Where to get thread adaptor?

[JimM44]

Well I bought the M1S barrel which from everything I read is 1/2-36. I didn't order a different option BIG MISTAKE.

I called Gemtech to get a quick mount for my HVT quess what they don't make one in that thread pattern.

So do you guys know where I can get a thread adpator for the 1/2-36 to 5/8-24 which is the quick detach that comes with my HVT?

Edit: WOW, I got it and I'm impressed check my reply on page 2.

If you don't find a source, I am a machinist and could make you one - already made a custom flashhider for my M1S barrel.....

check with TROS

Thread adapter 1/2-28 to 5/8-24 with 5/8-24 thread protector.

TROS adapters are manufactured from 300 series stainless and are black oxide coated. They are guaranteed to be concentric.

Nice link and I checked their web page BUT they don't make what I need.

The link is for a standard 223 thread to 308, what I need is 9mm to 308.

The M1S barrel has 1/2-36 not 1/2-28, they make them so you can't acidentally put a 223 flashider on it by mistake but it's not 308 which is what the barrel is.

sorry too late at night- shouldn't have been posting I guess - they do carry TROS adapator in 1/2x36 but not to 5/8 - Any good machinest can make one as long as they single point the threads and make sure to make it concentric.

Here's a link to AAC's thread gude spec's

TROS I'm sure can do it but it will take awhile your local shop may be looking for work so quick turnabound.

Since no one seems to be making them - instead of making just one on the manual lathe, think I'll setup one of the CNC's. Anyone else want one? Planning on using one of the live tool machines so I can put some nice wrench-flats on them, should be a sharp looking part- and since I can resolve .0001 on these machines.......should be close enough for gubmint work.....

How much? I have adaptors for other stuff so I might be interested in this one too.

[sharky47]

Let me get some made up, but I was planning on asking two ounces of silver (~30 FRN's).

[GrumpyOlMan]

Sharky, I'm interested in your adapter as well.
Once I have that, I'll start jumping thru the Federal hoops to get a can permit and the hardware... My local guy has a whole box of them!
Even then, I can't actually put the can on my barrel here in WA :-(

You can put it on your gun but you cant shoot with it.

Where do people come up with these laws?

Washington State had a real fear of poaching.
RCW 9.41.250 Section 1.(c).

As per RCW 9A.20.021 Section 2, the punishment for Gross Misdemeanor is as follows: "Every person convicted of a gross misdemeanor defined in Title 9A RCW shall be punished by imprisonment in the county jail for a maximum term fixed by the court of not more than one year, or by a fine in an amount fixed by the court of not more than five thousand dollars, or by both such imprisonment and fine."


When I still lived in Oregon we hadn't been taken over by the liberal Evil Kalifornians who moved up to Portland and Eugene, but we would have shoots up in Albany and Huskies would come down and collect their NFA toys to shoot in the match then they would lock them back up at the dealers in Oregon and drive away to Washington - strange state up there.

In WA many LE Agencies use cans and break the rules.
There has not yet been 1 person convicted of using a legal can
and i dont think most LEO would push the issue because they
use them too.
I would'nt push the issue and go to the public range to use a can
or you could be the first to be in a court room and on the news.

"In WA many LE Agencies use cans and break the rules."

Yup, having a monopoly on violence has it's perks....


Anyway, I am in the middle of setting up a Citizen A-20 lathe to run off some adapters, should be done in a day or two.

[JimM44]

WOW, I'm impressed.

I got the thread adaptor today.

It threads on very easy and has a spot at the back for a wrench to add some torque. I will blue it and then add some of the light lock tight so I can remove it if needed and crank it down later. Or I may use the lock washer haven't decided yet.

Then wait for my can, which I was already doing prior to all of this but now it will FIT. Ye Ha.

[sharky47]

Glad you are satisfied with my work, I did make extra because I know I'm not the only one with this barrel.........price is two ounces of silver, PM for details.

Also, if anyone has any other component that would be helpful and is not available - let me know! If it is something our machines can physically make - I'll give it a shot!

[sharky47]

Oh and by the way, I am going to make a few different versions with varying lengths of 5/8 threads. That way if someone runs across a device that is sensative to thread length, I'll have one that fits. Jim, if the one I sent you is to long for your application - we can just swap it out. Also going to make some with 1/2-28 threads, so you can use your .308 can with 5.56 or .22 or whatever - may not be as effiecient, but it will make that tax stamp more valuable if you can use the can on other guns....

Hmmm......maybe I should make one for the 14mm left-hand thread for all my fellow AK/PSL fans.....

[Fudmottin]

I think most cans in 30 caliber are threaded for a length of 0.625" in 5/8-24.

I don't have a finalized design yet (darn close though) for a can to go on my PPK/S. I'll be putting in a PP barrel because the clearance between the barrel and slide is so small and I don't trust a steel sleeve that thin. The barrel is only 0.480" diameter. So the 1/2-28 is out.

I need to practice threading anyway and I don't think I have two ounces worth of silver in my brazing rods.
