I SURPRISED My GIRLFRIEND With The BEST GIFT EVER…
This video details the use and function of a booster (muzzle device) on an AK-104 rifle chambered in 7.62x39mm. The booster is explained as a component that aids in the cycling of the action by redirecting gas pressure, particularly on models prone to cycling issues. While it helps with reliability, it can also contribute to increased felt recoil, and its removal is presented as an option to mitigate this.
