I just received a new Mossberg 590A1 - my first shotgun, and I am freaking excited about it. I'm about to put in an order to Havlin Sales for spare parts so I'd like to know your experiences with parts breaking or wearing out on the 590A1: which ones will break or wear out first, and which ones are the most important to have on hand?

I did a search and read that spare mag springs are crucial for the 590A1, but is there anything else?

Thanks

[Jorg]

Ammo, lots of ammo.

[swampboy]

Don't have specific info on the 590A1, but have a couple of the "lesser" 500's. If I were you, I wouldn't buy a thing just yet. Go shoot it. Have fun. Shoot it some more. If everything works as advertised, don't worry about it.

I just ordered metal safeties for both of my 500's (probably not even necessary) because I've read about them being a possible weak link. If you've got an A1, that base is already covered.

[Runflat]

I bought a metal safety with a tab on the top to make it easier to manipulate. I am still putting my 590A1 through its paces before I make modifications to it. The safety is a definite change that I want to make though.

[throdgrain]

Buy 500 cartridges and shoot them as quick as you can. Nothing else required :)

[DaleCooper51]

I agree with others, lots of ammo.

Run the gun until it is second nature, then run it some more.

[THE DARK KNIGHT]

Ammo, lots of ammo. Slugs, Buckshot, Birdshot, all kinds of sizes, all types of shells. Have a smorgasboard of ammo.

And leave the gun as it is! The only accessory you need on your 590a1 is a sidesaddle or an elastic stock sock that holds the 5 extra shells. And a good sling. If you have the bayonet lug have an M7 bayonet around too of course. Don't go mounting crap on it or anything, it's a great weapon in its most basic form.

wearing out on the 590A1:

Bah! nonsense :D

Fantastic Shotgun, you'll enjoy every time you shoot it!

extras for it- well if you want ghost ring sights Mossberg has that down to a science. A side saddle if you want, different stock options of course and really just slings and sling mount options are left....

[NoirFan]

Guys, I just want to be clear that I am looking for recommendations on replacement parts, not accessories. I want to know what is most likely to wear out or fail so I can keep a few on hand. If the answer is nothing, well, that's great too.

I plan to keep the gun mostly stock for the time being, until I can get to a class and figure out what I need.

Thanks

Your trigger finger

[Schofield3]

On a more serious note :D, you could buy an extra firing pin, mag spring, trigger group, barrel, action bar, really anything you want extra of….

True, but if nothing breaks in the first couple hundred rounds, it's very, very likely that you'll have no problems for the first several thousand.;)

Mossbergs have notoriously weak magazine springs straight from the factory. Get a Wolff brand spring and cut it down to 6"-8" past the end of the mag tube. After that, as much ammo as you can afford.

[RandKL]

Mossbergs have notoriously weak magazine springs straight from the factory.

They do? New one to me.

The prob with long magazine guns like the 590a1 is that the mag spring has to go from one shell in the tube (very little resistance) all the way up to eight in the tube (LOTS of resistance)....and that's a lot of compression for a mag spring. You simply can't make a coil spring that's just as stiff at both ends of the spectrum. It might be stiff when loading (and cycling) the eighth shell and feel quite weak when loading (and cycling) the last shell. There is no fix for that. Replacement springs are simply stiffer, not better. Where they're stiffer with one or two shells, they're often too stiff when working with the seventh and eighth.

As to the 590a1 wearing out, it won't happen. The only part prone to wear because of the design is the finish on the inside of the receiver. It'll scuff up as the gun breaks in. It won't wear out, though.

Good gun. Congrats.

[BullfrogKen]

It won't wear out, not in normal, "domestic" use anyway.

Had mine for 7 years now. I know of others in my group of friends who've had them for twice that long. Thousands of rounds, I've heard of nothing breaking or wearing out on them. The magazine spring might be your first replacement part.

Some guys have put in a high visibility follower, but that's just personal taste.


Get a simple strap sling, a case of ammo, and go use it. They're rugged shotguns, one of the only ones I know of that are actually drop safe. Short of abusing it, you'll have a really tough time breaking something on it.

somewhere in the million round mark youll have to replace your shoulder but other than that your good to go

you might want a spare mag spring but thats a very iffy might because i have around 11000 rounds through mine and not even a hickup

your grandkids might want to invest in minor parts but you shouldnt worry about a thing

[NoirFan]

Thanks guys. So it seems like the consensus is magazine springs MAYBE, and nothing else. I can definitely live with that.

On a related note I took it out last night for the first time and had a great time! I'll post a "range report" and first impressions later.

[Hans Esker]

A bayonet you silly goose!

I will get one of these guns someday, but I already have the bayonet for it: the OKC3 Marines bayonet.

I've bought 15 Mossy's in the last 6 mo. $3050. 100-rds of #00 for each. Ready for the apocalypse. (Say Jorg; $50 to your favorite charity if you can prove you belong to the Second Amendment Association.) Tad.

