WE m4 RIS Compatibility

[Ginocide]

Quick and dirty question:

What RIS units will interface well with the WE GBB m4 series? Is it as simple as throwing on echo-1 rails or is it more proprietary? Thanks.

I'm pretty sure its RS spec, so any RS RIS should work.

If you are looking for clones. If they can fit on KWA or G&P I think it should fit on the WE. As far as I'm aware all of those have RS delta rings.

Someone correct me if I'm wrong.

The WE are compatible with RS RIS's.

The WE M4 will take any of the drop in Knights style rail systems. Some of the airsoft ones like an Echo1 may be designed to interface with the TM style barrel nut and will rotate and not lock on a real style setup. Make sure you get one like the CA or G&P that have a real interface that will lock in and clap down to eliminate rotation.

Alternately, a Daniel Defense Omega 7" will drop in and bolt on guaranteed and will look awesome. It's unique system means you don't have to modify it, but you get a true free float with rock-solid mounting. My favorite right there.

Also will fit: SOCOM Gear Daniel Defense Lite rails, most Chinese rail system knockoffs, any real rail system.

Will NOT fit: MadBull Noveske Rail systems. They have an AEG thread barrel nut. You will need the MadBull WA/WE barrel nut which is sold separately.

alternatively you can also buy a RS barrel nut from noveske to fix that problem as well
