MEGA Dart Launcher Spigot - Easy Barrel Insert - v1.2

(Updated) MEGA Dart Launcher Spigot- Easy Barrel Insert - v.1.2

The air restrictor and the dart post has to be removed otherwise the airflow is to low.
(With the Micro2, you can simply use pliers to break out the air restrictor from behind in the plunger tube by twisting it. The dart post then comes out automatically and only 3 small struts remain, which are sufficient as dart stopp)

Attach suitable o-rings to the designated recesses to connect the Mega Dart Launcher airtight to the barrel of the blaster. 
Just push the barrel insert with the O-ring seal into the barrel of the blaster. 
A little sanding of the outside of the MEGA dart spigot improves the FPS.

It should work with nearly all frontloading blasters and aluminium barrels with inner diameter of approx. 13mm.

• Update 21.2.2025:
  Added a flare to the end of the barrel insert to prevent it from being accidentally pushed too far into the barrel.
  

• Update 5.3.2025:
  The outside diameter of the dart pin has been reduced slightly to avoid rupturing the Mega dart when using the launcher with tuned or high performance blasters. The Mega darts now have less friction on the pin and are not held back as much. Please sand the dart post a bit too.
  

• Update 7.10.2026:
  Added a version with shortened barrel insert - to fit perfectly into the single-dart version of the MicroMax2 (by Domochevsky).
