I have a 223 criterion that is awesome but decided to go with PVA this time. I wanted a custom chamber with the expertise that goes with it. I am an impatient bastard but at the same time I don’t mind waiting for something better.
I too chose PVA for a 223 prefit over Criterion, which I've owned in the past and been very pleased with. I don't mind waiting for a barrel that has been proven here to shoot well...but x2 on the impatient bastard part!

@RFutch ordered a custom chamber with a short throat.
His is almost up for cutting but the lead from NSS on a custom throated barrel is 16 weeks. The delay in contours arriving for certain things is a very large part of why we're contouring in house and using 1 machine for chambering/threading and 1 machine for cutting contours. That was the only way to get caught up with contours not arriving.
@bohem I have some Criterion Savage prefit barrels, a Savage action, and Barloc with barrel nut. The threads on the Criterion prefits and I have heard a Proof CF prefit do not extend far enough so that I can't headspace the barrel. The Barloc is just barely too thick. A buddy got the Barloc to headspace with the thinner factory recoil lug.

Are your Savage prefits threaded far enough so that they will headspace for a Savage action?
I gotta presume that they will work with the Nucleus, and I am hoping that they are threaded enough for a Savage action.

I am wishing I ordered a John Hancock too... Good work. Thanks.

That's a VERY good question. Unfortunately I don't have a Savage action here to test that with right now but I can tell you our prefits will headspace using the BarLoc and ARC barloc collar on a Nucleus and the Bighorn TL3.

We typically thread 0.1" longer than Criterion however I'm not sure what the engagement length is for a PROOF.

If we need to make something longer for it to work for you though, no sweat. It's 1 variable to change in our program and I'll make it happen.

If you have a Savage I can borrow for a day then I'd be happy to measure it and figure out the answer to it based on varying recoil lug thicknesses.

I'd have to ship it to you. If I shipped it, could I have you get the measurement for future barrels, and also just machine back the face of the action so I can run the Barloc with the barrels I do have? Kinda like an aggressive truing job... I wouldn't think that cutting back the action would make any material difference as far as safety or useability.

I'd have a shorter action, but I can just machine back the recoil lug pocket in the stock. It's an HS Precision with the bedding block, so no biggie.

If that is something you could do and wouldn't be more expense than a Savage action is worth, feel free to PM and I can call or email other info.

I have to believe that there are other guys who will run into a similar issue with what is out there. I am really hoping the thread engagement in the Nucleus and Origin is shorter so I can run my Proof and Criterion prefits with it.

Thanks.

We can certainly measure it and keep the information for future builds.
The other option of cutting back the face is a possibility depending on how much needs to be cut back. It might not be feasible to take it all off the action but a balance might be found between a thinner recoil lug and a trim job on the action.

Of course, it might also just be easier to make a thread relief on the back side of the tenon area on the barrels that you do have so that you can run them with a slight mod and no permanent mods to the action and stock.
There might be a few ways to skin this cat, I'm happy to discuss it with you.

@bohem I've got a question about your shouldered Nucleus pre-fits.

On your website there is an option to have the pre-fit cut for the Barloc. Is it only for the shouldered barrel Barloc?

I've pre-ordered a Nucleus and a Nucleus Barloc. The Nucleus Barloc comes with a Barrel nut instead of a front ring of the shouldered version. Assuming I could get my hands on that ring, could you shoulder pre-fit for the Barloc configured with the collar flanked by a ring on the barrel side and that special Nucleus recoil lug on the receiver side?

Any updates on .223 rock creek TL3 pre fits
The ones that we had blanks to cut are in the midst of having the muzzles cut now. We were short on blanks so we got about a dozen chambered and we're awaiting more blanks from Rock Creek. I have a call with them this afternoon to confirm the count on blanks coming in the next shipment. That shipment should be trucked tomorrow or Monday. It depends where they are in the lapping process.

You can order a shouldered barrel without the BarLoc for the Nucleus. The option to add in a BarLoc cut is an add-on. The Nucleus BL cut involves using the Nucleus-specific recoil lug for the BarLoc.

Thanks, I'm aware that I can order the barrel without the Barloc cut, but I like the idea of being able to change the barrel using only a hex key.

Uh-oh. I bought a Proof Savage prefit and Barlow for my Nucleus...

Word of advice to all the impatient customers.

Do yourself a favor and start following the keto diet.... You will be so busy thinking about French fries, pizza, and pasta, you wont have time to think about your nucleus or JHR.

Ask me how I know.
Buy a spiral cutter and replace pasta with zucchini noodles. Awesome - ask me how I know haha

Before we get too far off the beaten path and turn this thread into recipes and baking, here's the answer to a few questions:

The TL3 is shorter than a Savage.
The Nucleus is shorter than the TL3.
The exact specs I'm not posting. I will simply ignore the question.

Order # for a barrel is only part of the story. Right now I'm going through contours as fast as the TL1 will allow, it's 1234am here and the machine is running while I check on PM's.

@RFutch ordered a 1-off barrel that was coming up on 12 weeks like he was quoted for a custom barrel. If I didn't chamber it when I did then the likelihood of 12 weeks wasn't going to happen. There are a TON of 6.5mm Creedmoor barrels in various flavors and I am stacking the contours up on those while I try to clear out old 223's, old 6mm orders, and the other low quantity barrels so that we can streamline how many 6.5mm Creeds come off the machine. That's the quickest way to having them out the door for everyone. We are doing our best to get barrels out while we have 1 machine chambering and 1 cutting contours.

All that being said, I will try to answer pertinent questions but as someone said before, if I'm sitting on the forum instead of cutting chips take a guess what's going to happen to the lead time...

And I happen to like zuccinni noodles. Sauteed with some garlic, onions and a little bit of red pepper flakes... Goes well with venison meatballs.

Thanks.

In the Nucleus specs, ARC says "The distance from the bolt face to the forward face of the recoil lug is 0.825 +/-0.001 inches."

I just don't know the numbers for a TL3 or Savage but now I know my Nucleus should be more compatible which is good because I bought a Savage take-off barrel for times when I want to shoot surplus 7.62*51.

I'll take spaghetti squash over zuchini.

Anyone know the thickness of the recoil lug on the Nucleus? Will it work with all 700 fpotprint chassies?
Oh, I'm a fan of spaghetti squash too - made some chicken parm w/ it and almond flour.

Has anyone who has received a barloc installed it on an MPA chassis? That's my only concern.

@bohem your updates are very much appreciated! I'm one of the ones who has a hard time dealing with long lead times, but your updates definitely help.

Would love to see a breakdown of batches. I thought I saw somewhere that you were breaking them into 30-day intervals.

I'm also curious how the KRG Bravo lefty conversion process is coming along. I had a feeling being left handed was going to push my order further out, but I'm sure it'll be worth it.

Keep 'em coming!

I'm trying to make a note to provide updates as much as I can. We're working a split shift at the shop to get more spindle time out of 2 guys.

That's the sum of it. The more I sit on a forum writing the less machine work is done.

Those are still in the works, I'm a southpaw and I'm still shooting the RH prototype while we get the RH rifles out the door. The LH conversion is definitely something being worked on but it's not getting the attention that a dedicated person would give it because there is only 1 guy running CAD and programming around here.
