The Tac 14 Vs. Shockwave – Battle of the Mini Shotguns


Technically these guns aren’t shotguns, so maybe my title is misleading. They fit most of the technical terms for shotguns, but legally since they’ve never had a stock, they aren’t shotguns. These ‘firearms’ captured American shooters with their NFA defying nature in 2017. I own both and love really love the concept, but which gun do I like more? Let’s find out, today we are looking a little Tac 14 vs. Shockwave.

The Tac 14 Vs. Shockwave War – A Battle Rages

Mossberg vs. Remington is basically the Glock versus 1911 of shotguns. Except both are equally effective and modern guns. So are there enough differences to really separate these guns? If there weren’t any differences this Tac 14 Vs. Shockwave article would be quite short. There are plenty of differences that separate these two guns.

A Little Customization Goes a Long Way


The most obvious will be capacity. The Mossberg Shockwave holds 1 more round than the Remington Tac 14. Is one round a big deal? Well in guns with low capacity I’d say so. Additionally, the Shockwave is compatible with the Opsol Mini-Clip which allows the use of Aguila mini shells. These mini shells give you 9 rounds total.

Red Dots for Days

Remington also dimpled the Tac 14’s magazine tube so adding a +1 mag extension is complicated and somewhat annoying.


Both guns have a high degree of modularity. There are tons of different pumps, sighting options, and even brace systems to modify either of these guns. This could be a cut and dry category but the Shockwave 590 is drilled and tapped for a scope mount, and adding a red dot makes this gun extremely easy to shoot.

Modded Out

Is our little Tac 14 vs. Shockwave debate already over? The Mossberg certainly has advantages but let’s look at handling the guns.


The Tac 14 comes equipped with the Magpul SGA pump, and the Mossberg comes with a standard ribbed pump with a strap. I like the strap for safety reasons, but I love proper technique more. As you can see my Mossberg now wears a Magpul SGA pump. The Magpul pump is modular and much slimmer. The Mossberg pump had several screws that held the strap to the pump and those bit the hand frequently, often drawing blood. I’ve owned both over a year and found the strap isn’t needed if proper technique is used.

I Love Muzzle Flash

The Mossberg’s top mounted safety is more lefty friendly, but both safeties are easy to reach with the Raptor grip installed, the same goes for the pump release. The Remington’s safety is much better if you choose to go with a pistol grip and brace set-up.

I mean I really Love Muzzle Flash

The Remington is almost half a pound heavier than the Mossberg. You really have to ask yourself is this a Pro or a Con? These guns recoil a lot, so extra weight does help cut recoil. However, without a stock that extra weight literally weighs on you. Aiming at eye height is a bit more challenging. In a fair Tac 14 vs. Shockwave battle, I can’t really say this is an advantage or disadvantage so we’ll call it a wash.

The Material Differences

Speaking of weight, you may be wondering why the Remington uses a steel receiver versus the Mossberg’s aluminum. Steel is stronger, but I’m not sure how much of a durability difference this makes long term. I’ve never heard of a cracked Mossy receiver.

The Mossberg Shockwave does have the more robust dual extractors. The Remington Tac 14 uses a single extractor. Mossberg extractors are also much easier to replace if they ever warp and break.

Proper Technique is Critical

When it comes to these gun’s finishes, the Remington’s seems superior. I’ve had both for over a year, and the Remington’s seems much more robust. The Shockwave has some nasty scrapes and scratches, but the Tac 14 is still pretty flawless.

Finally what I really like about the Tac 14 is how smooth the gun operates. The Mossberg Shockwave does have a gritty feeling to it. The Remington seems more refined when it comes to the trigger, controls, and pump.

So who wins in a Tac 14 vs. Shockwave fight? We do. I honestly bought both to review and figured I’d sell one when I found the one I liked more. A year later here we are, and I still have both, and that’s not going to change. Both guns are fun, modular, and challenging to master.

