Not really new information but I thought I'd post specifics on the CANSOFCOM specific muzzle device & suppressor that is often seen on CSOR, JTF2 & CJIRU CQB length C8's. As far as I can tell this two-piece muzzle device has only ever been seen on CF Special Forces C8's and the sometimes seen 7.62mm AR10 Supper SASS DMR. The combination is designed to allow attachment of the Ops. Inc. 15th Model Suppressor often seen in use by CANSOFCOM members. The two pieces are as follows:

Descriptions:
If the barrel is too short to properly mount the M4 Collar and has at least 1.5" of exposed barrel, this adapter will add the necessary length. This will also fit on long barrels, but will and about 1" of length. This adapter adds extended 1/2x28 threads and requires the AEMB Mount to mount the suppressor. This works with the AEM4, AEM3, and AEM2.

Description:
Designed for 11.5 inch Colt Commando, The 14 1/2" M4 and similar weapons
This model attaches to the weapon via a patented muzzle brake and an adapter that goes over the barrel for silencer alignment. When fired without the suppressor the muzzle brake effectively reduces recoil and muzzle climb while diverting muzzle gasses slightly forward, away from the shooter. The muzzle brake design eliminates upward and downward blast while reducing muzzle flash. The suppressor mounts via threads on the outside of the muzzle brake centering on a fitting that locks over the barrel. On the M4 this fitting stops forward of the M203 cutout allowing the mounting and use of the M203.
