Product Information:
BB's do not blow up in Barrel due to weight. Now jams due to dirty barrels or crappy BB's sure I have it happen on occasion with DSG gun when barrel gets dirty during game play. This spring is great but the most important things to getting high FPS is of course the internals but your piston head, hop up bucking and how well your piston moves versus piston ring seal. Not too tight not too lose. I have at least one of each of Guarders springs and love them all for durability and reliability.

Its Guarder...I needn't say anything else. But I am required to use 30 characters.

Be ready to fix something if you are not spot on with shims, sorbothane, and AOE.

This is an INSANE spring! If you have DMR field limits of 500fps with .25g BB's, you will need to get the SP 140 spring instead. This thing WILL push you well above 500fps! I have the KWA KM16 SR12 and put this spring in it and of course, heavily beefed up the internals. Here's a list of parts I put in the gun to handle this spring:
Super Core Piston, Area 1000 type 0 cylinder, Systema Aluminum Ported Piston Head, Systema Magnum Long motor, Systema Super Torque Up gears. The KWA SR12 already comes super strong with 9mm ball bearing bushings and metal ball bearing spring guide so those didn't need upgrading. Since the SR12 comes stock with a great rate of fire, I recommend getting the Systema Magnum motor to pull this spring and still have good ROF. I'm also using a 9.6v 4200mAh batter.

Off the chart power!

You WILL need extensive upgrade parts to handle this spring!
If you have 500fps field limits, this is not the spriing to get.
You will also need to use very heavy bb's, like .43's, to get good accuracy. This thing is so powerful it blows the .25's all over the place!

Product Information:

If you do not put in the following upgrades you may have to buy a whole new gearbox, or your gearbox will wear out a lot!

what you need for this spring:
1.) systema super torque gear set
2.) src high-torque motor
3.) src reinforced polycarb piston or jbu aluminum piston with reinforced steel teeth
4.) area-1000 aluminum piston head
5.) 7mm+ reinforced gearbox shell
6.) metal air nozzle
7.) heat resistant selector plate
8.) 7mm bushings (or larger) AND SHIMS!
9.) systema non-bore up cylinder

Once getting all this to get the maximum out of this order you should get airsoftgi .25g+ bb's or else the bb;s that you would be using could blow up in the barrel, and they will also not give you the best accuracy under .25 gram because it would be easier for the wind to push it, and then last the bbs that you are using could have seams in them... I really recommend using bb's that are made by the same company that made your gun (if they are) - if not get airsoftgi's bb's...

without all of these things you MAY have to spend a lot more on fixing it then buying the upgrades... also it would be extremely wise to put in metal spring guides, and echo1 grease after every use.
