Guarder Oil Temper Wire AEG Spring For Tokyo Marui Style AEG (Power: SP-120)

"The SP-150 spring is FANTASTIC for the AS01/AS02 Strikers! Better than the Irregular pitch springs I've had. Every airsoft website is constantly out of Striker SP-500/550/600 upgrade springs and this is comparable to the SP-500 upgrade. I'm slinging .40g with ease using the Guarder SP-150.

HIGHLY RECOMMEND FOR ARES/ELITE FORCE STRIKER BUILDS

"Hey guys so used this for my new build and it works fantastic!
Here is the parts list, I mostly used guarder for everything except for a few things.
This compression set works great together!
SHS green nozzle
Guarder piston head, sp120 spring, cylinder head, advanced tappet plate, cylinder head
Bolt ported piston

"Very good springs, consistent FPS and they don't become too compressed over time.

"I have bought three of these springs for different builds that I have done lately and the have worked great! The springs are of high quality and work good!

"Bought this for my bolt action matrix SVD. The stock spring ranged around 400. After swapping the spring it ranged about 500-550. Even though its amazing, it won't qualify in California's airsoft field

"Great for dsg builds I get around 330-350 on my dsg
