Product Description

Remember we deliver air rifles & pistols straight to your door!

The Gamo GP-20 CO2 BB pistol is a great introduction to the world of air guns and air pistols.

This pistol features a 20-round removable magazine that takes 4.5mm steel BBs and propels them downrange with a mighty 400 FPS of power, ideal for target shooting, plinking, and teaching the importance of safe firearms handling.

The GP20 is powered by a 12g CO2 capsule that's housed within the grip. The grip has a textured, rubberised finish, which is both comfortable and grippy to ensure you get the best shot.

The pistol also features a front underside weaver rail for mounting lasers or torches.
