3D model description

Here's a simple adapter you can use to attach your airsoft M203 GL to your DD rail. It only works with a 12-inch rail since 9-inch does not have any attachment points for M203. In order to attach your M203 to your rifle, you will need 2 adapters. Please, note that it is for airsoft ONLY.

The M4A1 RIS II is designed to accept an M203 grenade launcher
while maintaining a free-float barrel.
1. Remove lower rail assembly by loosening and then removing
four lower rail attachment screws. Place two of the lower rail
attachment screws back into lower rail assembly for safekeeping.
2. Install M203 hanger tabs inside upper rail assembly and
rotate downward.
3. Install M203 grenade launcher by placing engagement collar
around the M4 barrel, ensuring that the alignment roll pin is
in line with the RIS II upper rail assembly alignment slot.
4. Once M203 grenade launcher is seated properly, align M203
hanger tabs with the forward-threaded holes on the M203 and
install two lower rail attachment screws through the tabs into
the M203 and tighten.

Feel free to print it for personal use. Please, note that I do not approve of any commercial use of my models.

Please, let me know if you've run into any kind of a problem with this model.

3D printing settings
