The RAW Slimline model leverages the RAW thread adapters existing 1/2x20 muzzle threads while still allowing the use of your moderator or other muzzle device
The barrel shroud version leverages the existing 1/2x20 muzzle threads and also has a set of integral threads on the front of the mount that are 1/2x20 to accomodate additional muzzle devices since many of the existing threads on current barrels/shrouds are quite short.
From a clearance perspective, you will want approximately 1.3-1.5" from the shoulder of your existing barrel to your tank to allow for sufficient travel of the weight during turning. 1.3" will give you approximately 2 rotations while 1.5 will give you full travel.
The ATS design does NOT use additional separate muzzle thread adapters that can create concentricity and airflow issues. The ATS uses a set screw to secure the tuning weight so there are no risks of accidental movement if you were to grab the tuner or bump it during an event. The ATS sleeves over your barrel shroud approximately .5" so be sure of your barrel to tank clearance before ordering.
