Strike Industries King Comp .223/5.56 (1/2x28)

The Strike Industries King Comp is the budget muzzle device for a California featureless build. California Penal Code 30515 bans a flash suppressor on a featureless rifle but says nothing about a muzzle brake or compensator, and a threaded barrel is likewise permitted, so a device that purely reduces recoil and muzzle rise is fair game. The King Comp's large dual-chamber design and angled gas ports do exactly that, with no flash-hiding prongs or geometry that a flash suppressor would use.

It is steel with a parkerized finish, threads 1/2x28 onto a standard 5.56 barrel, and includes serrated front faces that double as a barricade or barbed-wire tool. At around $46 it undercuts the VG6 Gamma and the SLR Synergy Comp while delivering most of the felt-recoil reduction a flat-shooting 5.56 build needs.

The compliance caveat is the whole point of this guide: a muzzle brake or compensator that is legal on a California featureless rifle is itself a prohibited feature in New York, where Penal Law 265.00 lists muzzle brakes, muzzle compensators, and threaded barrels among the defining features. The King Comp is a California answer, not a New York one. A New York featureless build runs a bare, non-threaded muzzle.
