Base for a Mossberg 510

[AndyH]

For those of you that have mounted red dots on your Mossberg 510's what base are you using? I've got a FF3 for my daughters and need a base.

Put  a picatinny base on my daughter's 510. Picked it up from a tactical place here in PA (on the web). I'll try to remember the name.

I used a Weaver base for my son's 510 Mini, I cannot remember the model # though.  I think it was around $8-9
