Hey folks,

Not sure if this should go here or in the Gun Doc forum, but whatever.

So I bought a Real Sword SVD used off of another user here in the forum. Gun was in good shape, but, it wasn't working properly. I took it out and fired it a few times, but, shots were dropping off well before 100 feet. I figured there was a compression problem, loss of air somewhere in the system, but, I'm a newbie about gun maintenance, so I didn't know what to look for.

It was suggested that I get a new hop up unit, because they're a common problem, but, I've pulled the gun apart, and I think it's actually missing a piece. I think there should be a spring, that sits around the inner barrel, and presses the hop up back against the piston. This spring is not there, which means that the piston fires, knocks the hop up forward, and there's nothing to push it back. This means there's a huge gap between the piston and the hop that air is escaping through, which would explain my problem.

So, two questions:

1) Am I correct? Should there be a spring here?

2) If so, where can I get one of these springs?

Thanks!
