HopUp for MTW | Used

These are pulled from working replicas and may show signs of use, but are in perfectly working condition. 

Current generation includes hopup, wheel, retaining clip, barrel stabilizer, and arm.

Older generation only includes hopup and wheel. This was commonly found on the original gen 1 MTWs. These still work perfectly fine, but are made of a weaker material. These are identified as being shinny, while the current generation is matte.
