Our take:  Systema is renowned in the airsoft world for their top-of-the-line craftsmanship on all their manufactured parts and products, and is also attributed with having a world-class R&D process through which all products undergo prior to making it into their product repertoire.  Their AEG springs are no exception.  It's no wonder why more airsoft-enthusiasts choose SYSTEMA as their upgrade part of choice, over the many other brands of upgrade parts available.

Airsoft Megastore stocks SYSTEMA direct from the manufacturer, meaning you will find the LOWEST price on SYSTEMA parts at Airsoft Megastore than from any other retailer, guaranteed!  Pricing on the sticker states:  Y1,680 Yen, or roughly $17.83 US Dollars.  Because we purchase direct, we can offer it to you for BELOW what it would cost you to purchase this same exact spring in Japan, the country of origin!


- Irregular pitch upgrade spring made with oil temper wire
- Works with most-all metal gearbox AEGs with any version gearbox (with the exception of the Marui PSG-1 sniper)
- 350-400+ FPS of power with correct installation and other gearbox parts capable of handling an M120

  Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors.  We are not responsible for any damage that may occur with improper installation.  For best results, please do all upgrades at a certified professional airsoft technician/shop.

"For all previous questions, I use this spring in both of my guns and have been using for a long time now. Springs will fit ANY gun no matter what gearbox version, with the exception of bolt action snipers and cybergun items."

Son of a Gun

"At first, I was worried. Disassembling my mechbox, I realize the 120 spring is inches longer than my stock spring, and more rigid too. It was a near impossible task for ME to install it. So did I take it to a professional and pay good money for them to do it? Nah, I just took it over to the stove, and heated up one end. This allowed me to compress it and shave of some inches. Admittedly this can lower your maximum FPS, but it worked like a charm. Once installed, I shot around 370fps with .20g's. "

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
