Nd Internaled Impulse
Psycho Ballistic on/off drop
It works. It centers the gun very very well.
You had to use lock tite.
THE ONLY REASON THIS LEAKS PEOPLE IS CAUSE YOU DONT KNOW HOW AIR WORKS. If you would notice, the screws on both sides of the drop unscrew for a macro line or w/e. This is because of which side you want your line to go now. Now, so the other side of the drop doesnt leak, the side the macro isnt on, you have to use lock tite. Now was that hard? It is user error if it leaks. They did this for the user so the macro can be on each side.
Also, you dont need to turn the on/off all the way, you just need it to hit the pin and let the ari though, that is another reason why your gun may leak. It is logic and common sense, not product error that is wrong with this product.
This product is great and all the problems it has are user error.
