VFC M249 Feed Adapter for Box Mags and other feed types you need
the Feed Adapter is placed on the bottom instead of the top, making reloads easier and more ergonomic.
Designed around the following Hardware
- Retro Arms M249 Bowden Spring
- M4x16 Counter Sunk Screws
- M4x5
Version for Microswitch is also added in the files as well as a Version that functions with the Stop on Empty [SOE] Feature
for the Microswitch you will need likely M2 screws and for the SOE you will need 1 M3 Grub Screw Length 10-12mm
REV.2 Changes:
The BB being higher in the feed lips. This should allow the BBs to load better into the feed ramps without issue (Current the BB was sitting 1.3mm above the top of feed lips now it should be 1.5 matching OEM)
Length being shortened from 35mm -> 34.5mm meaning it sits bitter in the tray due to any warpage in tray design (Prevents design from any issues with tilting)
the SOE Latch was redesigned for smoother movement and more positive engagement
Countersunk have also been widened, this should allow for countersunk M4 screws to sit either Flush or inset, preventing the adapter from sitting unnecessarily higher
Microswitch and Standard Adapter bodies now share the same top piece.
Geometry Adjusted to prevent unwanted tilting and interaction with the nozzle
