New Mossberg 990 Aftershock

I've been keeping a careful eye on this thread, and it's wonderful to see all of the thorough comments from people who have already used the 990 Aftershock. Mossberg made some intriguing decisions with the single extractor configuration and gas system architecture. A threaded barrel would greatly increase the platform's adaptability, as mentioned in the comments.
Here are some postings that are worth looking at if you're wondering about current availability or want to see what's available: 990 Aftershock at Mossberg. Although prices are still high, it's useful to monitor the current state of the market.
 
Happened to be looking this morning at the availability of the Aftershock and with the exception of one or two online dealers no one has one in stock.

Most of the prices are still beyond $900 for a basic model.

Wondering how overall interest and actual sales have been?

Regards

Florida Gun Exchange in Ormond Beach (Daytona) has them in stock according to their website. $900 + $58.50 sales tax and probably $5 FFL fee if you bought it over the counter...

It's been awhile since I was on here!

I picked up a 990 a few weeks ago, and have been working my way through it. I have the 930 SPX, with over 1k rounds, mostly dove/quail practice, with a hundred-odd 00 buck and a few slugs. The 990 is everything the 930/940 should have been, out of the gate.

Not a lot to add to what Airborne said, other than that the bolt close/shell release has the rear-bridge, preventing the spontaneous shell drop with an inadvertent rear-press that was initially billed as a "feature" on the 930, but was very much a poop-where-you-eat affair. For folks with Benelli experience, it was a trip back to the early '90s, when the M1 first came to the U.S..

The forward action spring is an upgraded and modified Benelli M3 style, and a natural evolution of that design in a gas platform.

The piston is all but a copy of the innovative SBE stainless part, and works very well.

Mag tube length is a touch longer than the Shockwave, as I can easily get 6 rounds in with a S&J +1 extension, whereas I had to use the slightly longer Briley to work in the Shockwave.

The 930/940 Truckee forend will fit, with a bit of inletting in the polymer receiver coupler.

Despite my best efforts, I cannot get the cheekweld technique to work for me, but, with an Ed Sherman sling and a stubby foregrip, it does a quick & easy, and accurate, push-out, ala the old SAS techniques with the MP5k in a harness.

Really, REALLY, liking this one!
 
Thanks for the update and glad you like the new 990.

Haven't seen many followups on them since the release.

Regards

Great. Just when I'd talked myself out of getting one. :)

I would say, if you want an auto, but don't necessarily want the short barrel, I would absolutely recommend the 18" version (anybody seen one of those?!).

Talking about the cost, Mossberg is still pretty much the Romanian WASR of the shotgun world. My Shockwave had sharp edges from stamping the slide rails and shell latches, and my (IIRC) right latch was not correctly cut to engage with the slide rail, so I initially had feeding issues. The 930s were better, but still, lots of edges & catches in the system.

NONE of that in the 990. Granted, I have a sample-size of one, but this is a very well machined & fitted gun. Much like comparing an old WASR to one of Jim Fuller's Rifle Dynamics AKs.
 
I hearing that the Aftershock in a SBS configuration with a stock is having some cycling issues. Not ejecting spent shells. Especially low brass.

However, in it's original configuration, where you don't "manage" recoil so much, it seems to work fine.

I suspect with the suspension of the $200 tax on SBS more folks will be add a butt stock to either the original Shockwave or the Aftershock.

Has anyone seen any Aftershock cycling issues?

If you buy the Aftershock (birds grip) model and plan to Form 1 it - he mentions in this video the gas system is different on the stockless vs. the actual Form 4 SBS version that is being made now - cliff notes is that it may not cycle the lower FPS stuff occasionally because the system was not intended to be stopped from rearward movement with a stock on it and a shoulder as a 'wall' to speak


Personally - the 990 SPX with Magpul stock and 18.5" barrel is HIGHLY on my radar (I'm not an NFA guy) - I'm in the market for a companion to my Beretta 1301T and the A300 Ultima Patrol fit the bill, but stock options are extremely limited - this is a complete package and a robust gas system design, oversized controls, and optic cut on the receiver so this may end up being the one added
 
I applaud Mossberg for clarifying the issues with the original Aftershock cycling when converted to a SBS.

It will be interesting to see some field trials of this new 990 SPX. I personally would replace the Magpul stock with a Hogue 12 inch LOP if running tactically.

