKING SCOPE MOUNT AND CHOOSING THE INCLINATION ANGLE OF THE RAIL (Obsolete, 2019 major upgrade)

Thanks. Now I wish I would have got a short m5 before these “upgrades”. I really like my m5I'll ask Ted at SHOT and report back.
Yes, ARC actions use Savage small shank pre-fit compatible barrel thread.Will these be the same barrel spec as the Mausingfield and Nucleus? Already have a couple of shouldered Nucleus prefits.
If I'm being entirely honest, I think the nitriding is an upgrade over the DLC. I had a Nucleus and have felt a few Mausingfields and the Nucleus was hands down slicker every time. Even Impact Precision, which a lot of guys think is about as good as it gets, uses nitriding over DLC.Yup, and also the website says its nitrided (instead of DLC) and the rail no longer uses their lug design.
Gun Jesus tought me that the Denel anti material rifle also has a pivoting bolt handle:
Sometime after SHOT show when they're not crazy busy they've said they plan to introduce a bolt head replacement program. From the photos of the old vs new bolt heads side by side in another thread it looks like they just adjusted the lead-in cut on the bolt lugs to make it a more gradual transition into locking the action closed compared to the original design.Can anyone tell me about Ted finding the improvement on the closing of the bolt on the nucleus action? Did you just email and was the improvement noticeable?
Yes, ARC actions use Savage small shank pre-fit compatible barrel thread.
The overall/outer dimensions are R700 based, you can squirrel this generic R700 away for reference.I was more concerned with overall dimensions than specifically thread pitch for use with shouldered barrels. Think it has been answered that they are the same spec. Appreciate it though!
I’m sure they won’t lose any sleep because they won’t have to listen to you bitch anymore.One year in to the nuke an pre orders are still not filled, plus they are still trying to get it right..... I'll pass on anything arc from now on
Id like to know as well? Gen2 Bolt heads?Can anyone tell me about Ted finding the improvement on the closing of the bolt on the nucleus action? Did you just email and was the improvement noticeable?
Id like to know as well? Gen2 Bolt heads?
Pretty sure The Fix by Q does it also. The bolt knob pivots reward, they call it pre extraction.and that's where i remember seeing this concept before
None of them are based on a rem 700 footprint,I think this is the key here!Pretty sure The Fix by Q does it also. The bolt knob pivots reward, they call it pre extraction.
Yeah that’s true.None of them are based on a rem 700 footprint,I think this is the key here!
Will tomorrowHas anyone at shot gotten a chance to handle an Archimedes yet?
Has anyone at shot gotten a chance to handle an Archimedes yet?
Yes, super smooth action. Liked it a lot.
I'm going to try and bubble this question back up:
Any info on which triggers exhibit the "a slight bump may be felt depending on the trigger used "vs which do not?
You don't notice it.How does the pivot feel? Is it something that's going to take getting used to or is it pretty irrelevant unless you have a stuck case?
