1/12/24 Update: We DO NOT recommend this modification as an optimal hop improvement for the VFC M249- please see
our follow-up video. We'll leave this listing up as an alternative that does not require opening up the hop unit, but we strongly recommend instead modifying a Maple Leaf Wonder (70D) as shown in that video.
This is a simple housing designed to accept a compression spring and be affixed to the nozzle of the VFC M249. This solves the accuracy problem inherent to open-bolt airsoft designs without a delaying mechanism to give the BB time to settle.
Both .stl and .step files are included to make it easy to modify for other springs as needed.
To install:
1. Print this file.
2. Epoxy or superglue the spring over the 'nub' of this housing.
3. Epoxy the housing to the nozzle's guide track, so that the front of it fits flush with the nozzle.
