Nucleas rifle action

[Big4x42u]

What is everyone's opinion on these? Looks to be fairly well built to me.

From their description: "Three toroidal locking lugs (no lapping required)"

I hate companies who advertise in "buzz words" and have no idea of what the words mean. Look up "Toroidal" in the dictionary.

It's a half round lug instead of a flat surface.

If Mausingfields are your thing, I doubt you would be dissapointed with the Nucleus. I personally would (and did) opt for the new Origin (bighorn) action. A ton of features found on the TL3 and It's cheaper then the Nucleus to boot. This is just my personal preference speaking but there are a couple "features" on the Nucleus that I just can't get past. The bolt stop is one. Having limited options to get rid of the odd shaped bolt knob is another. The Origin is cheaper and has all of the features I want, and none that I don't. If you are after a long action on a budget, I guess the Nucleus may be a good option. If you are going short action and can live without some of the more custom options that Bighorn offers, you are basically getting a TL3 for $750 bucks, minus the stainless steel and DLC option.

The shape of the bottom of the lug does not matter.
The front and back are flat.
I dig the little dingleberry on the lug that slides up into the scope base.

The Mausingfield bolt head has two diametrically opposed locking lugs. The bearing surfaces of the locking lugs are shaped as portions of a torus, and bear against surfaces within the receiver that are shaped as portions of a sphere.

Exactly.

Keeps the lug aligned as you tighten the barrel.
At least that's what I ASSUME they put it there for.

[sigstroker]

That's how they explain it. No need to pin the recoil lug. Unfortunately it sorta makes the rail proprietary. You don't NEED to use theirs, but if you don't you'd probably have to saw off the front piece of the rail and have the dingus sticking up in the air.

I don't see what's wrong with the bolt stop.

It's ugly as hell.

I put a barreled action one on order with the barloc, will be nice to switch between calibers quickly

Is there something that prevents them from machining the rail and receiver as one piece? Or do they do it this way to allow for them to easily fix a modular rail cant as specified by the customer?

Rails come in different flavors, 20, 30, 40 MOA.
