FF III ordered, right mount?

[perrytrails]

I ordered my FF III w/o pic mount and this 336 mount shown in pic. If this isn't gonna work can someone link the right mount for me. Thx

And this is for a 870 youth 20 ga. Thx

No that's not the mount that you want.  What you are looking for is the Burris made Marlin 336 mount that is made specifically for the FastFire sight.  The part number is 410333.

Where do I get this mount?

What other options do I have?

No speed bead mount for 870 20 ga?
