G36c spring upgrade

[andyj1989]

I just bought a marui g36c and am looking to upgrade the spring with a PDI spring but which spring further more i have no idea how to do this so if anyone knows how to or knows a site where it shows, that would be great.

thanks

Hey, this should help. www.airsoftplayers.com/guides.asp

FYI: there are already topics on this subject, try some searching. And if you had looked about 4-6 topics down you would have seen something on spring upgrades.

Anyway, best o'luck

For a G36c, you should probably get a spring around 120% to 130%.

What spring you get depends on what velocity you want to achieve.

If you want to keep the gun under 350 fps to keep it usable in CQB stick with a 140% or under. If you want to keep it under 400 fps to stay out of that engagement limit, use a 170% or under.

Here's a good chart with PDI and Systema springs and their theoretical fps.

Remember, those are JUST theoretical. I've seen the same springs varry over 30 fps. Also note, that not all of PDI's springs are listed. They do make a 130%, but it's not on the chart. You can estimate what an unlisted spring will shoot at based on the fps of the springs near it.
