Well not sure if this is the right place to post....but was thinking if anyone knows where I can get a barrel chambered in that round (or made/cut)....and try to build an ar 10 ...and someone who would be able to help ....please pass on any info or names ...
Not sure if it has been done ...or If possible to do
But anyways I thought I’d give a try at it
Thanks for any help or advice or references to talk to

22 Creedmoor... love mine in a bolt rifle barrel and can be easily set up to fit in an AR10 mag.

PM or email if you want to discuss a barrel for an AR10... just remember that you have to take care of the gas pressure and volume that will come from this set up.

I've thought about it myself in a 7 or 6.5 twist for the new super long .224" bullets from Sierra. It should work, mechanically-speaking. But you will want a long barrel (24" or better) to burn all the powder in that small bore. Also, the pressure curve will be maintained farther out past the gas port. I wonder if it's feasible to make a custom gas tube even longer than the rifle length or if a small enough gas port will cut down the gas enough?

Another option that is catching steam is the 22 Creedmoor. The smaller case capacity might be a positive, depending on the type of shooting you are doing.
 
Is there a reason you want 22 cal?
Hunting restrictions in your area?

Any competent smith should be able to make you a barrel if you or he has a reamer.

Sounds like a barrel burner but a lot of fun.
Have you looked at the 224 Valkyrie? They already have barrels available for them and factory loads are even on shelves. AR-15 receiver sets as well so way more selection for parts.

Personally I'd do a 243 but here we can't hunt with less than 6mm so I'm biased.

Gas tubes are already available in rifle+1", rifle+2" and rifle+3"
They aren't common but they do exist.
 
He, I was looking earlier at the feasibility of getting a 22-250 upper :)

Alex Pro Firearms is the only company I'm aware of that has properly succeeded in producing an AR10 in 22-250. They also have a stupidly expensive magazine designed to properly feed the 22-250 as it doesn't work too well in a normal magazine.

Last time I checked IRG carried the mags. I think it was about $180 USD each. Perhaps one could get a couple of them if they wanted to do a 22-250 barrel for the Stag 10 but I kinda think going with the 22 Creedmoor would be the smartest route.

Some guys have had success south of the border, including with standard AR-10 mags, provided not loaded with too many rounds. It would seems they sourced their upper from Olympic Arms.

I've got two uppers (308 & 6.5CM) projects going on right now, depending how the legal crap show turns out, I'll might get a cheap .22 plinker in the fall, probably a 22-250.

Yes I’m trying to get all the information I need ...see where I can get the parts ..(if available).who I can get to help me out!,and help build it ...and then go to town ...for varmints and say target or plinking!
 
No affordable/standard NR solution in Canada.

Lol, if a couple hundred dollars difference in receiver cost for a custom build is a make or break for you then you might be in the wrong hobby.

Custom barrel alone can cost $1000, last ones I had made for my ACR and an AR were well over $500 each and that was standard popular chamberings the smith already had reamers for.

The positives would be that with an AR-15 parts compatible receiver set you have a lot more selection for parts and the finished rifle will be lighter and more compact.

I only suggested it because it's another option that would get the OP to a similar spot with readily available parts.

If an AR-10 based rifle is the only option the OP wants to look at then as others have said the 22 Creedmoor is the best choice.

OP, If you go through with any of these hotrod 22's and you're going to build a semi auto I would have 2 barrels made at a time. From what I've been reading average barrel life in the 22CM is about 1500 rounds and fast strings of fire will reduce that even more.

What is the intended use for the rifle when complete? You may want to look into something that's not going to eat barrels so fast if it's just for plinking. A 75-80gr 223 can make it accurately to 1000 yards and will have a much longer barrel life.
Cartridges like this are better suited to a bolt action unless you don't care about buying a new barrel every year or two.

Just something to consider.
This thread has sparked some interest for me in a fast 22 semi but after reading more I think I'd be better off swapping out the 14 twist for a tighter twist barrel in my Rem700 22-250.
 
Complete Gun Repair in St. John’s has a 22-250 stag non restricted they did. I had it in my hands last month. I think they wanted around $2500 for it.

Problem is not so much the money, but the sheer availability. The closest solution I can think of is the ATRS MS upper, which has probably a 1 year lead time. WK upper are pretty much proprietary and not available. MacDef upper are a myth. I don't expect the NEA/BCL Badger to be any better. So AR-10 uppers are really the only choice.

Well, I know that ATRS will make you a barrel if you ask them, not sure if they have a 22CM reamer though, you'd have to email them and ask.
A little closer to home you could try Bits of Pieces, they built a nice 12 inch barrel for an ACR I had a couple years ago ht tp://www.bitsofpieces.com/

Good luck
