Pbcop547 Posted January 3, 2019 Share Posted January 3, 2019 Hi guys. There is something bothering me and i want your opinion/advise. I own a g&g cm16 mod 0. When i bought it the gun was hitting 390 fps. I have upgraded piston piston head cylinder nozzle inner barrel(6.02) it has been flat hoped in prowin hop up, m120 spring(m110 included in the gun) and now the gun is hitting 405-407. The great thing is the unbeliaveble accuracy. The thing that bothers me is that i believed with all theese upgrades it would hit at least 420. Am i wrong? All the parts are great quality.. Thanks a lot. Link to comment Share on other sites More sharing options...
Polluxtroy69 Posted January 3, 2019 Share Posted January 3, 2019 Do you mean 290fps not 390fps? Dont worry. Looked it up them figures seem right. Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted January 3, 2019 Supporters Share Posted January 3, 2019 I'm assuming Murcan, they like to run at over 400fps with MEDs and mandatory bang rules. Things I'd try: PTFE tape around the piston head, and to seal the front edge of the hop rubber. Stretch the piston O-ring: Link to comment Share on other sites More sharing options...

I also put a bit of plumbers tape around the bucking /barrel. Link to comment Share on other sites More sharing options...
Pbcop547 Posted January 3, 2019 Author Share Posted January 3, 2019 I am from greece and in big fields our limits are 450 fps. I don know who Murcan is. Maybe the o ring of my piston needs a little streching cause my piston head doesnt really look like leaking air.. Its tight.. Thanks a lot. I will try this and i will inform you about the results. Btw my opinion FLAT HOP yoyr aegs...!! The result is extreamly pleasing...! Link to comment Share on other sites More sharing options...
Supporters Adolf Hamster Posted January 3, 2019 Supporters Share Posted January 3, 2019 murcan=slang term for american (pronounce it with a stereotypical southern accent) assuming you're after range with that kind of setup drop some .3's or heavier bb's in there and enjoy.....

Pbcop547 Posted January 3, 2019 Author Share Posted January 3, 2019 I am looking for the best range and the best accuracy.. One more question.. I own a guarder 6.02 inner barrel 363mm.. And i was thinking of buying a new one 400-420mm.. Would it be even better and which one do you recommend? Link to comment Share on other sites More sharing options...

Pbcop547 Posted January 3, 2019 Author Share Posted January 3, 2019 Now i am using 0.25 and 0.28.. I am only buying the best bbs i can find. Now i am using bls bios. I checked all my seals and they are all fine.. Cant find out why its hitting less than it should. Even that its hitting pretty good.. Maybe in the future i buy a pdi and the correct cylinder. Mine is for barrels from 300-400 mm. Thanks for everything guys. Link to comment Share on other sites More sharing options...

Stretch the piston O-ring: I have a gearbox in bits right now so I thought I'd try this vid tech out and bingo, nice little life hack there! Thanks for the link. Works a treat.
