Manufacturer claim
- AMTAC states its suppressors are full-auto rated.
- Suppression: up to 28dB.
- The AMTAC uniBaffle design continues to add velocity while the bullet travels through the suppressor, which AMTAC calls suppressor push and says leads to a higher muzzle velocity and flatter trajectory for long-range shooting. As the bullet passes through the uniBaffle, the air around it loses pressure gradually instead of all at once, which AMTAC says reduces the standard deviation of muzzle velocity by up to 20% and results in tighter groups and a smaller vertical spread on long-range targets.
- The Kaha CQC features an overbarrel baffle system designed to take advantage of the ballistic advantage of this popular round.

- AMTAC Suppressors are made using materials of the highest quality and machined to exacting tolerances in the USA. They are designed to provide reliable service for tens of thousands of rounds, and come with a limited lifetime warranty.
- The KAHA CQC - 300 BLK is an over-barrel suppressor for 300 Blackout rifles.
- AMTAC: a .30 (762) suppressor will provide slightly less noise reduction when used on a .223 than an appropriately sized .223 (556) suppressor will, but it is still a drastic difference compared to an unsuppressed rifle. You will need a 5/8-24 to 1/2-28 thread adapter.
- Over-barrel suppressors have to fit over the rifle barrel and thread securely into place without touching the gas system on semi-auto rifles, so barrel length, barrel diameter and gas system all matter. AMTAC lists the working barrel / gas system combinations for all over-barrel models as 20" barrel with rifle-length gas system, 16" with mid-length, 14" with carbine-length, and 10.5" with pistol-length.
- KAHA CQC: 0.750" barrel diameter and 4" from muzzle brake to gas block.
