KWA M4 hop up help
Hey everyone,
I just bought a brand new KWA M4 and upon shooting it the first time I noticed the gun sometimes has trouble feeding bb's.
Like, when I stop firing, a random bb falls out the end of the barrel and sometimes the gun doesn't even shoot.
I absolutely have no clue whats going on. Do you think its the hop-up? I've read a few reviews on the same gun and most users say the stock hop-up is crap, most owners recommend you immediately replaced it.
What do you think?
All comments appreciated.
