Hi all, just got my hands on a second hand KJW V1 M4.
My first GBB; been using AEG's previously. Damn GBB is so much more fun.

I have a few questions:
1. The fill valve on one of my magazines doesn't have the little o-ring/rubber seal in it anymore. I think it still fills fine but not as properly/easily as my other mag. Is there something I can do?

2. I took my gun apart, cleaned and lubed according to one of the GBB maintenance posts on the forum. Used Super Lube (with PTFE) and it works like a charm. Super sweet and snappy shots. However, I noticed that the piston has some dents/scores on the surface. The piston seal looks to be aftermarket (Falcon - purple) and one side of the seal is slightly squashed. What has happened here? Should I purchase the Cradle X-Piston?

3. Apart from cleaning and lubing the gun as I've done, it's just a matter of adding some silicone oil into the propane adaptor and then filling up my mags correct? No other things need done?

4. Say for instance I decide to not shoot the full 32 rounds in my mag, what should I do to clear out the bullet in the barrel? With the AEG I just take my mag out, fire a couple of shots to clear the barrel then put the gun on Safe.

5. If I were to buy the Cradle XPiston, I'd want to get the Velocity Reducer too. Is it also worthwhile to buy the Polybelt? What about the Loading Nozzle Parts Kit?

Thanks guys!
