CANSOF IUR Clone thread

[FoxAlpha]

They made the adapters for the 10 inch barrel if I’m not mistaken, however I’ve got the 11.6 barrel and I’m trying to find the actual Allen Engineering M4 collar

The actual AE collars are a ##### to acquire. I spoke with Ron Allen and getting his stuff is cost prohibitive as you’ve got to file the 500 dollar application with the state department and that’s not even a guarantee you’ll be approved. I know Mister Donut here (although I believe he’s been pinked) has one of the proper collars you’d need and he’s the guy that hooked me up with the extended so ATRS and I could reverse engineer a suitable piece for the 10” barrels.

Shoot me a PM and I’ll see if I can dig up his personal email, I doubt he’ll sell you one but he was happy to provide me one to have it cloned by ATRS.


One of these days I should really update the OP with the proper info that has come to light since I started this thread.

I really really hope so, been hearing that for about a year. No offence to him of course, Nordic has been great.

They are sitting on his desk. He just hasn't had time to figure out a price and list them on the website.

He got a permanent ban.

If you really wanted I think this would work as it's for the O.I 12th/AEM5 suppressor, you would just have to use the collar;

Then you could get the airsoft 12th can like mr. donut has, i think it would work.

He got a permanent ban.

What did he get banned for?

I do have the correct Smith Vortex threaded flash hider, and if I recall, the 12th model suppressor isn’t the right one. Although I don’t know if CANSOF uses the AEM4 or AEM5

I believe they use the equivalent to the AEM3. The AEM4 and AEM5 seem to long for the pics I've seen.

Is there a collar available that would work on the 15.7 barrel? Are there training suppressors available that will fit the vortex? This seems like a fun project

The SA 15.7 barrel already has the collar. Its combined with the simon sleeve, if you look at the shoulder after the A2 flash hider , you will see it has the proper angle. (Older CF simon sleeves do no have this)
Nordic has the proper threaded vortex to accompany this for the proper setup of the AEM3/15.7 combo.

 

[Leviathan024]

Interesting. My iur15.7 barrel does not have the simon sleeve

 

[Fuzzy Wool Hat]

that's because the IUR was intended to be used with the H&K grenade launcher which mounts to the rail.

 

[Leviathan024]

Right. So with no simon sleeve what allen engineering collar would i need?

 

[Fuzzy Wool Hat]

I believe the Allen M4 adapter collar is the correct one for the AEM3 suppressor, but you might need to reprofile your barrel to accept it. The collar needs an outside barrel diameter of like .620 to slide over.

The SAS use the surefire suppressor which mounts directly to the FH556-216a muzzle device (someone please sell me one) so I guess they figured they’d just beef up the barrel profile.

 

[Leviathan024]

Thanks. I am learning a lot about suppressors thanks to this thread and had no idea there were so many diffrent mounting options

Got some time in with the CSOR upper. Finished out the upper with a 11.5" BCM barrel and had a local Machinist make the AE sleeve. The barrel wrench from Nordic Marksman is the ticket - very well built tool, kudos to the shop that built them.

Would your machinist be interested in making another sleeve? I seem to have missed the boat.

I sure can, it cost $125 and i need your barrel dimensions. I had them build it so that i would not need a set screw. It is held in place by the shoulder and the FH .PM me

 

[Leviathan024]

Interesting. I may be interested in one for my 15.7 iur and in GP! Did it affect accuracy like some of the others posts claim with thiers?

No this does not affect accuracy. I originally had one built by ATRS as an extension for my CC 9.9" barrel and i did notice that accuracy with the barrel/adapter/FH did not give group sizes that i was happy with (6"-8").

This is a sleeve that goes over the barrel end, so no bullets pass through it like the extension. Understand, the adapter from ATRS was Top Notch workmanship, but the combination of the adapter and my barrel simply did not provide acceptable accuracy which could be a number of things and not the adapter itself.

With the 11.5" BCM barrel, collar, Smith Enterprises FH, i obtain about 1.5" - 2" groups at 50m which is acceptable to me (using the same ammunition).
