Integrated engine retention clip and feed tube assembly. Easier installation and fewer dropped BBs. Comes standard with MTW Milspec, Forged, and Billet series manufactured after October 1, 2021.
*This is a replacement, not an upgrade, for the feed tube assembly that comes standard on all MTW series. It does not fit MTW Billet Series manufactured before Oct 1, 2021 that feature the Cuddles mascot lower engraving, nor will it fit in newer MTWs manufactured after 2023.
Compatibility:
Depending on the year they were manufactured, please use this image of upper receivers to determine which version feed tube your MTW uses and whether or not an engine retention clip is also necessary. Version 3 feed tubes are also available in different lengths for M4, MTW-9 and MTW-308. The MTW Shotgun uses the same length feed tube as the M4.

From left to right, Ver. 1 (standard), Ver. 2 (Advanced, introduced in 2021) and Ver. 3 (Introduced in 2023)
