EXPLORE THE KOA SERIES
Length, Weight, Sound. Designed with your system in mind.
AMTAC’s flagship over-barrel suppressor, the KOA 5.56 is designed around a 16” barrel with a
carbine-length gas system. The shortest version adds only 3.7” to a rifle’s
overall length. The KOA series is available in three variations, KOA CQC,
over-barrel; KOA E, end mount; and KOA S (Sporting) over-barrel.
KOA CQC
The KOA CQC adds only 3.7″ of additional length to your system and is ideal for short platforms. It’s the ideal option for close quarters, allowing for better maneuverability.
KOA E
The KOA E (KOA Endmount) offeres the same direct-thread attachment as the other models and is a great choice when your rifle system doesn’t allow for an over-barrel suppressor.
KOA S
The KOA S (KOA Sport) is an over-barrel option which adds 5.7″ of length to your system. When searching for maximum decibel reduction the KOA S is a great choice.
