The KelTec KS7 is a fascinating shotgun. It’s a bullpup, tube magazine-fed design that borrowsa lot of inspiration from the KSG. Unlike the KSG, the KS7 uses a single magazine tube that holds seven cartridges. The KS7 provides you with a gun roughly the same size as a Mossberg Shockwave with two extra rounds and a stock. 

The KS7 Gen 2 has recently been released, and we wanted to revisit our accessories article to celebrate its launch and discuss how to make the most of this bullpup, pump-action powerhouse.

The Accessories and Upgrades;

Optics

The KS7 originally had a replaceable carry handle. Users could swap the carry handle for a pciatinny rail to mount optics. The new KS7 Gen 2 comes with a flat-top optics rail standard. This makes adding optics much easier. If you’re like me and still rocking and rolling with the standard KS7, you can drop the carry handle and swap it with a rail from KelTec easily enough. 

The KS7 series uses an inline stock, much like an AR. Because the stock is in line with your shoulder, you get less muzzle rise. However, this requires you to use AR height sighting systems. This means an AR height mount. Luckily, that’s not exactly uncommon. We have plenty of options. 

So for me, this would be one of my upgrades.

Optics are one of the most important Kel Tec Ks7 shotgun accessories that you can buy. They allow you to see your target better and make more accurate shots. There are many different types of optics on the market, so it is important to choose the one that is right for you.

The Keltec Ks7 is a great shotgun, but it can be made even better with the addition of a good optic. There are many different types of optics on the market, from red dot sights to magnified scopes, or just using the iron sights that might come with your firearm. But with a 12 gauge shotgun, choosing the right optic can make a big difference in your shooting accuracy and enjoyment.

The Best Kel Tec Optics That You Can Buy

Red dot sights are a great choice for a Kel Tec Ks7 optic because they allow you to see your target clearly without having to take your eye off the sight.

Red dot sights are also very fast to acquire your target, so you can engage quickly. There are many different types of red dot sights on the market, but I like the Sig Sauer Romeo5 red dot sight.

This sight is very durable and has a wide field of view, making it perfect for Keltec Ks7 use.

No matter what type of Keltec Ks7 optic you choose, make sure that it is of high quality and that it is right for your needs. Optics can make a big difference in your shooting accuracy and enjoyment, so choose wisely!

Weapon Lights

Any and every home defense weapon should have a light. A light allows you to identify a thread and, most importantly, tell friend from foe. In a Gen 1 stock configuration, the carry handle offers you multiple M-LOK slots for mounting accessories. You can directly attach lights or attach rail portions, then lights. 

With the Gen 2, or a Gen 1 with a flat top rail, you can mount a light directly to the rail. There is plenty of room in front of the optic for a light, and this makes it easy to mount and rock and roll with. Because you are limited by the ergonomics, attaching any old light might not be feasible, so I’ve picked a few that fit within the KS7’s constraints. 

Lights should be easy to access and bright enough to cut through any darkness ahead of them. These weapon light salso need to be extremely capable of withstanding recoil. Twelve-gauge shotguns are not known for their soft nature, so the light needs to be capable of withstanding it.

Recoil Management and Muzzle Breaks

You might be surprised how much kick this shotgun has. With the bite of the Kel Tec bullpup shotgun, there’s a few options that you can consider. First is a recoil pad for the buttstock, and secondly is a muzzle break.

When it comes to Ks7 shotgun muzzle breaks, there are a few things to keep in mind. First of all, make sure that the muzzle break you choose is compatible with the Keltec Ks7. There are many different types of muzzle breaks on the market, so it’s important to find one that will fit your shotgun.

Once you’ve found a compatible Keltec Ks7 muzzle break, the next step is to install it. Most muzzle breaks will come with instructions on how to do this. However, if you’re not sure how to install the muzzle break, you can always consult your local gunsmith.

Once you have your Keltec Ks7 muzzle break installed, you’re ready to go. That’s all there is to it! Now you can enjoy the benefits of reduced recoil and better accuracy when shooting your bullpup shotgun.

Here is my suggestions for reducing recoil;

Slings

Slings are important to any defensive, hunting, or tactical weapon. Slings allow you to retain your weapon and keep control over it if you have to use your hands. The KS7’s short nature makes it easy to sling and easy to carry. The tactical sling market has exploded, and most serious shooters have turned to some variation of the quick-adjust two-point sling. 

These are the slings used by the military, police, and professional shooters. Slings are handy to have. On shotguns, a sling can be even handier. When properly adjusted and tightened just right, you can use them to help reduce recoil. The sling can’t reduce recoil by itself. 

It can help shooters engage in proper recoil mitigation. You can use the sling to help you engage a push/pull isometric technique. The sling’s tightness aids your push/pull. The Slign does a lot, and on a KS7 or a shotgun in general, it can be a handy tool for reducing recoil and improving control.

Below are my top picks for slings;

Magpul MS1
  • 2 point sling design
  • Non padded
  • Quick Adjust

Conclusion

KelTec Ks7 shotgun accessories are a great way to turn your already great bullpup shotgun into something even better. 

I love these accessories as they add style and functionality to your Kel Tec Ks7. Adding accessories to any of your firearms is the way to go, and they’re a must have for any Keltec Ks7 owner.
