Will the Archimedes Long Action barrel threads still be backward compatible with the Nucleus Short Action since it'll now have integrated recoil lug?
I ask because I've already put in orders for two barrels at PVA.
Hopefully i can get the action before the barrels get made so i can ship it to Josh for measurements.
Thanks! Can't wait for the Archimedes, gonna run 300 PRC on it.

I guess I'll say it again, but no one will believe it until Ted says it, but they ALL have 1.0625x20 TPI threads with about a .680" tennon (receiver OR lug face to bolt face minus 10-15 thou clearance), and usually about 0.145" GO gauge exposure off the breech face for them to headspace. Mausingfield, Nucleus, Archimedes, long and short actions all the same.
The barloc adds ~.595" to that for a 1.275" long tennon, and still .145" GO gauge exposure. YMMV, check your action for exact numbers, maybe you want different clearances than I do, but I've run 3 barrels to those specs now and they all interchange between my S/A MF and L/A Nuke no problem.

As of now the Mausingfield and Nuke interface drawings at the barrel tennon are identical and they’re pretty much identical to what ledzep listed.
For me it's less movement of the head and no tilting of the gun required to look in it.
@karagias I'm patiently waiting for my XYLO. I shoot NRA highpower and I love my JAE-700 chassis, but it isn't as good as it could be because I can't adjust it quickly between stages. I believe that, as you have described it, the XYLO will solve that problem.
If you need some pre-release feedback from an east coast highpower shooter let me know, I'd love to cut my wait time shorter, I mean help out the team!!!
Keep up the great work and thanks for all the updates recently.

Ross
highpower with a JAE? and this is the upgrade?
curious why you dont go Tubb T2k/ATR or an Elisio?
I have an Elisio, and Gary makes a great product. I shoot it very well, the ability to offset the stock in standing is very helpful.
But, the heart wants what it wants....and I want a stock that works like a chassis.
The action with rail mounted on top never had clean lines. There's nothing clean about a Pic rail. Granted, the previous rail didn't have the clamp bosses that the new one does, but those disappear under the rings. When you see it in real life, it will look well proportioned. I intentionally drew attention to it with the renderings.

Have an Archimedes on order......wondering if a HS Precision detachable mag will work in this action? Thx
Holy mission creep, what the feck? 
As someone that put money down on the Archimedes, I feel the need to speak up.
This new setup, the threads in the aluminum rail will fail and using the fasteners as quasi shear lugs will contribute to the problem. Is there a Heli-Coil in there?
With the integral recoil lug do you also basically start with enough material to make an action with integrated Pic rail?
I'd rather have an integrated Pic rail or something fully constrained like the original Mausingfield rail interface. If you were to use that mating taper design in two pads on each side of the ejection port you could still make it work with rings or a rail.

I don't want the clamp on rail for my two Archimedes on order. I am happy with the Nucleus style rail on my two Nuclei.
I'm not seeing where the Archimedes rail design has changed. All the rail conversations and images on the previous pages are for the Mausingfield.

Yes, pls keep the Archimedes with the rail and not the dovetail. Although, there was no mention of that for the Archimedes, just the Mausingfield.
I do see where Ted mentions that the Archimedes rail design has not been finalized. This would be due to the change from using the Nucleus recoil lug to an integral lug. So, we shall see.
Any reason you wouldn't want direct mount baked into the action? Having the ability to direct mount or run picatinny rail sound amazing. You can direct mount to eliminate a variable out of the setup if your chasing bench levels of accuracy or if you have limited budget you can use the elevated picatinny to give more budget friendly scopes more usable adjustment range. For prs or elr I can see the picatinny being useful too.(obviously the same can be done with rings but will most likely cost more) I can see this expanding the actions versatility without any real compromise. I see as a win for the budget oriented shooters, the money's no object shooter, bench rest, prs, elr or hunting
Timeline of the actions delivery is the only issue I could see? Maybe I'm missing something but I'm struggling to see the issues...
Just for clarity the Archimedes is going to have a keyed rail similar to the original Mausingfield.

Do we have a rough estimate of when they are going to start shipping the first batch?
Im hoping not. I ordered my lefty on day 1 of preorder. Hopefully they had a run of both going
All configurations are in the first batch
I just got a Triggertech Diamond from the Area 419 Father's Day sale for my long action Archimedes build. I hope I don't have to wait much longer for my action or Xylo chassis.
Now I need to figure out the magazine situation to make .284 Winchester work well.

Congratulations on the Archimedes!
It's not often that something so revolutionary comes along. I saw the Xylo video and the grip, and info sound interesting and I will be following with interest as it develops. The design seems very functional and lightweight but right now is still a little rough on the eye, and integrated ambidextrous QD flushcups on the forend and buttstock would be nice, maybe even an option for a bag rider.
How long you been waiting?
I got mine in less than 3 weeks and I know they recently had them sitting on the shelf.

This month isn't looking much promising either gents, spoke with arc yesterday said they have all action serialized & waiting for anodizing & bolt knobs "shooting for August".
Hilarious! I feel 85% confident there’s a 50% chance of seeing them in August
When I ordered the action, all I cared was getting the action so I could put it together for the GAP Grind in October. I'm truly hoping that still happens
If it’s like my Nucleus last year I got the invoice at the end of August and the action the beginning of September with a sub 200 serial number.
I think we all walked into this knowing May wasn't happening, at least if you had been a around for the nuclei.
I was, my bud was waiting a year & 3 months for his, and was hoping they were more prepared and learned from the
nucleus
They're too busy doing R&D on a new action to make these
