I previously reported that on the new Mossberg 590 SPX. It appears Mossberg also have a “regular” 500 SPX.

The SPX features:

* 18.5″ ported barrel (the holes are in just behind the front sight)
* Picatinny rail
* LPA Ghost sight
* “M16 style” front sight
* Adjustable stock.
* 6 round magazine

This shotgun really seems to be crying out for an 8 round magazine upgrade.

The more expensive 590 SPX has a nine round magazine, bayonet lug and Ontario M9 Bayonet.

R&R Arms has it listed for $494.44 but have none in stock, I am not sure if Mossberg has yet shipped any.

UPDATE: There is also a 930 semi-automatic version of the SPX.

The Mossberg 903 SPX autoloader has the same features as 500 and 590 SPX except it has a 8 round magazine.
