SACair Forum

What other internals would I need to support this spring?I want my gearbox to be top of the line so if you don't think this spring is a good spring I would like someone to tell me what is.Thanks!

Could you be more specific,which spring,gearbox type,etc?

Sorry about that forgot to paste the link! :lol:

I believe Systema is a good choice. Look there first.

Yea the spring is made by systema.I was asking what other internal parts I should get with this spring because stock internals won't support it.I also asked if this spring was a good choice for a spring.

holy crap what kind of rifle are you building? I running a sp120 and I'm at 420 so i cant use full auto.

lol I want to build a high powered G&G m4 or a m15a4 carbine.Everyone says you can't use full auto when you have such a high Fps is that just because the rifle doesn't allow you to or sacairsoft won't let you in the games?

sacair wont allow it

shit, you wouldn't be allowed to use that thing on SEMI

Yeah. That spring is going to go above 550 fps. That gun wouldn't be allowed on the field, even with full-auto disabled.

Yea I know the fps limits I was just wondering what other internal parts i would need to support the spring because stock gears wouldn't support it.I want a list of the best internals I could get and anything else I would need.I just want this gun for target practice and just to mess around with.

Well, get new gears, bearings, piston, all that shit. Just go buy one of everything and make the brand Systema and you should be ok.

you should look into getting the hayne's CNC gearbox. It will probably be the only gearbox that will withstand that spring rate. Also if you're serious about it Prometheus gearsets are far superior to Systema's in terms of fit and finish. Also Guarder, Prometheus or PDI springs offer better constistency than systema springs.

Just get a PTW 8)

Holy *poop* I might just look into buying it!How long on the average do you think it will last if I take care of it?Is systema seriously that bad?Is it wired to the foregrip or to the stock?

what the fuck is the point of having an airsoft gun that you can't play with? Not to mention the waste of money it would be *cough*

Lol I know I know I owe you! :lol: I just want to have it for target practice and just to say i have a m4 that shoots 550fps.

Thats not a wise investment,might as well buy a real steal rifle if you are just going to do target shooting and go to gun club.Other than that your 550fps M4= a wall hanger.

Maybe but I just want to try it out or atleast think about it.Can someone help me out?

you dont want it for target practice lol you want it to shoot someone who you play with that is being a bitch.

yea maybe that too :lol: But seriously do you have any info that can help me?!?!?!

listen to freq88 he knows his shizzle, i love systema stuff, i would go their or promethius gears. remeber u want to spend a majority of the money on a gear imo why? cause if it fails from the pressure of that massave spring then ya...

Yea I like systema to but I have only had systema gears a few times.I don't want to spend tons of money on internals and have it break after a few times using it!
