Wolverine Airsoft MTW Castle Nut
The Wolverine Airsoft MTW Castle Nut is the OEM castle nut for the Wolverine MTW HPA platform. The castle nut secures the buffer tube to the lower receiver on AR15-format platforms — the “castle” name refers to the notched outer profile used for spanner wrench engagement during installation and removal. On the MTW, the castle nut uses Wolverine’s specific thread and dimension specification for the MTW lower receiver — standard AR15 castle nuts are not necessarily compatible. A properly torqued castle nut prevents the buffer tube from rotating or loosening under field use and recoil.
OEM Wolverine replacement for MTW buffer tube installation. For MTW operators installing a new buffer tube, replacing a damaged castle nut, or building a new MTW lower receiver, this is the correct OEM specification castle nut for the MTW platform.
