Choosing the right kit
See the list below to ensure you obtain the correct kit for your replica. See also that some replicas require additional components not part of our standard kits. For example, for the A&K Masada, you’ll need to swap your INFERNO’s nozzle for an A&K Masada nozzle, as well as swap out your kit’s 14″ V2 Wire Harness for the shorter V3 12″ Wire Harness.
The MTW is designed to be a modular platform with highly interchangeable parts within the MTW-Spec family, with real steel firearms, and with AEGs when possible. The chart below can help you answer compatibility questions among different components and MTW series.

Uninstallation
Got a FRAC but want to switch back to a traditional grip line? It’s easy to uninstall. But first you’ll need a standard gripline and your choice of sling plate.
Loosen the castle nut with an armorer’s wrench, and then unscrew the buffer tube from the MTW to remove it. If your FRAC was preinstalled on your MTW when you purchased it, your buffer tube may had a small amount of blue Loctite applied to the threads, requiring a little additional force to remove.
Remove the FRAC and FRAC orientation ring and replaced with your sling plate. Reinstall your buffer tube. Do not thread buffer tube in past the front edge of the buffer tube extension or upper will not install. Tighten the barrel nut.
Remove the engine from your MTW and remove the FRAC air line with ¼” wrench. Replace it with your standard grip line and reinstall your engine.
Please refer to the normal installation instructions for your WRAITH X (https://www.youtube.com/watch?v=fI1-UJvgGMc) or WRAITH Legacy product, however, MTW-308 owners will need the additional part below to replace the included hardpoint adapter and mini-airline.
