Hello everyone, I have some qustions for the aeg springs..
 

Hello everyone
I did not play Aeg for long, so I am still a newbie..
I have a ak just for in doors game, it shoots around 300~310 fps. I want to upgread to around 375 fps for outdoor games.. I just need to buy a new spring to change it? Or I need buy something more?? My gearbox is makes by plastic and the gear it makes by metal. (cause The gun was buy with cleap price.)
I looking on the internet who they selling Aeg springs, but they are too many..I fell so confus...
Can somebody able to tell me how many FPS with 100 spring?? 120??
150?? 180??

Thank you for everyone and have nice day.

Your age verified, invest in a nice ak.
Don't upgrade your POS plastic ak

310 fps is just fine for outdoors
If your AK is even compatible with marui parts, just buy an 8$ guarder clear hopup rubber, start using .25g BBs and you'll double your range and accuracy.
But that's the only real upgrade you should do to that AK, unless you have a metal gearbox i HIGHLY recommend not upgrading anything in the mechbox.

first of all what make is your ak, if your gearbox is a plastic gearbox, made by a cheap clearsoft manufacurer i dont think it would be worth upgrading. 310 fps is fine for outdoor games also, all the high end AEGs right now and even majority of cheap aegs are based off the marui design, everything should be marui compatible unless you have some cheap crappy gun made from some unknown manufacturer.

but however i think springs should fit? not sure, anyway m120 is about 320 to 350 fps right now, also having a longer inner barrel and other factors also affect FPS,

Hopefully it's not one of those Tippman AKs, had one of those in my house for a while, I swear it shot ok without any hop up, but you dial in a bit and the BBs start hitting the floor in front of you. Even using 0.12g! Lol

M120 spring depending on make is alot more than 320fps its bordering on 450 FPS

if your looking for 320 to 350 go with an M90. 360-380= M100, 380-410 M110
these are the speeds of modify springs in stock guns. they go towards and sometimes exceed the high end in upgraded guns. madbull, systema, and other brands of springs have different rating systems but generally near the same.

if you meant a 120% spring your closer to the mark.

Probably not worth the effort to even put in a new spring. If the gearbox is plastic it will not be able to hold up to the tension used by a heavier spring.

Tech +1: Save up and get a decent AEG where you are age verified. The one you have now, if it is in working condition, will do you until that time comes.

What you have now will probably last longer if you do not start taking it apart and replacing parts.

The old saying goes, "If it's working... don't %^&# with it!"

Hope this helps....

Don't forget this isn't a high quality gun
prometheus MS110 is 380 on a quality build, but can be as low as 320fps on a poor sealing gun

woops not m120 i meant m100 for 350 it actually depends what springs you use, prometheus m100 springs shoot from about 340 fps, systema springs shoot from 365, they all vary in fps, but yes its in that general area. i did mix up the m120 rating to the percentage rating. cuz i meant 120%, PDI springs use Percentage, they shoot around 330 fps. different companies have different springs that have the m120 spring but have a different fps. m120 and 120% are completely two different ratings. =.= my bad
