Not sure if it has been asked or not. Will the thread timing be held to a tolerance so prefits can be engraved and line up with the stock or chassis?
Coup De Grâce, New Action from American Rifle Company, $899 WOW!
- Thread starter karagias
- Start date
Id be more worried about there thread timing of the pre fits.
We will be doing complete rifle packages with this action. Its something we would like to offer as soon as possible but it will most likely be after the initial release.
We have not fully lined out our pricing structure but it should be similar to our other actions
Ted explained this to me via email. His answer was more of an explanation on how threads work, and the result of pitch dia tolerances.
Ted is an awesome guy and his willingness to explain his knowledge is amazing to me.
I'll let him explain it in this thread if he wants to, but his answer was a little more complicated than just Yes. There are a few things that affect the timing of the threads, and I'll be the first to admit I learned a few new things just from discussing it with him.
He said sometime in the next 8 weeks you can start placing orders but not much more than that, that i know of
His answer was, it's more complicated than that, and after he explained it, it makes sense.
I talked to Ted one time about my M10 scope rings slipping at spec torque. It wasn't your normal direction of slip. It turned into a quite long conversation and he lost me 3 minutes in with his genius. Safe to say we figured it out.
I love Ted, definitely one of my favorite designer/inventor in the gun community... but we need a double stack 223 aics/aw magazine to go with this action ... and a gen 2 cheek rest for the Xylo ... something with a bit more meat.
Well, AI always teases they had a working 223 conversion 20 years ago, so there must be a mag somewhere. It's like cold fusion, just a decade away haha.
The innovation is amazing but, with gen2 coming out in probably less then a year, I've had a hard time going with anything from ARC. Still want a Mausingfield, I'm a buy once cry once type, just my luck the new and improved M8 Mausingfield will drop a few months after I build off of the M7. Almost happened twice. Personal issues I know.
So buy from companies who don't take customer feedback and keep the same action on the market for decades.
FWIW: My friend just bought a new Nucleus to complement his Gen1. He prefers his Gen1. The presence of a newer edition doesn't necessarily make the "old" version less desirable. But maybe it does if you buy a new action with every barrel and resale value is always a concern. Parts availability is the deciding factor for me.

Interesting. I had a Nuke 1.1 and a 2.0 and I sold the 1.1 to get the Archmedes. The 1.1 just wasn’t as smooth as the 2.0
Can't speak to the ARC but to "improvements" I have a couple of Bighorn TL2s, wouldn't trade them for the "new" TL3s, I've owned a Gen1, Gen2 Vudoo and a RimX. Prefer the Gen1, sold the others. Agree with parts availability. Love my Barnard PL, but parts are an issue.
Tried searching this thread but didn't see it..maybe I missed it.
Will the footprint be the same as the Mausingfield or other ARC actions? If I'm able to order a Coup I'd like to put it in a Foundation stock..so could I order a stock with their Mausingfield inlet or would it require a completely separate inlet?

I tried an Archimedes in a mausingfield inlet foundation, wasn't the best fit, lot of body lines overlapping.
Fluted Bolts
Sorry about my recent absence. I've been busy finalizing design so that we can get these into the wild sooner than later. I'll try to get back here again in the coming days to answer more questions, especially those regarding magazines. But for now, I want to focus on fluted bolts.
How do you guys feel about fluted bolts? Flutes were obviously depicted in the renderings at the start of this thread but I'm liking them less and less. We've prototyped with and without flutes and the flute-less bolts are certainly more tolerant of shooters with poor bolt-cycling form. And remember, even good shooters sometime get a little sloppy with their form so this may apply to them as well.
The reason for that is that bolt flutes have edges that interact with receiver edges adjacent to the bolt bore. This is obviously true for any bolt action. I can run a bolt from muscle memory alone so for me, the interacting edges really don't present a problem. But if I deliberately run the bolt improperly by applying adverse torques and lateral forces, the effects of the edges become noticeable.
That said, flutes are not without benefits. They function as reservoirs for dirt and grime that, if tightly squeezed between bolt and receiver, might adversely affect the bolt cycle. They also reduce the mass of the bolt which is a very good thing for the bolt stop.
Not sure what the right answer is on this one. Tomorrow we'll be making bolts with fewer and shorter flutes positioned to avoid interaction with certain receiver edges. That might be the right balance.
Also, this post should make evident that during development, we scrutinize every detail no matter how subtle its effect may be. So please, if you end up purchasing a Coup De Grâce action from us, be very careful about making alterations to it. We are aware that cool looking features help us sell actions, but sometimes, as in the case of fluted bolts, adding such features may result in diminished performance.

I love the looks of the fluted but I’m performance over looks. If they make the action easier to bind junk them in my opinion.
With that said my Falkor and multiple impacts I have tried all have fluted bolts and you have to really try to get them to bind. No way they bind unless you are trying. Even running the bolt sloppy or some side pressure.
My bighorn I bind if I haven’t run it in a while but then I get the hang of it and it’s good to go too.

My vote would be to remove flutes or, as you are experimenting, greatly reduce them.
I like shallow flues, like a Surgeon.
I honestly could care less about flutes on the bolt. The benefits of them are way overstated, as far as I can tell.
Re flutes: I like them too, looks-wise.
But has anyone ever tried “reverse” flutes? Not sure what to call them. Imagine a corn cob without individual kernels but with the horizontal rows, and twist it. You’d get, I don’t know, spiral horizontal “columns” or rows running down the length of the bolt.
Might provide some dirt resistance while better maintaining off-kilter bolt operation.
My dumb 2¢ brainstorm. Might look dumb, others may have already tried it.

Reliability under imperfect operator and operating conditions take priority for me. As such, I would prefer no flutes @karagias.

@karagias I've had several actions with fluted bolts and I've never had an issue with binding. If you're finding issues with binding there maybe another thing causing it to catch on the flutes. I'd say keep them and figure out why they are catching and correct that.

I talked to the Preferred Barrel folks at the NRL Hunter match last weekend. They will have prefits for this action.
I would like to see a YouTube video testing the “flutes grab dirt and keep said dirt from interfering with cycling” theory.

Ted is it possible to add a radius to back end (safety side) of the bolt bore like a lead in to help cut down on those sharp edges that tend to causing binding?
