Symptom:
- BBs does not appear to feed into the chamber
- I get 1 or 2 actual BB’s shot out with 5 or more trigger pulls on semi
- On auto, it shoots like 1 to 2 real shots with about 10-20 cycles
Current Setup:
VFC VR16 M4 base gun
- Lonex hop up chamber
- Lonex cylinder
- Lonex nozzle
- Modify flat hop bucking
- Modify 16:1 modular gear set
- SHS v2 tappet plate
- M100 spring
I’ve tried different hi/mid caps and got same issue, so can rule out any magazine issue. My suspicions are below but I have not been able to verify them:
1) The nozzle and hop up are not to spec to allow the BB to enter the chamber?
2) The modular gear set is not allowing the tappet plate to move back far enough?
I could be totally wrong but these are all I can think of for now, and will need the experience from the community from here.

Eliminate feeding issues of the mag completely by simply turning the gun upside down.
You might need to adjust nozzle alignment. There's a guide around here somewhere.
Adjust hop up so that there's some hop but not all hop.
Check for compression.
More if I can think of any.
