Tokyo Marui Pistol Maintenance

[Mik3F]

Ive picked up a Tokyo Marui Hi Capa from the classifeds

What sort of regular maintenance should I be carrying out on it

This is my first GBB and want it to last as long as possible

Thanks in advance

- clean regularly: wipe down surfaces and remove excess dirt and oil from all the moving part surfaces.

- clean the barrel regularly (I clean the barrel after every game day) using a strip of microfibre cloth and an airsoft barrel cleaner.

- reapply oil to the moving parts. Silicone oil for plastic-plastic or metal-plastic parts. Using something like white lithium or PTFE spray. You only need a tiny amount.

Thanks, is it correct that you should only use Nuprol 1.0 gas or similar or is Green gas (Nurpol 2.0) OK

I have been running Ultrair through my G17 with no issues

Maybe every tenth mag I’ll pop some green in for the silicon content

Green gas should be fine especially this time of year. The only time I'd be careful about it is in the middle of summer when temperatures are high. Using a more powerful gas will cause parts to wear quicker but, unlike the claims some make, it won't explode into a million pieces on the first trigger pull.

I've found a toothbrush is useful for getting dirt and grease out of the little books and crannies

Cheers,

Ill grab some Nuprol 2.0 when I next play, unless I can "borrow" some from my lads

If you are after extracting maximum performance from a pistol, the conventional wisdom is the avoid using gases that contain a silicone lubricant mixed in. Theory being that the lubricant gets blown by the action onto the hop rubber, reducing the hop effect or providing inconsistency. The downside is that the various orings and seals in the magazines and gun itself like some silicone on them to keep them sealing nicely. This explains the Honourable Puceflange's post above where he mentioned the use of UltraAir (a silicone free airsoft gas) with the occasional use of a 'green' gas with added silicon to lubricate the seals.

If your pistol is reserved only for close up engagements, then you aren’t going to notice much of a difference if you were to use a silicon containing gas however - so your choice whether the extra (potential) maintenance hassle is worth it. Personally I run without any silicon mixed into my gas, but that's more me just being tight (I use a plumbers bottles of pure Propane in conjunction with an adapter). I add a few drops of silicone every now and then to the pistols blow back unit, and whenever one of the mags starts leaking (pretty rare to be honest) and tightening the baseplate or valves doesn't do the trick; depending where the leak is, I either remove the base plate and use silicone grease around its big oring/gasket before re-sealing, or work some silicone oil into the internals of the valves. It's all dead easy, and dead quick to do - like 5 mins max...

I hope you plan on giving the gas back after you’ve used it ?

as people have said, green gas in fine. In my experience, the hicapa slides are robust - I’ve been running a DOR with stock slide for several years now on green gas. I just switch to ultrair in the summer.

Of course I wil give it back to them, haha
