Barrett’s AM338 is a purpose-built titanium suppressor designed to pair with the most demanding long-range platforms. Ideal for .338 Lapua Magnum and compatible with smaller calibers, the AM338 offers exceptional sound suppression, minimal point-of-impact shift, and long-term durability under extreme conditions.
Measuring 9.90 inches in overall length, 1.80 inches in diameter, and weighing approximately 20.8 ounces, the suppressor uses CNC-machined, orbital-welded titanium construction. This ensures strength, light weight, and a perfectly concentric bore for reliable accuracy at long ranges.
It mounts via a 3/4×24 thread pattern and includes a Barrett muzzle brake adapter, providing secure lock-up and rapid installation. Designed to meet military and law enforcement standards, the AM338 is full-auto rated and finished in a matte black protective coating.
