Hi,
Thanks for the extensive reply. Here's some more info.
The gun is fairly new, only shot a couple hundred bbs with it.
1)
Your hop-up is damaged. There is a circular hop up unit on this gbb and it seems to differ from other types I've seen. I completely dissassembled the gun leaving only the hop up unit tied to the inner barrel. when i look through the barrel as i'm adjusting the hop up, even with magnifying glasses, I can't see anything happening that might apply a back spin to the bb. If this is the problem, what after-market unit would you suggest.
2)
Your inner barrel is wobbling. I was aware of that problem and fixed it with electric tape a while ago. Still no improvement.
3)
Your inner barrel needs cleaning. Trust me, I keep this baby clean. That was actually the first thing I did to try to fix the problem.
4)
Your bb's are too light. I've just tried it with TM .25g's, KSC .25g's as well as Airsoft Elite .20g's (which are what I would normaly use) and the problem is the same
I looked at your post with the pictures and there's great info in it. I think the rupper "ring" inside the hop up unit, although not as flawed as yours' could be the cause of the problem. I noticed it seems really uneven.
Thanks a million for your help. please let me know if you have other suggestions
Cheers

1) Your hop-up is damaged. Check the hop-up mechanism (do a forum search if you don't know what it looks like) and see if you can find any inconsistencies in the construction. Actually, I'm about to post a thread in this forum quite similar to yours, with pictures of what I think are a severly flawed hop-up unit from a KSC G19. I will come back to this thread and throw you a link once I get it done, so you can see an example.
Solution: Replace the hop-up unit.
2) Your inner barrel is wobbling. KSC glocks have a problem with inner barrel wobble, where the O-ring is not quite big enough to create a good friction seal with the outer barrel. Look to the following link for more information.
Solution: Here.
3) Your inner barrel needs cleaning. A clean barrel is essential to a good BB trajectory.
Solution: Clean the damn thing. My inner barrel is short enough to clean with a single sheet of rolled-up paper towel. Just twist it through the barrel until it comes out the other side, and pull it all the way through.
4) Your bb's are too light. Wind and/or the simple light-weight quality can cause a bb to deviate radically, even when fired from an extremely accurate gun. This gets even worse when you use low-quality BB's (foreign no-name brands).
Solution: KSC Glocks work well with (and I speak from experience) KSC Perfect 0.25g BB's. 0.3g BB's are even more accurate, but travel too slow for my personal preference.
Any more questions, don't hesitate to ask. |
