NERF FORTNITE - PUMP SG

The Pump SG is a pump-action breech-loaded blaster. It is based on the pump shotgun weapon from Fortnite. The breech is located on the left side of the muzzle. Pulling back the pump unlocks the breech and pushing forward will automatically close the breech.

Despite not advertising it as such and having a very small capacity, The Pump SG can be slam fired.

Official description
Inspired by the equipment used in Fortnite, the Nerf Mega Pump SG blaster captures the look of the one in the popular video game. Fire a big Nerf Mega dart into the battle and dominate the map! It's easy to get ready for action: Open the door on the side of this breech-load blaster, load 1 dart inside, pump the slide backward and forward to prime the blaster, and press the trigger to send the dart flying through the air. It comes with 4 Nerf Mega darts so you can load another dart and keep on battling. Hand-powered by you -- no batteries needed. Eyewear recommended (not included).
