** $15 for the first barrel, and $10 extra for each additional barrel and/or $15 for each additional upper ** Presenting a lightweight MTW outer barrel with a customizable length up to just over 7 inches long (187mm). Provides a snug fit with the stock and Crazy Jet inner barrels, but PDI inner barrels tend to be very tight. Some post-processing may be necessary. Items are made-to-order. *The older-design MTW feed tube may not fit without some sanding at the barrel’s base; therefore, using the MAXX ME Pro hop unit or advanced feed tube is recommended. *Be very cautious when tightening any metal muzzle attachments beyond 50% of the thread's length. The slightest amount of cross threading or over-tightening may cause the threaded portion to snap off. 3D printed barrel attachments/extensions are the best option for circumventing this issue. ** For Airsoft use only, not compatible with real firearms in any way ** ** Listing is only for the 3d printed outer barrel, no other accessories from the pictured model or components from the MTW are included ** Currently available in black or clear PETG. Can offer any other colour upon request, however the lead time will increase by 5 days. Feel free to reach out with any questions!
