I have a few bits that I don't need/use. I'm sure there is somebody else who could use them. I have:

A full airsoft pro cylinder upgrade kit for mb01 based rifles. So most l96s/ aps2 systems will take this but pm me first to make sure it will fit your rif. Comes with the piston, m150 spring, spring guide and cylinder head. Brand new in packet- 40 pounds

Secondly I have a fully stock cylinder and trigger unit from a tm vsr. Perfect if you want to use your vsr on cqb sites due to the standard 280fps of tm. -20 pounds 

Thirdly I have a couple of long shaft motors, one being a classic army high tourque motor, the other a stock g&g motor.-15 for both (always good to have a spare )

The plastic bearing spring guide, used g&g gearset and metal m4 front sight (missing small grub screw) will all come free with the other items. You can have one of the three. With one of the other items bought ? Get it touch if you are interested. Thank you!
