The YHM Phantom .22 suppressor offers superior sound reduction for both pistols and rifles, thanks to its redesigned baffle system. A clever design integrates the rear of the blast chamber as the muzzle cap takedown tool, ensuring you always have the necessary tool for disassembly. Inside, a shielded, interlocking baffle stack made from heat-treated 17-4 stainless steel features indexing tabs for optimal performance. The Phantom's two-part outer assembly consists of a 7075-T6 aluminum blast chamber (bearing the serial number) and a 6061-T6 tube housing the baffles. The blast chamber includes a stainless steel ½”-28 thread insert for increased durability. A stylish aluminum muzzle cap completes the package. The combination of lightweight aluminum and robust stainless steel allows the Phantom .22 to handle rounds up to 5.7x28mm while weighing in at only 4 ounces.
