Most people are against these. However, truth me told, they are decent little guns. Mine in .40S&W with Glock mags has taken four deer 🦌 in the last two years. They all were hit in the lungs and expired fairly quickly. This is a decent survival gun.

I recently got a Sub2000 in 9mm multi mag, used my armory skills to install all the MCARBO upgrades. HUGE improvement. MCARBO has a video that is step by step to get it all done. PATIENCE required, but I have accomplished the complete teardown/rebuild twice successfully. It has made the carbine a much better unit. I polished the stainless steel feed ramp/upper ramp and the hammer face, sear, chamfered the bolt to engage the hammer smoother (which enhanced the recoil speed also. smoother is faster). The MCARBO trigger (flat face), springs, trigger guard, trigger bar .. the whole kit, came with armorers tool and wooden dowel. GREAT range "toy" and as accurate as the shooter. Nice video by the way.

I've had the MCARBO fully upgraded version for about three years and love it. You focused a lot on their optic mount, but I don't care for it as I don't like how much it sticks out when you fold the gun. It makes it bulky which kind of defeats the main feature of the gun and is more likely to snag when pulling the folded gun out of a backpack. I initially went with another brands mount, but have since gone to a simple 45 degree offset mount. No twisting or flipping. The red dot is snugged right up to the gun and doesn't interfere with folding. It might seem weird to cock the gun over to shoot it, but it feels very natural and is easier and more comfortable to sight because since the gun is cocked over It means I have to cock my head over less. The trigger kit might be a bear to install, but most of the MCARBO upgrades your average gun owner can do. Most of MCARBO's upgrades are phenomenal with the exception of that optic mount and their buttstock pad (that you didn't mention). I'm not screwing holes in my gun to mount a hard pad. I went with the Missouri Tactical pad. Nice video, but could have been more detailed. Talk about the optic mount and how difficult upgrades are to install and then mention a couple of upgrades. Too bad you didn't mention more of them and what their benefits are.

The integrally suppressed version with all those upgrades would be bad ass!

Cool vid! I have two builds fully loaded w MCARBO gear on G19 and G17 and they are just plain cool kits, functional, light, easy to move and shoot etc etc. And fun to shoot happy sticks and drums too so unique looking too! Shout out to the great guys and vets of MCARBO! ❤

Dear Keltec, Partner with MCARBO and offer these from the factory.

"But, if you for example try to engage someone with a LVPO AR-15, you're guaranteed to get folded like an Omelette " - Brandon Herrera Gripes aside, I do like my S2K

I think anyone familiar with both companies' products can't help but develop a nagging feeling - that Kel-Tec and M*CARBO should merge. Kel-Tec dudes can keep coming up with ideas and designs and M*CARBO dudes can advise on material selection and be in charge of production and QC. I understand that when you invent cool nifty designs, your mind might not be too interested by the boring stuff, like implementation. But long-term, I think buyers would appreciate it 🙃 Seems like the concept of a folding PCC is here to stay, other companies are picking up the baton and running with it, arguably doing it better. You can't win on price point alone. A Gen 3 might sound exciting and mysterious, but maybe a solid, sturdy Gen 2.2 with better stock sights, some other improved parts, recoil buffer, etc. would be a good way to go. Just thinking out loud :)

I have a kel-tec sub2000 with many of the MCarbo upgrades. They have given me much more peace of mind. I dont like all the plastic. So i got all the aluminum upgrades, trigger components, red dot mount, etc.

I call my Sub2000 my "Transformers gun" since you have to transform it from storage mode to combat mode, I've added the Mcarbo sight mount, an Autobot badge, and plan to get a folding grip solely to add to the Transformers referemce

I wonder if by the time you buy all these upgrades and pay a gunsmith to install them you might as well purchase a Smith & Wesson FPC. I own sub 2000's in 9mm and 40 and have enjoyed shooting them over the years that I've owned them. I really like the FPC because of the ease of optic mounting..

Or you can buy all this already installed directly from MCARBO for about $1050. If you leave off the optic mount it's about $800. I'd recommend that and just get it and DIY.

They do not give the rebate they promise.

I wish he had a list of the products he used for the upgrades

The pin bit that the charging handle is attached to could be replaced with one that's offset at an angle so that it's away from the face. A tiny groove could be cut into that tube to help with that idea.

Good review but I have a question or two. I was a going to purchase one of these 9mm carbines but. the "loading lever' to insert a bullet. into the chamber kept pinching my finger. And it was very hard to pull back..... Did you replace yours....?

I am looking at the MCARBO rear sight replacement. My front sight is all the way down and I am still shooting low. I filled in the factory rear sight and drilled a new hole higher up. If that does not work the MCARBO taller rear sight will be ordered. I need the peep sight for quick response. Currently I am using a quick release on my optic. Return to zero is very good. I tried the 45 degree offset but can't get the height right. I too don't want the side bulk of the MCARBO mount.

Why doesn’t anybody address the charge spring tension. Am I the only person with an overly strong spring?

It is polishing a turd. Just a nicer turd than some of the other turds you could be polishing.

Skip the side mount optics, get a Red Lion Precision Gen 2 forearm. This with the other Mcarbo parts is perfect

Why not just get a gen 3 then you dont have to worry about a special mount for a red dot

Thats like the DJ Qualls of guns.

Or just buy a full mcarbo 2000 upgraded sub2000. I paid 1100 for my sub2000 with a addional lifetime warranty from mcarbo. Takes the sun2000 from being like tuffer wear from keltech to something major. I would say the keltech sub2000 from keltech is like buying a ford festiva. But the mcarb I makes you feel you just upgraded to a Mercedes. I have a cmmg banshee and I would rate my mcarbo right with it.

Please tell me what brand of red dot you're running on that S2K! I've got a .40 cal version that runs S&W mags to match my service pistol and I'm in the market for something smaller or more compact than the Sig Sauer Romeo5. Looks like you might also be using some custom earplugs too.

I love mine , I don’t shot it enough

More$ in parts than the firearm. Lol.

Sub is a great gun i hear

is that vertical foregrip legal in california? am worried about it being a felony in california

What vertical locking grip is that ? Thanks Jerry

Am I able to own this at 19 in Oregon?

Or... Just buy the S&W.

What holosun did you use?

what Holosun are you running on this ?

Thanks for telling it like it is. Get a fun smith to do the work. Im just like you .this would be too complicated for me. I would loose parts dor sure. All the shills on the net push this as ez to do.

does anybody know if mcarbo ships to canada?

Just shoot it stock. These ridiculously priced "upgrades" from a vet company is nuts. Save your money. Just buy an AR if you want a robust rifle.

Can someone tell me What optic is that?

日本だと､エアガンとしてもリリースされない隠れた銘銃！！！

Лайк!

I ju#t got one in 40 the only complaint I have is the peephole

There’s only one method of upgrade for a keltec product….. sawzall. Garbage.
