I’ve had this gun for about a year now I’ve had zero issues with it no jamming no electrical issues -mods -red eye site -flashlight on the barrel -two batteries The mods I’ve put on the gun are very helpful. The red eyesight has red or green colors and different brightnesses. You can also adjust what the Bullseye looks like, and the flashlight on the barrel has stroke mode or just a solid light. It also has a green laser. This gun is a ton of fun to shoot
