Yes, the barrel is threaded 1/2"x28TPI at the muzzle and will accept any 1/2"x28TPI threaded muzzle device including Surefire suppressors or suppressor mounts with that thread pitch.

.223 Wylde chamber is a hybrid rifle chamber designed to allow .22 caliber barrels to safely fire both .223 Remington and 5.56×45mm NATO ammunition. While the cartridge dimensions of both rounds are the same, 5.56 NATO loads produce pressures in excess of the .223 safe spec
Faxon offers a line of barrels that has a milled slot for a fixed gas block. This barrel is not dimpled.
Our AR-15 barrels will work with the Faxon upper as well as any other standard AR-15 upper receiver.
Our barrels do not ship with a gas block or gas tube.
No, the barrels do not come dimpled, but a dimple can be added by a qualified gunsmith.
No, they will not come with a barrel nut because the barrel nut is dependent on the handguard and not the barrel. They will also not include lube for the threads as the only threads on this barrel are the muzzle threads and you should be using anti-seize grease like Aeroshell 33ms for the muzzle and upper receiver threads. You should refer to the installation instructions for the handguard and the muzzle device of your choosing to determine proper installation.
All of the barrels currently listed will use a .750 diameter gas block.
