Suppressor Mounts- Suppressor mount allows you to use your compatible suppressors with the Sidewinder Self Timing Brake system by simply removing your Sidewinder Brake and installing one of these mounts- Mounts are Black Nitrided to prevent galling- Made to meet manufacturers specifications, but these adapters are not associated with their respective manufacturers in any way.- If there is a suppressor you would like to see a mount made for, email sales@area419.com and we will consider them based on demand.- AREA 419 mounts do not use a collar like the muzzle brake.

Since you will be threading the can on in a left hand direction now, if it is not torqued properly into the suppressor, you may unscrew it when attaching to the barrel. No fear though, its impossible to get the two stuck together in this situation due to the opposing thread directions, simply turn it the other way and they will separate, then start over.Gen 2 Mounts come with a wrench
