The discussion of the Alien series of films and the props used in them is the aim, but if it's got Big Bugs and Big Guns, then they are welcome too!

 Post subject: Airsoft 870 to Ithaca Conversion

I had an A&K Airsoft 870 I wasn't doing anything with so I decided to convert it to an Ithaca M37. It's not a perfect conversion but it's definitely good enough for costuming and the gun is still functional for Airsoft.

Modifications include:

1. Filling the 870 ejection port and adding dummy screws to the reciever
2. Removing the 870 trigger guard and installing a 3d-printed Ithaca style one
3. Changing the magazine cap
4. Slightly lengthening the barrel
5. Modifying the forend by shortening it and adding front and rear trim rings

So far it's looking good, hoping for the weather to let up so I can finish painting it.

If you're interesting in trying this yourself, I uploaded the STLs to Cults. Any feedback would be appreciated!
