Allen Engineering AEM3 OTB 5.56mm Suppressor - Flat Dark Earth (FDE)

Allen Engineering AEM3 OTB 5.56mm Suppressor - Flat Dark Earth (FDE)

Favored by elite SWAT teams, military units, and professional shooters worldwide, the Allen Engineering AEM3 (Ops Inc 15th Model) Suppressor in Flat Dark Earth (FDE) delivers full-sized sound suppression in a compact footprint. Engineered specifically for 5.56 NATO platforms where overall weapon maneuverability is paramount, the AEM3 strikes an exceptional balance of reduced length, manageable weight, and elite signature management. Whether deployed on an 11.5" carbine or a precision duty rifle, this suppressor tames blast and flash while keeping your rifle lean and agile.

Designed for seamless integration with standard AE and Ops Inc B-Mount brakes and collars, the AEM3 adds just 4.9 inches to your barrel length from the muzzle (and only 3.4 inches from the end of the brake), yet rivals the acoustic suppression of significantly larger models. Its over-the-barrel reflex design pulls system mass rearward to maintain natural balance and eliminate muzzle sag. Built in the USA to exacting military specifications, the AEM3 offers absolute confidence, rock-solid thread engagement, and battle-proven durability for hard-use operational environments.
