Coup De Grâce, New Action from American Rifle Company, $899 WOW!

Be careful with that gauge ball it should be part #9528K44 (1 1/4") not the #9528K24 as list in one section. You would figure it out real quick if you ordered the wrong part number and saw it was only 1/2".
I'm not finding that gauge ball, see the small one, any help appreciated. I know it's probably something stupid I'm doing, or not doing.

Just a FYI for you guys looking for mags. Cheapest I've found them, and are back in stock.
I found some here. In stock, fast shipping. I was very impressed with this guys.

Short Action Precision also carries the 223 AICS magazines. An order over $300.00 gets free shipping. My order shipped priority mail overnight. Depending on you state, there may be no sales tax.

 
Barrel Interface Drawing Error

Gratitude goes out to tstevens who brought an error to my attention. The calculation for the ball measurement should be 2.0217 - .2887 x DimA, and not 2.0217 + .2887 x DimA. I carelessly made the dreaded sign error.

This is just another reason why I love the Hide. You guys are on top of it. Thanks again to tstevens.

Revised drawing is attached and it will be up on the website within the hour.

I saw those, and I'm sure they're great guys, but they aren't great enough for me to pay them an extra 18.35 per mag. (That includes the mil discount from Area419)

Ted, I've been casually musing on the tenon print, thanks for sharing it with the world! I was just curious, is it accurate to say that the ball gauge is used because it can serve as a reasonable approximation of a 30-degree cone at typical case head diameters? I also assume you used it because it's a cheap, easily obtained part that provides a solid, repeatable, and tight-tolerance reference surface.

I'm not a machinist (I do have daydreams though), so forgive me if I'm asking silly questions. Thanks!
 
Pretty sure you read it right, and I'm just butting in, but I do think it would be cool to see would see some new ideas for integral action safeties on the 700.
New ideas are cool since good ones grow what is possible. Would a change like your suggesting need a different trigger then? One of the current benifts to the design is the availability of tt, bix, timny ect triggers being widely available ffor builds or as backups.

That’s why you can build off of a different action if there’s different features you need.
True but the aftermarket support for the Model 70 is near non existent compared to the Remington 700. The only three position safety I can think of for the 700 pattern is Defiance.

There is a possibility of designing a trigger to interface with the bolt in a way that locks it on safe but the bolt would have to have a slot milled into it to allow the lock. NULA used to have a trigger that did that and would allow the bolt to be opened on safe by pushing down on the safety to disengage the bolt lock.

To my knowledge they stopped doing it because their clients were primarily sheep hunters and weren’t loading the rifle until they found a ram anyway.

You can buy a $2500 Defiance with 3 position safety.
 
Probably not gonna get it for 899 either.
For the action it really is as simply as cutting a small notch in the bolt body for a bolt lock, it’s the trigger that is the hold up. Back when Ted came out the the M7 I asked about integrating the bolt lock into his actions but it was more a back burner idea for if he developed his own trigger since no option currently exists on the market and one would have to be made.

That being said as much as I like the bolt locks on my Model 70’s I just carry my ARC rifle slung across my chest to avoid the accidental bolt opening. I started that because I had a round ejected when my bolt caught my bag while walking with my Nuke.

Thinking something like the Krag Jorgensen or Mauser. Something to lock out the firing pin and keep the bolt from opening/closing. (Prevent losing rounds if bolt handle get snagged while rucking, etc) Could be integrated with trigger but could also just be separate. I can totally understand not overcomplicating things though so this is all just my imagination running wild. Though, as you just said, ideas are the start of how we get shiny new things.

And just to be clear. This thread is about the CDG, and it is awesome already. But since someone asked about it, it got my brain turning.

Because some people like that the bolt locks on actions like the Winchester Model 70.
You can add a 3 Pos safety to your Rem 700 through aftermarket.

Here’s one:


There are at least two other makers of such a thing.
 
Honestly I hope ARC doesn't abruptly stop production of the Archimedes. Not until they fully support the CDG with AW style mags.
Archimedes are fantastic actions & comparing CDG to the Archimedes for competition the Archimedes wins based on magazines alone unless your using a .473 case size.

I've run ARC mags with the std follower exclusively the past few years with GT's & Creedmoor's on KRG, Manners, & Xylo with ARC actions & Tika. Haven't had a miss feed or a nose dived round yet! With and without an extension. ARC just needs to make their own double stack that works with the AW cut.

I'm all in on the CDG & Ted is awesome for pushing the envelope. Now he just needs to push it with his own mag design.

Decided to go straight 308 win for the CDG build for 2 reasons.
a. I don't have a 308 bolt gun
b. I wanted to just order AW's that would plug and play in the Xylo or JAE. Will run this in some PRS TAC class this year.

Sitting here figuring out how I'm going to get an extension on One of these AW's. It's going to be a PITA. Might as well make it from scratch. I'll post up some pics when done. I really need to finish the retrofit on my little CNC mill while waiting for the action/barrel.

Never used AW's before so my bitches are probably well known to many of you.
AW's are easy to load sure, but beyond that I'm not very impressed. The feed lips are looong & that can't be good for CRF?? It's pretty damn easy to get 1 or a couple rounds to fly out of these. Rounds stick up so if you inadvertently push down on the front of the top round, out she comes. They're also going to need the feed lips tweaked a little so the rounds have full even contact with the lips + round below. That should help to keep them from popping out so easy.

I guess the Steyr double stacks have spoiled me. They don't have any of the above negatives. They allow 3.150" & have a rib inside that's just ahead of the shoulder. The rib keeps rounds from sliding forward & it steers the round towards center as it feeds. The THB's & SSG's are 2 lug with a 6 oclock lug sim. to the CDG.

Steyr Magazines are my most favorite magazine. I just wish there was more support for stocks/chassis for pro hunter magnum actions.

No, the ball doesn’t approximate the cone. The intersection (contact point) between the ball and cone is mathematically determinate for a fixed/known ball diameter and cone angle. That’s what allows an equation to be used to solve for depth.

Being involved in aerospace manufacturing, I deal with tooling balls on an almost daily basis, often with them sitting in conical nests. And much like ARC, we also typically order the tooling balls from McMaster-Carr, although sometimes from Carr-Lane. I think it's a truth in life that if McMaster-Carr doesn't stock something, it doesn't exist. :ROFLMAO:

Got it, thanks. Took me a hot minute to build the geometry in my head with your explanation but it makes sense now, appreciate it.
