An interesting comparison between a suppressed .308 FAL vs. an Unsuppressed FAL.

The unsuppressed shot comes right at the end of the video.

They were using a AAC Cyclone 7.62MM Suppressor:

The CYCLONE is a thread-mounting silencer for 7.62mm bolt action and semi-automatic rifles. Constructed entirely from welded 300 series stainless steel, the 8.38″ Lg x 1.50″ diameter CYCLONE is the most compact and durable 7.62mm rifle silencer on the market. The computer optimized baffle stack of the CYCLONE delivers a substantial frequency shift, and the resulting muzzle report is indistinguishable from the ballistic crack of the projectile in flight. The weapon’s flash signature is completely eliminated, and recoil is reduced to the extent the shooter can actually see bullet impact through the scope. The slight added weight of the CYCLONE will assist in reducing barrel harmonics which can equate to a significant increase in accuracy with many host-weapons.
