Pump-Action Plinker (Toy Launcher)

PUMP-ACTION PLINKER: (TOY LAUNCHER)

This the most functional and fun launcher I have made to date and I am very excited to share it with you all. Requires a couple of springs and a handful of M3 hardware to make functional! Currently shoots about 30 feet but I'm experimenting with different springs because it seems like it has potential for a lot more range and power. STEP files are included for your remixing needs.

Operating Instructions:

1. Pull back the pump until the striker is securely latched.
2. While holding the pump back, insert the magazine and make sure the magazine latch is securely in the corresponding groove on the magazine.
3. Quickly push the pump all the way forward so that it is flush with the back of the front plate.
4. Aim, and pull the trigger to fire.
5. Tilt the barrel upwards to a 30-45 degree angle, and pull the pump back until the striker is latched again. This should eject the shell casing out of the port in front of the trigger guard. If the shell becomes stuck in the barrel, gently shake or tap the sides while keeping the barrel tilted upwards.
6. Once the casing has been ejected, push the pump forward to load the next round.
7. Repeat steps 4, 5 & 6 until the magazine is empty, the lift table in the magazine will prevent the pump from moving to the forward.
8. To remove the magazine, pull the pump to the rear position and press the magazine latch. Pull out the magazine.
