Mossberg 500 SPX
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.
In general, I like the way they have this set up.
I’ve essentially built the same thing (hopefully my pic will show up). It is what I’ll reach for to defend the home.

Just a follow on…if the image doesn’t appear, go to the tinypic link to see my shotgun.
What I like on the Mossy is the receiver rail/rear ghost ring set up. I’d like the option to mount an optic on mine. I have a receiver rail for the mossy but it uses the same screw holes as my current sight, so they can’t be used together.
Why oh why do they put the front post sight of an AR-15 on a shotgun? Reminds me of those FN shotguns, and I just loath it. I know the shotgun in and of itself is pretty solid, but they do not require a front post sight. I also loath putting a M4 butt stock on anything other then an M4. To Mall Ninja for me, but I do like the idea of rails. I just do not see them in the right spot to put a weapon light on the shotgun.
Coupla reasons for the collapsible stock…
1) it is the stock on the Knoxx stock…and that system is awesome. Bye-bye recoil
2) allows for multiple clothing options…e.g., t-shirts to body armor
3) allows multiple shooters with the same gun…e.g., me, wife, son
Kris,
I’m looking for the SPX 500 but no one seems to have this phantom rifle in stock. I personally like the M4 sights and collapsible stock if for nothing else but total badashisness. Was hoping that you could provide more details on your setup as I would like to build one of my own. More info such as brand names of the sights, saddle, etc would be much appreciated.
I bought one just the other day. The sights aren’t bad. The front site has a red transparent rod, in good light it glows. I haven’t fired it yet but it is very easy to keep the dot in the center of the rear sight and track with it.
I’ve bought an older Moss 600at for 75 bucks last week. I’ve ordered an ATI collapsible (M4 style) stock with pistol grip for it. I have the barrel at a gunsmith to cut it to 20″ and recrowned.
I like the M4 style stock on it. I like being able to store it collapsed and then expanding it to where I want.
Now, where can I find an elongated magazine tube for this?
The main reason for a collapsible (M4 style) stock is for effectively clearing rooms. Also it makes it much easier to not flag your barrel in a window or a doorway. I have a lot of experience with CQB. I love the 500 SPX, my only gripe would be with the ghost ring. There are better iron sight systems available. This one is not bad, just not the best in my opinion. A better option I feel is going with a red dot sight or an EOtech.
Kris, where did you get the longer tube?
The 590 SPX (50771) is available at R&R Arms; 4 days ago, there where 3 available. By closing time Friday (17 April 09), 1 still available; price had gone up ($620.94). If anybody wants it you better do it fast, because it’s harder and harder finding the 590A1.
Hello, I have a Mossbberg 930 SPX, which operates flawlessly. I really like this shotgun. However I have accuracy problems, with the rear sight adjusted all the way down the gun still shots high about 12inches at 50yards with slugs. the shots are grouped ~ just shoots to high. the front sights are fine unlike quite a few other posts on the web about the front sight being bent. has anyone heard of or experienced the same problem??
Any help would be greatly appreciated.

Hi Gerry,
Yeah – same problem here. The rear sight is all the way down, and I’m shooting about 8″ high at 50yards. I plan on calling Mossberg to see what the deal is – you SHOULD be able to adjust the sights to shoot however you want (within reason) and for me, 50 yards is where I’m going to start shooting slugs. My Remington 870 has ghost ring sights and I shoot 5″ groups at 100 yards all day long (with slugs).
I’m also getting some weird spalling/scratches on the magazine tube, in the area where the gas piston rides around it. I’m going to be asking about that as well, seeing as the gun only has about 50 rounds through it at this point, and I wouldn’t expect to see any appreciable wear at this point…..
I’m getting the feeling that the 930SPX may have been rushed out the door….
Actually, just ran across this on another blog – you might take a look at your front sight per their suggestions and see if you can improve on it. It seems like we’re experiencing a common problem: http://www.shotgunworld.com/bbs/viewtopic.php?f=7&t=186115
