I do clean my barrel and bucking after every game day (using methods from your video:)).  And I've also looked into the rhop (read like all the pages of the rhop thread) so I may look into getting one eventually instead of a TBB I guess.  I could always get one of the rhops that's already cut for the barrel, the zhop I think?

Sorry to resurrect this thread, but when I went to my local airsoft store to buy the suggested spring, the tech there suggested that I buy a non ported cylinder and a ported piston head.  It cost a little more than a spring but he said he'd put those same parts in another persons KM4 an it had that gun shooting at just about 400 w/ 25s.
Just wanted to know if buying those 2 items WILL in fact get me to 400.  The reason I did buy them was because as the tech had told me, it doesn't add any extra stess on the motor, which I like.
Thanks

The Gaurder sp110 is a m120 equvilant thus not creating any more stress than whats on the gun.

KWA's already come with a great piston and great piston head giving you the best airseal possible. From other post (not of my own) I have seen many after market parts of supposedly higher quality give worse or the same results. So instead of dropping $50 or so on new parts spend $15 on a new spring and be done with it.

Another thing i could recommend is getting a Danco #14 O-ring and give a proper stretch demonstrated in the DiY section of the forums. That cost like .50 cents and does wonders for airseal.

Well I already ordered the cylinder and piston head....It was only $30.  I guess I'll have to trust the tech then and after installing the two parts I'll report back, hopefully with a good one, on whether or not it worked... I'm not sure what brand the stuff was but the guy said that it worked wonders on another KM4 he installed them on.

okay i would say if you get a sp 130 your going to be shooting at 500fps lmao thats like getting a m140 i have a matrix m120 and shoot at 410 with .28bb i would recommend getting guarder m120 matrix runs hot basically m120 is like m125 from other brand springs

[MTLheaDerick]

i would go with a sp120 or m130 i wouldnt go higher than that and make sure you reseach the brand i know madbul and ,matrix shoot hotter so if you where going to get one of does brands id go with sp110 or m125 for that brand
