    So I'm planning on getting a Kwa sr10 from evike and it has great reviews. Im not a fan boy and the only aeg I've had is a JG custom factory upgrade something or other. My question is, should I upgrade? I'd like to be shooting atleast 200 ft. and more if I can get it. I'm guessing I should upgrade the barrel, motor, and maybe the piston but the problem is I have absolutely no experience with upgrades. I can take a gun apart mostly but thats about all. So I'm clueless about what parts to get that won't shred my gun to pieces. My budget for upgrades is about 150$ though I would like to stay well under.
    So a recap of my questions:
    Links to upgrade tutorials
    Upgrade parts(specific) with links to buy
    Max Budget: 150
    Is there a better gun for the money that needs no upgrade?

    Thanks

    Buy good BB.

    I'm not sure you'll get over 200 feet. I can't recommend any upgrade other than a barrel.

    When I upgraded my SR10, I wasn't looking to replace every internal piece. I wanted to push up the fps to @400 fps, extend its range and improve its accuracy. To do that, I replaced the piston head, piston, main spring and motor. I also added a mosfet and switched to lipo batteries to improve the trigger response.

    Generally speaking, I have had good luck with SHS and Guarder parts in KWA AEGs. You definintely want to go with the SHS Blue Full metal rack piston and red ported piston head. http://www.airsoftatlanta.com/SHS-Blue-Carbon-Steel-Piston-TT0035-p/32513.htm and http://www.airsoftatlanta.com/SHS-Red-Aluminum-Piston-Heads-PT0003-p/32731.htm

    If you go with a Guarder SP110 spring, it should get your fps to the 400-415 range. Here is the link: http://www.airsoftatlanta.com/Guarder-S110-Spring-for-Marui-AEG-p/34449.htm

    Personally, I like SRC motors but SHS also makes a good high torque motors as well. http://www.airsoftatlanta.com/SRC-Ultra-Torque-Motor-Long-Type-p/70452.htm and http://www.airsoftatlanta.com/SHS-High-Torque-Motor-Long-dj0005-p/32526.htm. I heard that Lonex makes good motors but I have not tried them yet.

    Pretty much any decent mosfet will work. If you decide to go lipo, check out the Gens Ace batteries at Hobbypartz.com. They have a 20c discharge rate and will fit in the base plate of the KWS crane stock. Here is the link for the 7.4v and 11.1v lipo: http://www.hobbypartz.com/98p-20c-1200-3s1p-3333-short-asoft.html and http://www.hobbypartz.com/98p-20c-1800-2s1p-2222.html.

    One last and very important thing to improve range and accuracy in the SR10. Get a PDI W-Hold Bucking. It should get your range out to beyond 200 ft with great accuracy. If you don't do anything else, get the PDI W-Hold. Link: http://www.airsoftatlanta.com/PDI-VSR-AEG-Hopup-W-Bucking-p/64003.htm

    Anyway, that is what I did with my SR10 and I have been very happy with the result. If you try other parts and they work well, please let me know.

    I'm glad this thread has been made because I have been wanting to do the same thing to my SR10. But I don't know anything about taking guns apart.

    There are several You-Tube videos out there on disassembly and re-assembly of gearboxes. Take a look at some of them. You can also learn a lot about airsmithing by learning from/working with an experienced tech. Also check out the KWA forums. The main thing is to take your time during disassembly and re-assembly and to keep up with the parts, I would also read up on the Stickies on this forum as well.

    If you have the option and you have an experieneced tech that doesn't mind showing you the ropes, I recommend that you go that route. There are some tricks that make working in the gearbox a lot easier. You can also benefit from his/her knowledge and (hopefully) avoid some of the beginner mistakes.

    As a starting point, here is a good animation on how a Version 2 gearbox works. [ame="www.youtube.com/watch?v=qlW11m5d4Uk"]www.youtube.com/watch?v=qlW11m5d4Uk[/ame]

    If your going to open the gearbox, and you've never done it, please, please, please, look it up on YouTube and learn a little about it before you try. If to don't I'm going to have to answer you're next thread entitled "I tried to open my gearbox, and a few things flew out, and I don't know where they go..." I dont want to answer that thread...

    When I first started working on inernals, I used this video on Youtube by maxmaz2: How to: Change the spring in your AEG (Airsoft). I know it is about spring changing, but it gets you into the gearbox, and if you have even a slighly mechanical mind, it's pretty self explanatory from there. He explains how to completely break down your gun, it is the best video I have found.
