I've noticed people pushing flash hiders pretty hard lately, and I can't figure out a good reason why. Hybrid devices such as the BCM comp, WarComp, and to a lesser extent Battle Comp, are superior for a GP rifle, not a flash hider. Here's why: most people don't shoot in the dark, and if they do, its pretty rare. Also, if they do, its even more rare that they're in a contested environment where bad guys would shoot back at them without signature reduction. Any level of recoil reduction will be far more beneficial than flash suppression in the majority of circumstances. Hybrid comps provide some level of recoil reduction without producing an obnoxious fireball and concussion like dedicated brakes. And while they are more blasty to stand next to, they're rarely of significant inconvenience.
