New 590R Shotgun Introduced

I’m a Mossberg fan boy. I own almost every one of their offerings. I’m not sure about this one. It’s cool for new users but I already have a version of it that I put together myself (see Mossberg Flex). The mag fed stuff is cool but if you’re a shotgun guy loading shells in the tube is ingrained.
If you are fighting drones in some hellscape (or New Jersey) then blast away!
 
Will be interesting to see the actually weigh of one of the 590MRs with a 20 round loaded magazine.

Mossberg specifications says the gun itself weighs 8 lbs which based on advertising history I think most of us will question that number. Then you add a 20 round magazine for which they give no weight plus 20 rounds of 12 gauge buckshot or slugs say at around 2 lbs. So without any optic, sling or anything else you likely have a 11 plus pound weapons.

Not sure I'd like to carry that all day. Plus a couple of spare loaded magazines.

Hope someone will actually weigh this monster.

I just picked up a 590R…not the magazine version. I got the standoff barrel because it is heavy walled. Unlike most 590 models, it is phosphate parkerized. The trigger assembly is metal and the trigger pull is amazing. It is easier to feed rounds in due to a larger feed opening. I picked it up for 29% off MSRP with no sales tax from Locked & Loaded.

Since I purchased my first 590 in 2003, I've owned and sold, every model of Mossberg 590A1 made, looking for the right one. Mossberg originally designed this 590R as a contract for some country's military use. Whatever the designers have done to the action is amazing. Most Mossberg pumps are extremely stiff out of the box, but the action on this 590R reminds me of my 70's vintage Wingmaster. It has a shorter forend than any 590 or 590A1, other than the Shockwave. The fit a finish on the one I received were amazing....which is not typical of a lot of Mossberg's I've had over the last few years. It may not be for everyone, but the new design just feels natural to me.....especially the enlarged loading ports. Unloaded, with my red dot the 590R weighs just a smidge over 7 pounds, 4 ounces. One other definite improvement is the action release, which is much easier to engage, than on the regular 590/590A1 shotguns.

White Oak, it appears one of the biggest changes is the ambidextrous lever safety. How do you like it as compared to the tang safety?

I'm glad they have finally opened up the load ports. Many of us have been modifying our ports on 500/590 models for years and talking to Mossberg trying to convince them to adopt the idea. Especially glad to see the the forward relief which really helps you thumb in shells during tactical reloading.

Noticed that it comes with both a plain and standoff muzzle. Just curious why you chose the standoff model?

Ernst,

I like the rotary safety....especially with the pistol grip stock. Actually, I think the trigger is as big a change as the rotary safety. The metal framed trigger assembly, with a flat faced trigger, is incredibly smooth and light. The other significant improvement is the action release, it's much easier to locate and operate, the little finned ones on my other Mossberg 590 and 590A1 shotguns.

As far as my choice of the standoff barrel goes, I did it for two reasons....firstly, it is a heavy walled barrel, which just looks a bit more robust, and secondly, I just like the looks of the flared breacher muzzle, compared to the skinny little muzzle with the huge MagPul front sight.

I'm not complaining or criticizing but that does NOT look like a typical 500/590! :eek: I'll have to handle one next time I'm in a gun store--looks interesting! :)

In case he needs to blow the hinges off a door! :D
 
Bobster & White Oak, I suspect at our (atleast my) age we're well beyond the need to blow hinges off doors! LOL

I've never been a fan of pistol grip shotguns mainly due the the different grip angle and how the recoil energy is disburse through your wrist. Now the Shockwave bird's head changed that.

However, with this 590R I suspect there will be some adjusting to find the right LOP length in combination with the pistol grip angle. Not sure how many adjustment notches there are on the AR style rear stock. White Oak can you enlightening us on the adjustability of the rear stock? I'm assuming 3-5 positions?

Bobster, while I agree it's "different" from the traditional 500s and 590s I do like some of the design features they have adopted from the 590M.

While speaking of the 590M, I looked at one and the gun combined with the oversized and over priced detachable magazines are IMO a huge pain to carry, especially in a tactical environment. And then you need to deal with the weight and balance of a load gun. Wonder if anyone on here has bought a 590M and can review?

Ernst, it is a 5 position stock and an extremely generous recoil sensitive pad on it.

BUT he has the option to blow doors off hinges if he wants! :D
I say it is "different" but in a good way. :) It will take some getting used to seeing a new "updated" 590 out and about, but I think it was well done.
 
Bobster, I think the one feature I like best and have advocated for years that Mossberg adopted is the enlarged loading gate port. Many of us have taken a file to our older Mossbergs and basically done what is now standard on the 590R. It really does make a difference if you're tactically (combat) loading while on the move or without looking at the port. Plus the smoother and relieved foward ramp certainly saves your thumb.

But I'm with you on needing to look at and evaluate the lever safety and new slide release. Hard to beat the standard tang safety IMO which has always been ambi!

I do like the new profile of the trigger. I wonder if it was designed in house or bought off from a supplier? Would like to see if it's a retro fit into a Shockwave.

Thanks White Oak for all the insights. If you tear down the gun could you look at the trigger and see if it has any identification marks?

Regards

Ernst, this trigger assembly uses 2 housing pins instead of 1 like on the regular 590 @ 590A1 shotguns. (See the attached schematic)IMG_1639.jpeg
 
White Oak,
Thanks for the participation on this forum. Great info!
The take down pin location is unlike my M590 and M500 shotguns. So no to any retrofit in the immediate future or at all.
I’m interested in the trigger and the trigger experience.
Is there anything to learn in the fire control group that may benefit us all!

Jmm14534, I've just had the 590R a couple days and still just feeling it out. As I mentioned before, the slide action on my 590R is more akin to my '70s vintage Remington 870, than any of my other 590 & 590A1. It's still early in my ownership, so I can't say for sure why the action is so smooth, but one major difference in the action of the 590R, is that it is more like the Maverick 88 in that the forearm and slide are fixed, so that you can't replace or upgrade the forearm.

I usually replace my forearms, so I'm not exceptionally happy with that design feature.....but, if that was necessary to make the action that slick, I can live with the OEM forearm. I've already applied Talon Grip Tape strips to the land above the forearm ribs to add a bit more grippy-ness, so I guess that'll have to do.

I'll share more differences or likenesses, as I dig deeper into the system.
