TM No Hop Up=Roll out

[MatthewRyan]

"Otherwise, it's known fact for this to happen with your hop up turned off."

That's what I wanted to know . I thought this was a gun issue

Obviously I would want to shoot it with hop up its just the one thing I noticed with it turned off my first GBB

Not sure got it from anderson and anderson way back in the day. Its a full metal vertec m9 if that makes a difference it was closer to 400 when i first tested it but with the hop all the way on its lower obviously.

Ya i see most of the new ones are like 320ish they say "new version"
