Hello,Merry (late) Christmas!
I received a Echo 1 ASR, as well as a Madbull TBB. After finally figuring out that the Madbull Barrel was not compatible with my stock hop up, I tried to put the stock hopup back together...with little success. Any help would be appreciated! I've attached a picture with all the parts in it.
*Edit*
I now have it firing again, but the FPS are insanely low, the BB drops within 5 feet. What did I do wrong?
*Edit* Mods can delete this if they would like, I got the hop up back together.
