So you got ya one of them fancy little folding rifles: the Kel Tec Sub 2000. I know what you’re like — you can’t leave a gun well enough alone, so customization must occur. If you are wondering what you can tack onto your Sub 2000, you came to the right place. We’ve researched some of the best Kel Tec Sub 2000 rifle accessories and upgrades available and we try to update the list occasionally. 

But first…CAPITALISM!

⚠️ Before ya go hunting Kel Tec Sub 2000 accessories for sale, be aware! Putting aftermarket accessories on a Sub 2K can be more of a pain in the ass than on other models of pistol caliber carbine. That’s a byproduct of the 2k’s ingenious design (in particular its folding capability), but it’s definitely not insurmountable. 

Read on and we’ll explain. 

Surefire M140A Micro Scout Light 

Every tactical or home defense long gun needs a weapon light. In fact, after your sling, it should be the first thing you put on there. Hell, maybe before your sling!

Anyway, there are plenty of good weapon-mounted lights to choose from, but finding one that would complement the sleek design of the Sub 2k is a challenge. Going too big can make the lightweight gun muzzle heavy and enlarge its footprint when folded. Enter the Surefire M140A Micro Scout light

The Surefire M140A is an LED light that runs on a single plain Jane AAA battery. Its small size limits the light to 300 lumens and about one hour of continuous run time. But given the ranges the little Sub 2K is to be deployed, the brightness and longevity of the light on a single charge is likely to be more than adequate.

What is gained in exchange is a lightweight aluminum tubed light that comes in at less than 4 inches long, .6 inches wide, and under 3 ounces. The M140A comes with an LPM or low-profile mount to adjust the light relative to the rail section it is attached to.

MCarbo Optics Mount 

Finding the right optic mount for the folding Sub 2K design will be a bit accessory hassle. Mounting an optic on the Picatinny rail kills the gun’s ability to fold. MCarbo came up with a creative means to allow the mounting of red dot optics to your Sub 2k. This optic mounts just in front of the sights and does not attach to the M-LOK slots. Instead, it connects to the rear of the handguard via four bolts. This provides a consistent and stable platform for an optic.

I think moving bolts makes it a build, but I also think milling an 80 percent lower makes me a gunsmith so…

Where do you begin the upgrade process? The trigger? A specific spring? A better grip? Add a red dot to augment an iron sight arrangement? Happily, there are sufficient aftermarket upgrade items to improve just about any aspect of your Sub 2K blaster.

When it comes time to fold the gun, the optic folds out of the way and gives you no issues when folding the weapon. The Mcarbo optics mount sets the optic low enough to co-witness with the iron sights and is the only Sub 2k scope mount (that we’re aware of) that allows co-witnessing. This simple design makes it very easy for me to mount a red dot to my firearm.

MCarbo offers more Sub 2000 accessory options than any other company I’m aware of. I could write an entire article about the greatness of their products. Make sure you check them out beyond their optics mount. 

 

MI Gen2 Sub 2000 Mini Optic Mount

Another way to throw your optic on there is with this mount from Midwest Industries. It’s just a small rail section allowing you to mount a red dot, but it’s designed not to interfere with how that Sub 2K folds – which is kinda the point, right?

The STNGR Axiom 

STNGR is a fantastic rail company that has slowly spread into other realms. Their latest venture has been red dot optics.  I’ve been impressed with the Axiom optic, and it’s included both a low and high mount. With the low mount and the MCarbo scope mount, I can run the STNGR Axiom perfectly on my Sub 2K.

The Axiom is a compact red dot scope with a 2 MOA red dot with 11 brightness settings. The red dot becomes quite bright, and the two lowest settings are night-vision compatible. The Axiom is ultra-lightweight, and the optic is IPX7 rated for full water submersion. It’s an affordable option that’s quite robust, and I run a few STNGR rails, so I’m excited to see where to go with their optic’s line. 

A red dot on the Sub 2K makes it faster, easier to handle, and more accurate at range. The iron sights are ok, but an optic improves the weapon’s handling substantially. It’s easier to use in low light conditions, and with the optics mount, I’m not losing my ability to fold the gun. Married together, the MCarbo mount paired with the Axiom optic make excellent KelTec Sub 2000 accessories.

Gator Hide Bolt Tube Sleeve

It’s not actual alligator hide, by the way, but it’s effective. This is a comfort add-on; you’ll feel it once you get your cheek weld. Putting your face against that metal tube can be really hot or really cold, depending on weather conditions. Either option sucks. 

The Tandemkross bolt tube cover is a sleeve that goes over the 2k’s steel buffer tube. Not only does it mitigate heat or cold, but it also reduces vibration. Obviously, this makes things more comfy, but I’ve heard a few people say it helps mitigate that tremendous felt recoil of the 9mm cartridge. That could help with accuracy, follow-up shots, etc. 

Me, I’m not as worried about taming recoil as I am about the comfort aspect. I don’t get paid to embrace any suck anymore, and letting that bolt thump back and forth under my cheek gets old. 

Lookin' for Kel Tec Sub 2000 accessories for sale? The Gator Hide bolt tube sleeve should be one of your first searches.

