Hello all,
I am looking for information about the rifling of the 40 mm M203 grenade launcher.
The data I need includes:
- Manufacturer.
- No of lands & grooves.
- Twist direction (right/left).
- Min-Max width of lands/grooves.
I know it is not a small firearm, but if you have clearence to one and you can make the measurments. I would be most graitfull.
Lior
