The Phantom .22 suppressor is designed to be lighter, quieter, easier to maintain, yet affordable. It provides superior sound reduction on both pistols and rifles thanks to a newly designed baffle system. Features a shielded interlocking baffle stack made from heat treated 17-4 stainless steel with indexing tabs for proper orientation. The outer assembly uses 7075-T6 aluminum blast chamber with stainless steel 1/2-28 thread insert and 6061-T6 tube housing. Handles rounds up to 5.7x28mm while weighing only 4 ounces.