Speaking of mastering, I’ll leave you with a little video I did for Govx on handling these guns.

    For defensive purposes, do not use the Opsol Mini-Clip. While fun to use at the range, it is not 100% reliable and it does dislodge sometimes. I used a Vang Comp Systems +1 mag extension which also serves as a great stand-off device. I also had the barrel worked over by VCS, including their porting and it really makes a huge difference in recoil as well as getting tighter groups.

    Thanks for the article!

      The Opsol mini clip has been updated, to the FLEX. It fits tighter in the mag well, and allows a range of mini shell lengths to be fired. The question for users of the clip is not whether it becomes dislodged, that is easily ensured with a piece of duct tape…I use on mine. The question is whether the clip feeds the minis correctly, and whether the mini shells hit hard enough. There will be more on this later, but I have mini reloads with 6 00 buck in them that plow through 2 3/4″ plywood sheets. By contrast, the Aguila buckshot round, which Opsol showed on a video completely going through the FBI Joe Fit gel torso, does not even damage the backside of the second sheet of plywood.
      Put simply, the clip is easily removable for the convenience of the shooter. If they are happy with minis for defensive purposes, use a little bit of tape.

          I think about a month ago. I got the first version for my wife and daughter. On one of my guns, the carrier pushes clip….the carrier just drops lower than it should and hits the clip As for shells FTF,we havent experienced that yet. Certainly can happen, just like short stroking the shotgun fouls up regular shell feeding. With tape, no movement at all.

    Ummm, sorry don’t get it. Chalk and cheese here.
    RED DOT? Are you serious? Laser, maybe.
    Shoulder vs, free hand? That’s easy. No its concealment vs mass.
    Missed it I am afraid. Try again, or are you paid………

      On my Mossy I have a Trijicon and a CTC green laser. What’s not to like? Hit a six inch circle at 25 yards all day long with 12ga. Federal flite control (indoors or out).

    Just wanted to say my Mossy Shock has a steel receiver! A buddy bought a Tac based on this review and was rubbing my face in it until he saw a magnet sticking to my receiver like a tick on an Alabama hound dog. Then I got to rub his nose in it when I loaded 1 more shell in the tube than he could!

    • David Higginbotham 14 August, 2018 at 12:45 Reply

      I don’t have one on hand to check, but could the magnet be holding onto steel inside the aluminum?

    • Hugh Jorgan 17 March, 2019 at 03:22 Reply

      Uh, yeah…the magnet is apparently adhering to something on the inside of the receiver, because Mossy uses aluminum…and there is NO debate about that.

    To me, the Mossberg is a clear winner, especially with Remingtons nose dive in quality control in the last several years. That said, the true point of this article was to stroke BOTH companies, not “pick a superior gun”. Like glossy ads in print gun rags, if you still believe anything you read or see from someone getting compensated for “reviewing” something, you are foolish…

      I can assure you neither Remington Nor Mossberg paid me anything and never have. I bought both of these guns out of my own pocket.

        Thanks for the review and video, Travis. One thing I did to my Shockwave was I had Hans Vang Custom do some work on the barrel. I had him do the Vang Comp mod which does lighten the recoil impulse a bit, but mainly, it really tightens up groups!

        Also, thanks for having served. Make sure you thank your parents for me as well. As both the son and father of soldiers, I know what it’s like to be part of a military family.

      Yeah, not so much. I understand the root of your complaint, but this was written as part of a larger examination of the new mag-fed guns, and not in any way as promotion for either company. In fact, neither company contributed in any way.

    […] Crimson Trace, manufacturer of the LaserSaddle shotgun laser sight has been dropping hints on social media that they may soon be expanding that line. Currently, LaserSaddle only fits the Mossberg Shockwave, but it’s entirely possible we’ll soon see one for the Remington Tac14: both of which we compared recently in Travis Pike’s Tac-14 vs. Shockwave Battle.