Me as well - they knew people wanted a stock and they gave them a direct option gassed appropriately -

I appreciate the Hogue for its low weight, have not owned one in years but remember it being decent for me - but let me tell you, anything I have that can fit an SGA (and isn't wood stocked) gets a Magpul stock - some may love it and some may not-

You can replace the Magpul buttpad with a thinner Kick-eez direct fit one to shave it down to just about 12" total LOP with no spacers, I personally like using the X22 Hunter rubber buttpad which is even thinner, I get mine down to about 11.75" LOP which is amazing for me - (If you look at my gray Magpul furniture 590 in the other thread you can see the X22 buttpad on it)

And the fact I love the ability to add dual QD sockets right on the center of the stock, and the grip angle of the Magpul is just so comfortable -

My FFL said when available from Lipseys, the 18" version should be about $1k out the door - which honestly, considering its a direct competitor to Beretta, offers Magpul stock out the box, optics cut, and QD's, I do think this one may be the winner of my next semi-auto as of now -

Beretta just released info that their 12" LOP stock from the 20gauge that was recently released, will be available and fit the 12ga models and sold from them, but knowing Beretta price points its going to be a $200 upcharge and at that point its north of the Magpul 990 SPX so besides aftermarket support I would almost go with the 990 if I had to pick one-
 
The best part is we all have choices and the ability to fine something that works for each person.

Tactical shotguns are my passion and most (all) models need to have both DIY and commercial available mods to outfit a good tactical gun to personal tastes and operations. I know of none today, in original factory configuration, that fit the bill.

If you go back to the beginning of this thread we discussed the gas system which some of us thought was a clone of a Turkish Mossberg system. One of the lingering problems is we've never seen a truely technical review of the system beyond a few teardown pictures. But no surprise that, like the Shockwave, individuals wanted to add a stock. And a few did pony up the $200 only to find the cycling issues of the original 990 Aftershock. Despite inquiries with Mossberg this is the first time that I know about that Mossberg has admitted to the issue and indicated the engineers when back to the drawing board. I certainly hope the new version will run correctly.

Hopefully Mossberg will release some technical data on the both versions. Sure would be good if we could see an xray video of how the system operates like the the one we have on hte 500 series.

Price - I personally think the prices of the 990's, in whatever configuration, are over priced. And alot of the Shockwave owners I suspect are reluctant to step up to the counter. Old Shockwave owners, like myself who bought one the first month they came out, should be prime targets for 990 sales given many have thousands of rounds through their Shockwaves. Just saying!

I agree with this sentence 100% - the only tactical shotgun I know that comes close, is the 1301 Tactical Mod2, but it is now a $1600+ gun, a far cry from 8 years ago when I picked mine up for $650!

Despite inquiries with Mossberg this is the first time that I know about that Mossberg has admitted to the issue and indicated the engineers when back to the drawing board. I certainly hope the new version will run correctly. According to Jeremy at Mossberg, the new stocked versions will, and it seems based on the videos I've seen discussing with him that the 990 Aftershock really should be kept in 'out of box configuration' in order to ensure maximum reliability.

Hopefully Mossberg will release some technical data on the both versions. Sure would be good if we could see an xray video of how the system operates like the the one we have on hte 500 series. Doubtful we'll get a deep technical dive but I'm hopeful.

Price - I personally think the prices of the 990's, in whatever configuration, are over priced. Agreed - When you justify something by saying 1k for a new semiauto shotgun is 'not bad' then I guess we are all accounting inflation! And alot of the Shockwave owners I suspect are reluctant to step up to the counter. Old Shockwave owners, like myself who bought one the first month they came out, should be prime targets for 990 sales given many have thousands of rounds through their Shockwaves. Just saying! You would think you definitely would be - the nice thing for Shockwave owners is those who didn't SBS it yet now can do so for no added cost really! It was always a perfect SBS host weapon in my opinion - a 12" LOP Hogue stock would be perfect on it!

Ernst - love chatting with you (see my notes above in your post in bold and italics)! Tactical shotguns are a passion for me as well, as I don't hunt and feel that a tactical shotgun is an excellent defense choice in almost all scenarios. I'm normally not someone to 'buy something new to market', so I'll wait till these 990 SPX's (my preference for the 18.5" barrel) trickle in, see if I can get my hands on one locally in person to check out the internals and gas system components, and hopefully it would be a winner.

The only thing the Beretta has on it in my opinion is out of the box price, and greater aftermarket support, which may or may not be needed with either. I like the ability to add Beretta's pro lifter to the trigger group (keeps lifter out of the way when loading), and although its not optics ready, there is plenty of support for direct mount optic plates for it.
 
