I finally picked up my can today(yay 10 month wait) - Harvester 338 - Rifle - Accessories
I also neglected to determine how it will be mounted(proper mount), and I am a bit of a loss as to what's the correct item. The host is a savage arms model 110 338.
If it did not come with the mount as part of the package, I would reach out to SilencerCo. to get it right the first time. Bummer the vendor that sold this to you did not go over the mounting needs. Wrong time to realize you don't have the correct mount is on or AFTER the most glorious day of the year "Suppressor Day" (the day you pick it up after waiting) Sure hope the one you need is in stock. Bummer to wait for a non-NFA item just to use your NFA item.
I have a Dead Air Ghost I now own two different pistons for but still have not got the can yet!
Looks like it can use the ASR mount or direct thread adapters. The ASR mount is an industry standard 1.375 x 24tpi , so if you wanted to use another manufacturers QD system like Dead Air KeyMo or Q taper you can.
Get an ASR mount for it (screws into the can. Then put an ASR muzzle brake on your rifle. Mounting the can is as simple as screwing it on and then closing the lock on the mount. (ALWAYS double check that the lock is secure!). If you put the same muzzle break on other rifles you can utilize the can on them also.
