There are cheap springer/airsoft verions out there which can be had for a few dollars.
Just remember the cheaper it is, the less likely it's going to last at actually shooting it.
For just costuming though....should be fine.
Just search 'airsoft shotgun' on eBay and find one that looks the same.
Look for the one called an M58. Not sure if it's the same abroad but the cheap but nice looking airsoft on in the UK has that number for a name, I believe the manufacturer is HFC or Well. Hope this helps
