Impact vs Archimedes

Archimedes!
 
Got to take my Arch out today!
Received it yesterday and took the Criterion Nuke 2.0 barrel off (the one that came with the ARC rifle) and put it on the Arch using that 12pt wrench, such a good idea.
Went there with my smith who mostly does Tikka and owns an impact but he was so impressed he wanted to get one too.
The bolt stop thing is a bit of a pain but you kinda get used to it and find the sweet spot.

I still really like my Nuke 2.0 and 1.1. I was originally thinking about selling my Nuke 1.1 but then again ... Maybe I'll keep it to do a 6ARC or 22Valk
 
I don't have a impact, so I cannot compare them.

I was going to get an AI AT-X. But decided to pick up a ARC Rifle with the archimedes action instead. Truth be told I really like it over my other rifles. My kid likes it more then my other AI's. I plan on picking up another action to built a 6cm or 6arc for him for this Fall deer season.

I was also going to get a AT-X and for the same money I got 1 Nuke for the wife and 1 Medes for myself. Much better value to be honest.

Mike you ever do a build on a mausingfield or archimedes?
I've built on everything that's pretty much out there and have done lots of RD work on long hair projects for special Alphabet Agencies on some pretty unique gadgets over the past 35 years. As we all know everything forward of the cartridge influence is most vital but one's choice of a custom action is really up to the end user. There are lots out there that are extremely nice, and there are some that are straight junk. I'd say Ted knows his stuff he's a brilliant man and I take my hat off to him I think he makes beautiful STUFF. We met and spoke to one another at the Shot Show many years ago and stay in touch every now and an again. We spoke about a possible collaboration, but it has not yet come to fruition but maybe sometime soon it will ;) I for one would change a few things if I were to work side by side with Ted and I'm sure he'd be all ears. He has a lot of respect for me as he has stated several times throughout our conversations as I do for him let's see what happens...

I'd go Impact. ARC does some cool stuff but people are growing tired with the constant revisions and erratic lead times. Impact is a no frills custom action that's well made and does what you need it too without a bunch of extra features.
Growing tired of, or being made jealous by? I for one know I turn green if someone comes out with an updated, objectively superior revision a couple months after I buy a product (looking at you @TBACRAY). ARC is generally making things better by popular demand and/or engineering/manufacturing improvements as they revise their designs, hard to fault them for that.

As for extra features, each their own, but the Archimedes is also cheaper than the Impact.

No stop !!! You have to do like Surgeon and not improve your product over the last 12 years and just increase the price !!!
What’s happened to the cost of materials over the last 12 years? Cost of doing business? Cost of keeping a shop opened and the machines running?

The Surgeon 591 cost more when it was released in the mid 2000’s than the archimedes costs today, and the arch has way more parts and processes to make it. The surgeon was always overpriced.
 
The surgeon (which is the predessor to the impact) Was the best action you could buy at the time.

Time will tell but all the extra parts on the ARC actions along with the issues from their previous generations vs Impacts that just plain run.
 
I bought an Archimedes action as my first custom action. As a toolmaker I'm amazed at the quality of work that goes into it.
It is smooth and if you match the cocking piece to the trigger it closes as smooth as it opens. I'm waiting on the sale to get my second one...
No marketing BS just pure performance.

Call Ted and ask him to hook you up before the sale he's a class and might just do that, it can't hurt right?

If my understanding is correct ARC is no longer going to manufacture the Archimedes. What are the chances ARC might put them on sale to dump some inventory and pay for those new turning centers? Kinda hard to want to pay $1099 for the Archimedes while the Coup is at $899.
 
Everything breaks, if it doesn't your sample size it too small.

But I haven't seen anything that would indicate that ARC makes inferior actions. They have certain features that make them unique, but then your getting into subjective again.

Impact is the only action Ive seen first hand go down at a match in my squads. Broken firing pins and trigger hangers falling off.

Not saying its not a good action. Just that everything is fallible and both the impact and the Archimedes are great actions.

Everything fails.

I've seen a chunk of AI's fail at matches (don't tell the AI fan club I said this or I'll be labeled a heretic).

