KWA G36c Accuracy Upgrades

[ap27]

So after experiencing an outdoor game, I want to look into upgrades to get my 2nd gen KWA G36c shooting a bit more accurately. From some preliminary reading I figure the first available options would be a tightbore and hopup bucking. I'm not looking to go into the mechbox as I hear they are quite sturdy and I haven't had any problems with mine.

So, first question. Is there anything else I can upgrade apart from a tightbore inner barrel and better hopup bucking? I hear those will give me a slight fps boost as well, which would be a nice bonus!

Can I replace the inner barrel with a longer tightbore and cover it with a silencer? I already use a ~120-140mm silencer (i'll measure it later today) on the gun. Would it be okay to extend the inner barrel into the silencer?

As for the tightbore itself, what bore do you suggest? Stock is 6.05 I think. I'd probably go for prometheus or madbull as I hear they're respectable brands.
I believe stock inner barrel is 247mm. I was hoping to get a 363mm tightbore as it would fit well with the added length of the silencer. Would I need to upgrade my cylinder or any other part alongside it?

As always, any advice is appreciated

The upgrade I would recommend you try first is to your BBs. A quality heavier weight BB has much more stability in it's flight path and will travel much straighter. A heavier BB will also be less affected by wind and contact with grass blades and leaves.

^I used .25 Bastards at my last game. I've already decided to try .28s next time. I'd like to get better groupings as well though. Looking for any upgrades that would help there!

I have a KWA G36C 2nd gen and accuracy is very good for a stock gun. If you want to improve accuracy the only thing to do is to replace the inner barrel by an EDGI for KWA KM4 SR7 DEVGRU 6.03mmx273mm. The stock KWA G36C inner barrel is 260mmx6.05mm. A standard inner barrel would fit but KWA requires a specific barrel made for KWA because of the 2G bucking and hop-up slighlty smaller than marui hop-up. EDGI are the only inner barrel made for KWA. Longer inner barrel won't provide better accuracy as it does in RS. If you want to replace the hop-up you will need to replace the nozzle by a standard marui V3. KWA are using a longer nozzle and requires specific hop-up chamber. You won't find a better hop-up and bucking combination than the KWA 2G bucking so I strongly suggest that you keep this stock and only replace the inner barrel. KWA 2G bucking is as good as Firefly bucking or systema+scs. My KWA G36C is shooting at 390-395 FPS and I'm using KSC perfect .25g BB. I never tried .28g BB but it might be interesting to see if there is a difference in accuracy.