Being as old as I am in my 9th decade my hunting days with a shotgun are mainly over but given my background my focus continues to be tactical use of a shotgun against four legged predators and the other types of varmints.

I appreciate your comments and agree with them.

One of the issues many don't focus on with a tactical shotgun is balance. I see too many add ons which apprear to be installed without really understanding how the balance point of a weapon is effected and how that impacts effective operation, especially one hand shooting and the ability to shoot from either shoulder in tactical situations. IMO modifications should be simple and well thought out and none of this tac-cool stuff everyone is trying to sell you. These guns are typically configured for specific situations be it home defense or CQB and for most of us our property dictates both the tactics and the gun configuration. Most situations occcur within 5-7 yards!

I seriously doubt Mossberg will ever share the technical aspect of their gas system. However, I hope someone on this forum, who owns either model, will start a technical discussion thread where we can all look at pictures including measurements and discuss the operation of the system.

Regards

I agree on balance - sometimes I even wonder with the aluminum handguard craze on the market, is adding 3/4 of a pound of metal handguard at the front of a front heavy shotgun noticeable? I would think it is -

Although with short LOP and a more compact weapon it’s less noticeable.

I’d be happy to do the forum a solid and take donations towards me getting a 990 Magpul so I could tear it down bare and give you every detail of the system! Although only about 10 of us here on any given day -

I did read in one of the press releases some components have nickel boron coating (a good thing) like the hammer, mag tube? And piston - I also read the action is proven similar to a Benelli M1 but don’t know how true that is -

Only slight nitpick I have is the mag extension on the 18.5” model comes about 1/4-1/2” ahead of the muzzle so it will always get excess blast on it -

the aftermarket support on the 940/990 also I haven’t don’t enough research on but it’s not a bad package overall

I still may end up with the Beretta A300UP, but since seeing the 990 SPX with Magpul stock honestly it closed the gap for me and will be a coin flip. The Magpul stock can fit me perfect out the box while the A300UP I need a shorter LOP

Another difference is the Beretta is supposed to be a good bit lighter than the 940/990
 
Ricky B., So is there a minimum donation you might be looking at? LOL

I'm sure a few of us oldtime, retired guys, who live on fixed incomes, could collectively raise $10 to $15 dollars!!!!!!!!!!!!!!!!!!!!!!!

Cadd been selling junk to invest more dollars in his sports car build. And Meany, is likely saving money from not needing to do yard work at his new digs! LOL

But thanks for the kind offer.

Couple of serious thoughts for consideration.

You can take a dowel rod and afix it in a vice and see the exact balalce point of your shotgun in different configurations.

Totally unloaded -
Magazine loaded -
Magazine and chamber loaded -
With a loaded side saddle -
With a sling -
With a mounted weapon light -
and to determine how any additional modification impacts the point of balance.

Balance and overall length define the maneuverability of the weapon for tactical situations.

In many HD or CQB cases you are actually only using one hand to hold the weapon as you maneuver, hold a handheld flashlight and/or open door knobs. Plus you feeling you way along walls with your hand or your shoulder. A well balanced gun really enhances your abilities to clear a facility and shoot with one hand and/or quickly move the gun from shoulder to shoulder as the clearing process occurs.

I wouldn't have any hesitation about the magazine tube extending beyond the muzzle even up to the length of a single round. Might get a little powder build up but not a big deal. Many folks who use weapon mounted lights mounted even with hte muzzle and get the same build up on the lens but easy to keep clean after each shooting session.

I'm in no way an expert on the 930/940 other than reading some of the user comments both good and bad. But we have several members who use both and I'm sure they would be happy to discuss their views.

Regards
 
Mossberg did advise the 18.5" SPX 990 version is a one piece mag tube with metal sleeve cover (same as 940 Pro) - they also ship with the RMR adapter plate in case you don't want to use Holosun K footprint for the optic cut on receiver

Sounds excellent to me! Don't know if I mentioned, but my FFL got me a price, out the door from Davidson's when they become available, at $1,010 (including tax)

Seen a few creep up on Gun.deals for upcoming stock, looks like street price should be low to mid 900's before shipping and/or tax so you should be able to get these for just about or under $1k out the door - which is a phenomenal value in my opinion!
 
Starting to see some Aftershock prices in the $860 range on line if anyone is looking to pick one up.

IMO still high as compared to the Shockwave which, depending on the configuration, are now running from $400 to a little over $500.
