Comp-style setup focus: controlling muzzle rise through redirected gas.

Ported setup focus: gas venting directly from barrel ports for flatter tracking.
Quick RazorMP version: both systems redirect gas to help control muzzle movement, but they do it differently and with different tradeoffs. Here is how I break it down in real-world use.

Usually an added device at the muzzle. It redirects gas to fight muzzle rise. Often more tunable, but it can change overall length and sometimes ammo sensitivity.
Barrel/slide ports vent gas from the barrel itself. It keeps overall length cleaner than many comps, but you are committing to a specific barrel/slide configuration.
