Magazine funnel
The magazine funnel (English jet funnel ) is an accessory for firearms that is attached under the handle and thus enlarges the magazine well in a funnel-shaped manner in order to facilitate the insertion of the magazine . The point is to have a time advantage when changing magazines in competitions where magazines are changed. Depending on the design of the magazine funnel, it changes the grip surface of the weapon and also the center of gravity of the weapon. Mostly it is used in IPSC competitions.
