here is a very simple mod for the nerf Secret Strike
all you need is:
electrical tape, duct tape or gafa tape
Nerf Secret Strike
First, we are going to cover the little whole that lets excess air escape.
now you are going to poor water down the barrel of the gun whilst holding it vertically. you then need to pump it about 5-15 times and then shoot it.shake it so most of the water comes out. you can also just submerge it under water and pump it 5 time but when you take it out you must shoot it a few times. this mod increases the air seal and also allows you to pump the gun more than 10 times without the air limiter interfering.
this should all increase the range by maybe 10ft. you will also have to redo the water thing every now and then to get it to stay like that.
Step 3: My Other SS
this is my other secret strike of which i replace the barrel with a pvc tube. it works better than original.
Step 4: End
