CZ-USA has taken the proven reliability and accuracy of the 550 Magnum and applied it to the needs of law-enforcement. The H.E.T. model is equipped with a Bell & Carlson tactical, Kevlar-reinforced stock with a full-length aluminum bedding block, a 28" barrel, and a SureFire muzzle brake. An oversized bolt handle adds to the perfect ergonomics of the H.E.T. model. CZ 550 embodies aesthetic elegance and ergonomic design with a Mauser style claw extractor, a Square bridge receiver, a hammer-forged barrel, and a single set trigger. The CZ 550 also comes with a positive 2-position safety. All CZ 550's feature a classic square bridge receiver with a 19mm dovetail milled right into the receiver for the mounting of optics.
