I'd contact Browning because I'm getting mixed answers even on Browning's website. You can contact them at 800-322-4626 or email them at customerservice@browning.com and they'll be able to give a definite answer. Sorry but hope this helps.

Larry, the muzzle brake IS included. Quote from Browning - "A removable, threaded muzzle brake helps tame felt recoil and includes a thread protector for when the muzzle brake is not in use." >>> browning.com/news/press-releases/2018-xbolt-micro-bolt-action-rifle.html .....Other vendors are also saying this comes with a threaded muzzle break. Have a great day!

Larry, the Threaded muzzle brake is not included just a (thread protector). Comes with the rifle. Cheers and stay safe!
