The four-prong design disrupts propellant gases to minimize visible signature during low-light shooting, and the 51T taper mount system provides a secure, repeatable interface for fast suppressor attachment when needed.\u003c\/p\u003e\u003cp\u003eMachined from heat-treated steel with a manganese phosphate finish, this flash hider installs on standard 1\/2x28 threaded barrels common to 5.56 NATO and .223 Remington AR-15 rifles.
