The “ACE” Chamber System”......Anybody Tried It?

Edsel Ranger, some people loved 'em, others not so much.

Making a perfect chamber with a perfect throat centered on the bore in the throat is pretty much how I do it...I just don't need to do it in 2 pieces....I'd be concerned about how perfect the joint between the chamber and the barrel is, especially if he is mass producing.

I agree, pass on that idea. Pretty easy to chamber up a new barrel. Why mess with all the other BS

Let's do a what if.
What if you built it this way?
1. Chamber section includes a short section of the freebore.
2. Barrel section has the leade, which has no cylinder section, but the staring diameter is larger than the freebore diameter of the chamber. Basically a funnel.

There's a difference between being respectfully skeptical, vs being aggressively opposing.

Besides, what proof could he possibly provide, that would be accepted?

I guess it's too much to ask that people actually have experience with the product they are bashing.

I have no idea if this ACE idea holds water, but I'm not stupid enough to think I'm so smart that I don't need to have tested it first hand, to have my opinion on it be worth anything at all.

Well.....the fellow did certainly 'lead with his chin', didn't he? What the hell does he expect with his untested claims of precision surpassing those obtained by a properly cut/reamed chamber.

Would the chamber section make the gun an SBR if the barrel was not permanently attached to it? No different than having a sub 16" barrel with a muzzle device attached to bring the length up to the legal length. And in that case the muzzle device must be "permanent" to count as part of the barrel.

Good question. barrel extensions to get to the legal 16" length for a rifle have to be pinned and tack welded. Now this will look like a normal rifle so generally nobody is going to question it unless they get a tip. But under legal scrutiny, it would probably be found illegal.

The only way I could imagine it not being illegal is because it does not have rifling. The Franklin Armory Reformation uses a barrel that does not have rifling in a traditional sense. It has straight lands and grooves and because of that the ATF has stated it is not considered a “rifle”. They sell a AR with a barrel under 16” with a stock attached but the ATF has opined it is not a short barrel rifle because the rifling do not spin the projectile.

I know for a fact that mine shoots like crap ! going to take it off order a new barrel and send it to a smith to be chambered. maybe then maybe it will shoot groups.

Didn't Colt do this on their 1911's in order to handle the 22 LR?

Floating chamber​

[edit]
floating chamber
To avoid consuming a lot of relatively expensive rounds, many armies, including the United States Army, trained machine gun crews with less-expensive sub-caliber ammunition in the late 19th century and the first half of the 20th century. To do this, they needed a cheap .22 LR cartridge to operate firearms designed to use the .30-06 cartridge. David Marshall Williams invented a method that involved a separate floating chamber that acted as a gas piston with combustion gas impinging directly on the front of the floating chamber.[13] The .22 caliber Colt Service Ace conversion kit for the .45 caliber M1911 pistol also used Williams' system, which allows a much heavier slide than other conversions operating on the unaugment blowback mechanism and makes training with the converted pistol realistic. A floating chamber provides additional force to operate the heavier slide, providing a felt recoil level similar to that of a full power cartridge.[14]
