The Barrett AM338 is Barrett’s .338 Lapua Magnum suppressor for MRAD platforms. Barrett — the Tennessee manufacturer behind the M82A1 and the standard by which 50 BMG precision rifles are measured — builds the AM338 for their MRAD .338 Lapua rifle. The AM338 is a direct-thread suppressor engineered to Barrett’s exacting standards for .338 LM chamber pressure. Choosing a factory Barrett suppressor for a Barrett MRAD means the rifle and suppressor were designed together; there is no guesswork about compatibility, threading, or gas dynamics.