[DAVIDSDIVAD]

I bought a 590-ized Wolff spring from some guy on one of the other gun forums and it is great.

I really have to seat the eighth round, though.

[Zach S]

Ammo.

I haven't had any problems out of my magspring. It seems pretty weak on the last round, but no more than it did 5 or 6 years ago when I got it, and its never failed.

[Onmilo]

Sling, many to choose from.

Limbsaver recoil pad. You have to use one to fully appreciate the benefits!

Trijicon RMR, J-Point, Dr. Optic dot optic and mounting platform, much better than rifle type sights when mounted to the shotgun.

Colored, anodized magazine plug from Brownells, I like the red ones, you can tell at a glance the shotgun is loaded or empty.

+1 on the Wolff or a Chrome silicone magazine spring, the factory springs do weaken noticably after many load/unload cycles.

Use a dump or grab pouch for spare shells.
The side mount shellholders are all somewhat flimsy and only add excess weight to an already fairly heavy gun.
Loops on the sling add unneccessary weight and cause the sling to flop around.
Stock mount elastic bands tend to abrade the face and move around on the stock unless screwed or glued into place.
The screw on the stock types tend to just get in the way.
Forget the "Frito Bandito" bandoleers too, shells are exposed to the elements, the bandoleers tend to move around and make grabbing the shells from the loops slow and difficult and red shells stuck in the loops make an inviting target..

[DAVIDSDIVAD]

I'm going to have to chime in again and correct my previous post.


The only reason I replaced the original spring in my 590 was because I found a guy on another forum who cut and shape the springs to size, and would send me one for $7.
Basically, I did it because I thought it would be "cool."

I still have the original spring as a back up.

At that time, I'd put about a thousand rounds through my shotgun, and had loaded/unloaded it exponentially more times and the spring still felt the same.

[inSight-NEO]

I would suggest replacing the stock mag tube spring with a Wolff spring. Dont buy the "pre-fitted" spring; rather, get their "generic" heavy duty spring instead. Then cut and shape to fit as needed.

My 590 jammed up within a few rounds when I first shot it...but, it continued to function relatively well the rest of the day despite a few misfeeds and such. Now, when I got home and proceeded with the breakdown, I noticed the stock spring had actually bent back on itself and was quite distorted. I contributed this to the fact that the Mossberg springs have tapered ends vs. the usually "straight" ends found in my other shotguns. After I replaced this spring with a Wolff spring (which I cut and shaped), the previous issue(s) disappeared.

In addition, might I suggest going with a Vang Comp stainless steel follower as it seems to me that the stock follower is a bit shallow.

Also, if you have the front bead sight setup (and are interested in using this weapon for HD), I may also suggest going with a Meprolight tritium front bead.

I have everything listed here on my 590 and have yet to encounter issues with any of it.

[Lee Lapin]

IF I had a 590 I expected to run forever, I'd buy an extra complete gun identical to the first, and then lay in a few spare parts just on GP:

-a complete trigger plate assembly (that way any fire control 'fix' is pretty much a drop-in)
-a spare bolt assembly (ditto)
-spare receiver pin or two
-a replacement magazine tube, extra mag springs and magazine cap
-an extra barrel
-an extra stock, and a spare forearm/action bar assembly
-a couple of firing pins and springs, extractors with springs and plungers, replacement parts for the safety assembly, ejectors and screws etc.

That's overboard for most people, admittedly, but if you want to have a gun that can be kept running, you need to be prepared to fix anything that breaks, is damaged or comes off and gets lost. I run 870s with that in mind, and if I can't take a stripped receiver and build a complete working gun out of my spare parts bin without buying parts, then something is wrong IMHO. The advantage with 590s is that the magazine tube is owner replaceable, not so with 870s. And keep in mind, the list above should realistically support a half dozen 590s for a long time, unless they are in the hands of gun-destroying klutzes.

fwiw,

My thoughts exactly...Im currently "in the market" for another 590A1, but with a shorter barrel. Either way, in wanting another one, I have thought about the advantage(s) of having, essentially, two identical weapons.

But, this is not something I do on a regular basis as there are just too many weapons out there Id like to own vs. spending all of my cash on duplicates. ;)

[Lee Lapin]

NEO,

Only problem with the 'buy a duplicate gun' approach is that what tends to break, wear out or get lost on one example of a given make/model is probably going to eventually happen to the other copy as well. It's embarassing to wind up with two guns broke the same way 8^)- therefore, I think a reasonable supply of likely spare parts is a good idea no matter how many copies of a given gun are in inventory.

JMHO, YMMV...

Agreed. Thats why I limit "duplicates" only to proven platforms/models as well as those I tend to shoot the most. In addition, I do try to keep various "spare parts" around...as needed. Of course, I tend to "duplicate" shotguns only. When it comes to handguns, I favor variety.
