All I can help with is the scraping part. That sounds like your missing your front plastic ring that goes inside the reciever that keeps your cylinder in place without wobble or grinding. Take off your outer barrel and look inside the front of the reciever. Should be a white ring.
Horrible 'Rattling' Noise When Shooting (+ Couple Questions).
I've just upgraded my L96 with the following:
PDI Hop Chamber
PDI 6.05x495mm Barrel
Laylax Zero Trigger
Laylax 3 Element Piston
Laylax Spring Guide
Laylax Piston Head (accuracy cup thingy)
Laylax Teflon Cylinder
Laylax Cylinder Head
Laylax 170sp Spring
It's shooting quite hot now though - 590 on .2s, so I need to lose 90 FPS.
590 on .2s = 417 on .4s, both make a horrible rattle noise as I shoot. What could it be? Or is it simply the high velocity?
It used to do it with .2s when I was shooting 500 FPS, but not with .4s (travelling at 360 FPS).
Another problem I'm having is the cylinder scraping on the inside of the outer barrel as I push the bolt forwards. I've lubricated it, but it's not made a difference. The outer barrel is a PDI Fluted one if that helps.
I also, had problem with a Prommy hard rubber. The lip (where BBs enter, that stops it going all the way over the barrel) is really tough and BBs get jammed on it, making it extremely hard to push the bolt forwards, and when I do, the BBs are completely ruined, and now the hop rubber's in pretty bad shape. Any idea on this? It was definitely on right.
And finally, apart from getting a new spring, what's the best way to lower FPS? If cutting the spring, I know one coil at a time, but do I have to sand it down or smooth it off? And which way round does it go, cut end in the piston, or cut end on the spring guide?
Sorry for rambling a bit, but I kinda need this rifle shooting perfectly for two weeks time as I have a weekender and want some nice hits
.
Thanks a lot,
Liam
