ok I finally got my stuff from evike today and I installed the scs and all that and I am going to post here how to do it!
ok so you start out with you gun, a nineball, and a scs.
alright now unscrew the three screws I have shown here and also pull out the magazine well/trigger guard
now pull off the top receiver from the lower receiver
now between the outer barrel and the hop up, (only for KJW M700's I believe) there will be a circular thing with holes in it
what I usually do is get an allen wre4nch to do this part (as shown above) you put the longer end of the allen wrench into one of the holes and you pull torwards yourself if the barrel is faceing left (you would push away if the barrel was fasing right) do this untill you completelly unscrew the outer barrel from this circular thing.
now slide the outer barrel off from the inner barrel
ok. now locate the hopup and there should be this circular nub type thing... you gotta push that out
alright. once you pushed that nub out you can remove the barrel and the hopup from the upper reciever
so now at the end of the hop up, (plastic part going around the barrel) there will be a set screw and you need to unscrew this. (there will also be another set screw on the opposite side to... you also need to unscrew that one)
there is also another set screw on the bottom of the hop up that you need to unscrew ( kinda hard to see...)
now you can pull off the inside part of the hop up
so now unscrew that one little screw
now that should split into two parts
now put your scs into that slot right there. if it is to toght then sand down the sides a LITTLE then try again. if it is to tight again, then sand down a little more. you can always sand more off but you cont put more on...
so now put on your nineball bucking and make sure the seam on the bucking lines up with the grove in the barrel.. as shown
ok now put the two parts together around the nineball bucking. make sure you have you scs in place... and make sure the scs was a little loose and can move... also, use that screw and screw the two parts of this together.
alright. now to make sure that you installed the scs correctly, use something to push down the scs. (I used a thin Allen wrench) (this stimulates the hop up pushing down the scs nub.) if you see a lump form (like what happened in the picture) then you installed the scs and the nineball bucking correctlly. if that doesnt form, then try again...
don't forget to Teflon tape. and now you are done! just put everything back together and watch how more accurately youre gun shoots. to begin with, my gun shot really bad because my bucking was ripped.. lol I didnt find that out until I did this guide haha... but it shoots the bb way more consistent.. it has even shown me that I need a heavier bb... ( at like 150 feet my .32s curve up like .2s haha... )
I hope this guise helped
