First Look: Mossberg 590 Shockwave Non-NFA Firearm

By Drew Warden - February 8, 2017

Many people over the years have avoided purchasing or building a short-barreled shotgun (SBS) because of the tax stamp and NFA paperwork required to do so. Well, Mossberg’s new 590 Shockwave represents a way to get pretty darn close without any of the hassle of a typical SBS.

With a barrel length of 14 inches, the Mossberg 590 Shockwave is certainly shorter than most standard 16-inch barreled shotguns. However, this, paired with its overall length of 26.5 inches means that instead of falling into the BATFE’s (Bureau of Alcohol, Tobacco, Firearms and Explosives) SBS category, it actually lands within the organization’s general “Non-NFA Firearm” classification. Because of this, the firearm requires no tax stamps for transfers, meaning less inconvenience for buyers.

At its core, the new 590 Shockwave still relies on Mossberg’s proven pump-action design, which utilizes non-binding twin action bars, positive steel-to-steel lock-up, an anti-jam elevator, dual extractors and the company’s classic ambidextrous top-mounted safety. And of course, the anodized aluminum receiver is lightweight and durable, and as an added bonus, the magazine tube features a clean-out cap.

What makes this gun especially unique, apart from its shorter, 14-inch barrel, is its pistol grip and forend, both made by Shockwave Technologies – hence, the Shockwave name for this model. The grip has an enhanced textured finish, as well as a “bird’s head” style profile. This allows for increased stability and control when firing the 590 Shockwave. Manufactured from glass-filled polymer with a non-reflective black finish, the grip is durable and has a length of 5.25 inches, helping the gun hit that 26.5-inch overall mark. The forend, on the other hand, is a cob-style, tactical design that incorporates a strap, also for improved control and smoother operation. It also helps keep your hand where it should be – on the forend, and not forward toward the muzzle.

The 12-gauge Mossberg 590 Shockwave Non-NFA firearm accepts 2 3/4- and 3-inch shells and has a 6-round capacity. The 14-inch barrel wears a matte blued finish and features a bead sight.

The MSRP on the new Mossberg 590 Shockwave Non-NFA firearm is currently listed at a very affortable $455. For this reason, it should be an attractive option for anyone looking for a compact, capable scattergun option for home defense or fun trips to the range.

In a disclaimer section of its news release on the new 590 Shockwave, Mossberg also encourages potential buyers and users to check their state and local laws to ensure that the firearm is legal in their area. While it’s classified as a “Non-NFA firearm” by the BATFE on a national level, classifications may be different at state and local levels in some locations, which is why the company recommends (and we would second this) checking with local authorities on the legality of the 590 Shockwave in your locality.

Is there some in the country already?
I bought two raptor grips and just assembled my 590 14" kit and used one of the grips!
They said it was a pistol grip but really it isn't, it feel good, a lot straighter than a pistol grip and should be easier on the wrist, I found the pistol grips were very harsh! The color of the 14" kit I have is a very dark grey Parkerizing finish, not blueing. However, the ones mentioned in the article may be different!

These are cool and all, but in our market where we don't have NFA regulations I'd rather have a 8.5" barrel with a full stock for the same length, or a 12.5" for only an according couple inches more.
 
People on both sides of the border have been piecing together these exact shotguns for quite some time now.

It's about time Mossberg made them straight from the factory this way. Good on them.

Overall length still needs to be 26.5 and that is exactly what these are! If you shorten the barrel by an inch then you have to add to the stock, I will take the extra barrel length!
Now, with a mag fed pump, or even semi, I would go shorter as you can still get a reasonable amount of ammo and quick change Mags!

Yep that's mine, they are nice, I put the other grip on a 500 door breacher with 18.5 inch barrel!

An 8.5" with a short Hogue stock is only 27", granted its not going be a Mossberg and you're giving up 2 rounds, but its going to be a lot easier to shoot than an awkward PGO.

I understand what you mean but it is more for the cool factor and if shooting from the waist it is very comfortable, unlike the pistol grip which is a p o s, got two in the drawer now collecting dust!
 
All you need to do is add the perfect accessory for shooting from the hip;

You really did NOT, need to show me that, now I need one, or two, I just put magpul furniture on my 590A1 mariner, it is awesome and shoulders great, comfortable, excellent cheekweld! They look kinda funny but the ergonomics is there, but, it needs one of those lasers!!
Edit, not sure if there is a spot on the raptor to fit it! Gotta go look!

lots of discussion on the legality of firearms under the supposed 26 inch legal length in Canada on this site. i always like to point out the legality of the mares leg style rifles at shorter lengths of around twenty three inches, non restricted class. not to take away from this thread i am glad our American cousins can have this firearm without jumping through the class three hoops.
 
Hee Hee , GG&G make this mount for the 590 as well , Wolverine can get one for you to go with your new "Laser" . lol

Shockwave Technologies should improve their Raptor grip by adding some finger grooves or somehow shifting the "beak" of the birds head further forward towards the trigger. Push-pull is what you want to do shooting a 12 gauge shotgun in this configuration but when you pull on the raptor grip their is no support provided by the shape of the grip, this coupled with the long reach to the trigger on a Mossberg shotgun makes for a difficult grip.

The original speed feed witness protection is way better..... but it's too short. They need to make an improved model with the ergonomics of the Witness Protection and the extra length of the Raptor..... in my opinion of course.

On my raptor grip I built up some support with hockey tape.... not very pretty but way better.

This picture sort of shows the lack of support,

Even something like the Tyler T-grip for Smith and Wesson revolvers but made for the raptor grip might be nice.... easier just to fix their mold though... :)
