Mossberg and Maverick 500 12ga bullpup

Mossberg and Maverick 500 12ga bullpup is there really any difference between the two?

I suspect all the people selling the Mossberg versions saying it's better then the Maverick version are full of it.

They look identical....

Anyone know for sure.

Thanks.

IIRC, early Mavericks only had a single action bar on the pump, later versions went to the double one like the Mossberg. The Maverick also uses a crossbolt safety in the TG versus the Mossberg tang safety. Probably not an issue with the bullpup config. And finally, the Mavericks are made from Mexico sourced parts, the Mossbergs are made from USA sourced parts.
