Need little help from Mossberg 500 owners

[ezmiraldo]

Hi all!

Which interrupter should I be using in my mossberg 500: "new" or "old" (see pix)?

The old one came with the gun when I purchased it couple of months back. The new one is a new part that I've ordered. They don't look the same -- although pretty close.

Did I get wrong part?

The new one looks like this one on ebay.

Looks like my new one is a wrong part -- it's for 410 gauge. My Mossberg 500 is 12 gauge. That explains it. Thank you, Blindstitch!

Well I try to help. Although I didn't take either of my 500's apart.
