R.I.S for standard KWA m4a1

what would be a good R.I.S unit for a standard KWA m4? or would i have to buy a new outer barrel also?
links please (from ASGI would be better )
and how do i install it?

unless you would want to put on a Madbull noveske free float system, or a DD free float rail system.

I have allways wanted to get the noveske free float on my KWA KM4 cqb. but that would be double the price.

how do i install it? same as my handguards?

yeah, if the foregrip on you KWA has a delta ring, where you pop them off and see the outer barrel, then this should work

well i mean so do i take the barrel off.. slip on the R.I.S and then put the barrel back in or take off the front sight?

sorry for double post :C but also would i need to buy something to hold the gas tube in place?

Well, For the rails I linked above, you will just pull the handgaurds off, just the same way as if you were going to install the battery. then you place the ris in the slit in the delta ring just the same way, but be carefull, your battery will no longer fit in the handgaurds with ris installed. Therefore, you will need an external battery bag or a peq box.

Now, for the free float system, these systems come with all new "delta rings" i guess you would call them, in witch you may need to remove you outer barrel, and fasten strait to the body of the gun. Unfortunately, This is a process I have forgotten due to the fact that I haven't pulled my entire gun apart for a while now, and this is just something that comes to me while I do it, not something I know for sure.

By the way, nice choice on the KWA, I have the kwa cqb and I never regret it. This is something I would buy though so as that I don't spend 150 dollars on ris, peq, and a new battery if all you want is a vertical grip and a flash light.

im going with the UTG do you know if i need to mod it so i can slip my battery wires out to my PEQ? and will the CA PEQ hold my intelect 9.6 nunchucks?

if all fails for the utg and u need to mod it a drill should work.

Sounds like the UTG rails fit the KWA's wonderfully based on the reviews, And I am positive that the female conector will fit through those stock rails slits just fine. I may consider geting those for my cqb now.

YAY!!! well better order a PEQ in case hehe but thanks for the info guys
really appreciate it ^_^
with these rails and PEQ ill be 50% done with KWA project
also if you pick em up before me lemme know about the battery and the slits ok ?
