Strike Industries

Strike Industries designs AR components with more willingness to depart from the standard pattern than most of the market — angled grips, unusual charging handles, muzzle devices with distinctly non-traditional geometry, and a range of small parts aimed at problems the mil-spec design never addressed.

The strength is that they iterate fast and price well, which makes experimentation affordable. Their Ambush and Cookie Cutter comps and the Viper handguards have real followings. Because the designs deviate from mil-spec, check fitment against your specific upper rather than assuming AR parts interchange — most do, and the interesting ones are exactly where that assumption breaks.
