The Kel-Tec Sub 2000 is a small folding rifle with many accessories available after-market. With so many options available from places like MCarbo, it can be easy to become overwhelmed. We’re here to tell you which three accessories we think are the most important, with a few honorable mentions too.

Firstly, if you are unfamiliar with this unicorn of a rifle, here’s a video review from Hickok45. It’s a solid watch even if you already own the rifle, but if you’re just here for the MCarbo accessories, feel free to skip on by.

Why own a Kel-Tec Sub 2000?

For those of you still on the fence as to why you would even need a Sub 2000, let’s get you filled in first. The Sub 2000 is a small folding camp rifle designed to shoot pistol calibers. Practically speaking, the weapon was designed as a camp site or sports shooting rifle. It also works great as a small folding rifle for those of you who are into maintaining bug-out bags.

Here are some other uses for the rifle.

  • Teaching children to shoot.
  • Varmint rifle.
  • Day plinking at the range for fun. (Cheaper than rifle ammo!)
  • Emergency vehicle weapon.
  • Bedside rifle for home-defense. (Self-Defense Ammo Only!)

Here are the specifications of the rifle as Kel-Tec has them listed on their web-page.

Kel-Tec Sub 2000 Specs

Let’s move on to those accessories from MCarbo you need to turn this little rifle into a power house.

Kel-Tec SUB 2000 Pro Trigger Job Performance Bundle

Kel-Tec Sub 2000 Trigger Kit

Depending on your intentions with the rifle, the first thing you may want to upgrade is your trigger group. While the stock Kel-Tec Sub 2000 trigger group is definitely not a must upgrade for individuals using the rifle to teach their children weapons handling, for others it may be a necessity.

Out of the box, the Kel-Tec Sub 2000 boasts a hefty trigger pull weight of around 10 pounds. For some shooters, especially individuals who may want to use it for home-defense, this is not ideal. Using this upgrade kit from MCarbo will net you an immediate 50% reduction in the overall trigger pull from ten pounds, to just under five.

Another bonus from this upgrade kit is that you will fully eliminate any trigger and trigger guard flex that is present in the OEM standard version of this folding rifle. It also comes with a complete upgrade for all of the receiver pins and screws, replacing the aluminum OEM standard pins and screws with black oxide carbon steel grip pins and screws.

You can see a full tutorial on how to install this kit in the video below.

Kel-Tec Sub-2000 Recoilless Charging Handle

Kel-Tec Sub 2000 Recoil Control

If recoil is a concern with this blow-back operated folding rifle, then this upgrade is a must. The recoilless charging handle from MCarbo boasts a 68% reduction in the overall felt recoil, and only adds 2.2 oz to the weapon. On top of this, the charging handle also acts as a minor upgrade to the stock charging handle, giving the end-user more control of the weapon.

Reducing the recoil by 68% happens because of the extra weight added to the charging handle. Because of this extra weight, the blow-back momentum of the operating group slows. As a result, felt recoil reduces dramatically.

Here’s a video on how to install the kit from MCarbo.

Kel-Tec Sub 2000 Quick Detach Single Point Sling Mount

Kel-Tec Sub 2000 Sling Adapter

Slings. This is a discussion we can have for days. Who makes the best sling? What is the best sling style? It doesn’t matter in the end. If you cannot attach a sling to your rifle, then what even is the point of having a sling?

MCarbo makes, without a shadow of doubt, the best quick detach single point sling mount for the Kel-Tec Sub 2000 that exists currently. It’s lightweight, coming in at just under a half an ounce, and machined out of a block of 6061 aircraft grade aluminum. The sling mount also works on both the generation I and the generation II version of the Kel-Tec Sub 2000.

You can find the installation instructions in the video below.

With these three accessories alone, you can upgrade your Kel-Tec Sub 2000 into a beast of a firearm for just under $250. You’ll improve your trigger pull, reduce flex in both the trigger and trigger guard while upgrading the pins and screws of the receiver to be more long lasting, drop your felt-recoil by almost 70%, and give yourself the ability to use your favorite sling all in about an hours worth of work on the gun bench. If that alone isn’t enough for you however, here’s a couple more honorable mentions you can pick-up.

The Honorable Mentions.

These, in my opinion, are not needed upgrades. They will however drastically improve not only the performance of the weapon system, but also help you as a shooter while using the Kel-Tec Sub 2000. Most of these items will come down to personal shooter preference. We highly recommend you handle your stock rifle before you directly make these purchases.

Kel-Tec SUB 2000 Rear Tactical Folding Sights

Kel Tec Sub 2000 Rear Sights

If you’re a giant of a human being like I am, then you might consider going with these tactical rear sights. The stock sights from Kel-Tec aren’t bad, but when you’re a big dude using a little rifle, you need to fight for every little upgrade you can get. These sights make it much easier to get a cheek weld, which in turns makes it much easier to get into a proper firing position.

Extended Magazine Release (Glock or Multi-Mag)

Kel Tec Sub 2000 Extended Mag Release

People with man hands can appreciate this one. The OEM Kel-Tec Sub 2000 mag release is a bit small. For some, this means that dropping your magazine actually requires you to break your shooting grip to release the magazine. For obvious reasons this is not an ideal situation to have in a gun fight. Before you go off and buy this out the gate, manipulate the weapon system and see if it’s something you need. Personally, it’s a must have in my book, but you may find that the stock magazine release is perfect for you.

Bolt Tube Cover

Kel Tec Sub 2000 Bolt Tube Cover

This is on the honorable mention list because it’s a shooter preference thing. For you, you may enjoy the stock bolt tube of the Kel-Tec Sub 2000. In my opinion, I needed something a little extra. Before you go off and buy this, wait to see what you think of the stock bolt tube.

With the MCarbo Bolt Tube Cover, personally I found it much easy to obtain a proper cheek weld. Stack this on with the upgraded iron sight listed above, and shooting this little folder becomes an absolute dream. Again, this is a shooter preference alone. If you find that the stock firearm is running perfect for you, you may want to skip this one.

Final Thoughts.

The Kel-Tec Sub 2000 is an outstanding and versatile little firearm. If you’ve managed to get your hands on one of them, then we hope this guide was useful.

Regardless, if you’re one of the lucky few who have obtained one of these unicorns, let us know in the comments. We’d love to hear from you! If you’re still on the fence, make sure you pop back up to the top of the article and take a look at Hickok45’s review. He definitely showcases just how fun the Kel-Tec Sub 2000 can be to shoot.
