The VR80 Pro Trigger is the most vital upgrade you should consider for your VR80 Semi-auto shotgun. Component triggers have one advantage over drop-in cassette style triggers, the ability to shed dust and dirt and keep running because they don’t have the tight constraints of the housing. The Elf VR80 Pro Trigger utilizes the proprietary ELF PRO LOCK threaded mounting system. The combination of aerospace grade sealed bearings, precision ground threaded bushings, and screws instead of traditional pins provide a rock-solid trigger system. Because pins require some "play" for the hammer and trigger to rotate, there is always a little play in a traditional trigger system. This new threaded system with sealed bearings adds a level of "solid" you need to feel to understand the difference. This is not your average forged steel component trigger - made of wire EDM machined, hardened A2 tool steel, this trigger is not only easy to keep clean, its precise, crisp break and positive reset will take a competition shotgun to the next level. Installation can be done in minutes using the supplied installation screws.