If ARC is failing at a higher rate than other actions, I would certainly be curious to hear it. My only personal experience with ARC actions has been Mausingfields, and they've been nothing but impressive in shit conditions. However, there are very few Mausingfields currently being used in matches. I would imagine when people reference ARC failures they are seeing Nucleus and/or Archimedes, as they represent the biggest % of ARC actions in use at PRS type stuff. I have little to no experience with those specific actions, so I'll reserve comment/judgement.

Observational evidence is not very reliable when you try to scale it up to population levels. If we were to trust observational evidence, that would mean by your observational analysis Impact has a high failure rate, by my analysis AI's have a high failure rate, and by @DeathBeforeDismount's analysis its ARC.

The good news is that pretty much all the stuff being made today is great quality. They all have their own nuances and potential failure points. They can all fail given the right set of conditions and factors. But failures are much more rare in our rifles and their components then they once were.

My personal failure rate for AI is 67% for needing to be sent back. 2 out of 3. Not that that would scale at all, but it is what it is. I also wouldn't bash AI as I'm pretty sure I'm the exception not the rule.
 
Interesting you bring up AI. They one of the least reliable PRS actions/rifles I have seen so far. Same with curtis and stiller, then Arc.

Anything can fail but its patterns that matter. My buddy broke his bolt handle off a defiance deviant at a match, but its rare to see defiances go down to I just chalk that up randomness. I have seen one impact go down, and that was Brady Lamm's trying to run a 22GT blowing pins. Other than that, they just run all day in the worst sand and rain and mudd. Have seen a few nukes go down over the years, have owned one and not impressed with it. Too many small parts. Its an engineers actions, not a shooters. Its a constant evolution, he wouldnt keep trying to make it better if it was already perfect. Feel free to jump on that train but 3 ARC actions later, we will still be running impacts along with most PRS shooters.

My reccomendation for someone buying a new action today. Impact, Lone Peak or Terminus (All the good curtis with none of the bad). Plenty of inlets in foundations and manners, good selection of prefits, very little issue with trigger timing and they just seem to run with little issue.

Impacts and Lone Peak's are solid. They handle shit conditions extremely well. Never had my hands on the Terminus, but like everything I've heard. These are the obvious choices if looking for push feed actions.

Still love my Mausingfield as well - it's a robust design. No real opinion on the Nucleus. Zermatt's/Bighorns seem to do well as well, but they don't seem as popular as they once were.

If i was building a dangerous game rifle, it would be built on a mausingfield, but only by someone like LRI who knows how to do the tuning and get it setup correctly. I have a soft spot for CRF actions , especialy pre-64 Model 70s. I just dont think its necessary and its too complicated for a PRS/race gun.

I am headed across the state to pick up a terminus later today, Excited to run some rounds through it.

Any engineer or designer will tell you that there is no such thing as a perfect design. Everything is a compromise between constraints. I for one appreciate the constant improvements that ARC puts out. It tells me that there is an effort to improve the product and it's nice that the customer knows. A lot of designs have revisions after initial release but it's not always public knowledge.

But I'm also an engineer so maybe you're right it's an "engineer's action".

I gotta ask.

Did your buddy break the knob off the end of the handle?
If not, what the heck or rather where the heck did he break it?

The Deviants and as far as I know, all the Defiance actions including the older Rebels used one piece bolts.

I've personally seen impacts go down and it's usually firing pins. Just out of curiosity what happened to the nukes you've seen go down?

Actually now that I think, it may not be a deviant. Its one of the older ones with the swept bolt handle like an AI.

Maybe that explains why Defiance doesn't do the swept handles anymore 🤔
 
I'm not trying to pick a fight but if the ARCH was such a great action why did Ted stop production on them?
An action can be great but that doesn't mean you have to stop development within your product lines.

If the Camry is such a good car why does Toyota continue to develop it? Why would it reengineer the platform or even new platforms?

At least one reason was that people complained about the rolling bolt release. It was, I won't say more difficult but it was different then what people were use to. He said he was working on a upgraded version a while back, I'm guess it was what the CDG ended up as. Also went with a full thickness bolt to not have as much play, again some called that play sloppiness.

So all in all it's a evolution. And the integral picatinny rail.

I've never seen a Defiance with an AI style bolt handle. Are you talking about the 700 style swept ones because they are one piece also. They are thicker than the newer style too.