Matador Arms Regulator 

The Regulator is an exciting device and an interesting addition to a 9mm carbine. It’s a muzzle brake that has the ability to completely tune or even close every port. The idea behind the Regulator is simple. You can run it wide open most of the time. This results in the Matador Regulator, reducing recoil and muzzle rise significantly. It eats through the nominal recoil generated by most 9mm rounds and does an excellent job of making a controllable Sub 2k even more controllable.

Let’s say you are shooting at night and want to reduce muzzle flash. Close up the Regulator and boom, no muzzle flash is generated through the ports. If you go to an indoor range and want to be a little more complete with your muzzle blast and noise? Close up the Regulator. The Matador Regulator is an outstanding muzzle device, and it comes in 5.56, 7.62, and of course, 9mm

Vickers One Sling 

It’s 2020 y’all we got a long gun which means we got a weapon that needs a sling. It is an essential among Keltec Sub 2000 accessories. The Sub 2K is an ultralight PCC, and when it comes to slings, I could only think of one that mattered, and that was the Vickers One Sling. This sling is one-inch wide and .25 inches thinner than most slings.

This reduced weight and bulk and are better suited for smaller guns. The Vickers One Sling is a standard Combat Applications sling, just a little skinnier than most. The One sling features the same unbeatable pull tab design that instantly changes the size of the sling with nothing more than a tug. This allows you to run the gun with maximum mobility or to tighten it down to use your hands without your weapon dropping and sliding around.

SUB2000 Aluminum Forend with Picatinny Rails

Yes, it’s a quad rail for the Sub-2k, and that’s handy. But. If you install this, you cannot lock the weapon into the folded position. That to us is plenty of reason not to get it, but there are undoubtedly some folks who have a good reason to sacrifice foldability for rail real estate. This is for you guys. Kel-Tec recommends this only for 1st gen Sub 2Ks, by the way. 

SUB-420: Aluminum Forend with space for up to FOUR Picatinny rails. This replaces your old SUB2000 forend with a high-quality, durable bi or quad rail. Recommended for the 1st gen Sub 2000 only.

Precision Match Aluminum Trigger & Trigger Guard Upgrade

This late addition comes from M-Carbo yet again. This is intended to replace the Sub 2K’s stock plastic trigger and eliminate “plastic flex.” You can get it with either a flat or a curved trigger (both longer and wider than the factory version) and add a trigger guard for the complete set. You’ll want to doublecheck your serial number against the manufacturer, as some Sub 2000s have a protrusion (solid chamber cartridge guide) on the barrel lug.

Performance Services Folding Rear Sight

This replacement rear sight is a folder (think BUIS). They’re aluminum and stainless steel, with a red anodized actuator level that can be mounted to either side of the weapon. When you look at their Amazon listing you’ll see it mentions Airsoft. That doesn’t seem to be a reason to avoid giving it a try. Performance Services LLC makes a variety of gun parts, and not just for the Kel Tec Sub 2000. 

Here’s the rundown per the manufacturer (I haven’t tried it myself). 

  • Larger .170″ sight aperture as compared to the .125″ original sight aperture.
  • Skeletonized, large tactical actuator lever available in either black or high visibility red can be mounted for right hand or left hand use.
  • Same height as the taller aperture rear sight available from the factory on the Kel Tec Sub 2000.
  • The first and best lever actuated folding rear sight for Kel Tec Sub 2000.
  • Will not interfere with the folding feature of the Sub 2000. 
  • Compatible with both the Generation 1 and Generation 2 models.
  • Simple drop in installation. Instructions and installation tools included.

Some Kel Tec Sub 2000 Upgrades for Ya

    Best upgrade is the Red Lion Precision rotating forarm. Versions for Sub9, Sub2k g1 and g2. Allows you to have rails on 3 sides and will rotate so the open side is up for folding.

  2. Mohsen Chavoshi

    very good information …

  3. PTS Terbaik Indonesia

    Are there any specific accessories designed for improving the Kel Tec Sub 2000’s reliability or addressing common issues?

  4. Rodney S Krueger

    Looking for Sub2000 accessories. Just checking out what you might carry for them

  5. Goge S Johl

    If you add up the cost of just 2 of the suggested upgrades it will cost more than I paid for my Sub 2K g2. Get back to reality.

  6. Richard Rotenberry

    I have the Kel Tec sub 2000 as pictured in your article. I bought it about 2 years ago, and it works perfect. I mounted a red/green dot scope and this is before I found your article. I do not follow the stock up, nor do I want to. I leave the firearm hanging on a knob with the sling as a quick response home weapon. I am pleased to find the MK 4 Stiener Light in your post as I have searched for a night light mount. Thank you.

  7. Jim

    Rail mounted laser will not hold zero on stock gen 2 gun.

  8. GomeznSA

    Interesting choices. My question is will any of them work on the early model Sub9 which of course evolved into the newer version.

  9. Steven D

    Of course there is….it looks like it has a whole rail in front of the optic platform the pic shows.

  10. kurt Mr betournay
