Asg ashbury 338lm sniper problem

[theagitater]

Hi guys, just got then upgraded a 338lm, put updated bolt with 150 spring and updated trigger system. My problem is when I cock the bolt and the rifle loads a bb, if I point it down just a little bit the bb rolls down the barrel and out the end. What could cause this?

Sounds like, in my opinion, a bad hop unit not keeping the BB static. Could be wrong, don't know much about snipers.

Usually you havent aligned the hop up correctly, if you take it apart and re build it then it should be fine. Also try it with a little bit of hop up on and see if it does the same

If the bb just rolls out the barrel then the hop unit isn't doing its job. Check the rubber for tears and see if it's installed correctly, then check the hop arm and see it's not damaged in any way whatsoever. Applying some hop should stop it, but I'd rebuild just in case.

Thanks for your reply guys, I was unsure due to the fact that during the strip down and upgrade I never touched the hop. But having said that I did have to remove a grub screw that is the hop adjustment and maybe I hadn't put it back right. Since your comments I have adjusted the grub screw and now the bbs don't roll out the end and chrono'd it at around 490fps +/- 10fps. Haven't had the time to have a good look at the hop unit yet.
