Alpha Black BPS Problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My Alpha Black will not shoot above 200 FPS. Barely 190. 

I've got a new spring, a new velocity screw, I've cleaned this gun several times.

I've run this gun on a full tank, and I've used it with and without a remote coil. I dont know what else to do. When I first got it the thing shot like a sniper rifle, and now I've got to arch every shot. Does anyone have any suggestions? Should I switch to compressed air as opposed to Co2?

Help!

	Have you changed anything on the marker at all?

	No, but I spoke to someone who suggested it.

	It might be my valve. I have to check it out.

	I fixed one where the player screwed the velocity screw in ALL the way. The screw dropped inside the powertube. He thought he'd lost it and inserted a second velocity screw. The first one blocked the passage enough that he was only shooting 160 fps. Could that have happened to yours?
