I was searching for that but I must have overlooked it as I was thinking that was the next step.

Thanks!

I’ve been on the road for a few weeks and had a stack of gun parts awaiting me when I returned home.
Among those were M*Carbo Recoilless Charging Handle and Recoil Buffer, and the p226 catch kit from Kel-Tec.
It sucks having one 10 round Beretta mag to use. I have several p226, 15 and 20 round mags.
Just installed all this morning, except the new locking pin. I tried, but had to walk away from it for a bit.
I watched the video and followed Chris’ directions, but still can’t get it to line up and drop in.

I was also playing around with a AR-15 flash hider that I removed from my AR, looks cool on my sub.
It’s just for fun and looks until I get the muzzle brake from MCarbo. That’s my next purchase.
Along with the M
Carbo bolt sleeve cover and maybe the heavy bolt from Kel-Tec.
I’m wanting the trigger bundle as well, and I think that will be all for a while.

One other item I had waiting here at home was a cool looking buttstock that I thought about modding to my sub.
I don’t have it figured out yet, but I really haven’t put much time and thought into it.

Installed Midwest Industries’ Gen2 SUB 2000 Mini Picatinny Rail Optic Mount. Had to do some trimming on the M*CARBO Bolt Tube Cover because of a clearance issue while folding gun to storage position.

I’ve posted the progress of installing the buttstock I mentioned above, in this thread.

It’s going quite well, I can get on the sights, and it feels pretty good on my cheek.
I’ll post here when it’s done and all the MCarbo parts are ordered and installed.

Been looking at those on Blitzkrieg, how do you like the triangle? And do you run the MCarbo rear peep sight or original?

I forgot about this post. I got all MCarbo parts installed and tested.
Except the new buttstock pad and the tube cover, both ordered and shipped.
I’ve also bought and installed new furniture, black, with the compact forend.
I’m still toying around with the original furniture and the butstock mod.
I ordered the gen 2 black forend from KT, as well, just to have on hand.

Love my S2k, and all the MCarbo upgrades.

Well, it’s the 15th of April and taxes done and filed with monies sent out. Now, treated myself to some S2K upgrades with a recoiless charging handle ; recoil buffer ; tube cover; and the newly released MCARBo Buttpad …in my favorite color of course , Scary Black! Had to get 1K rds of 9mm and 223 for testing this spring. Because the Best things in Life are, …Girls, Guns and trucks that all run fast! :vertical_traffic_light:

Update after install and range test:
Hey, Brothers in arms…installed the new buttstock pad , recil buffer pad, recoiless charging handle, and bolt tube cover…after 250 rds , the mods make a differance in both comfort and general sight on target recovery. I Find it funny that sevaral small changes make a big impact !
Oh , went and ordered another 1000 more rds for S2K breaking in period. My scary Black polymer ( no name yet) , loves the mods as much as I enjoy throwing lead down range!

Added buttstock, muzzle brake, trigger springs, trigger guard, recoilless charging handle, recoil buffer, and new steel screws and pins. Added a red dot too and it looks fantastic. Totally different feel (soft, no other way to express it) and was truly loving it until I noticed cracks in my sub2 yesterday while cleaning her up after pushing through a few hundred rounds. Totally bummed as i just added all of the upgrades this past week so really didn’t get to use it much or for long. Emailed kel-tec and hoping their warranty is as good as others say. Will keep u all posted as to how this ends up.

Trigger bar and trigger springs, buffer, removed stock sights added laser sight and red dot sight . Just purchased muzzle break.
I could not tell if the recoil buffer did anything.

I saw the new optic mount at the MCARBO store and it is pure, true, and solid. I plan to buy one

All the parts have been well thought out And much needed!!!
With that being said, my favorite part purchase so far has been muzzle break. Makes the firearm li mean and adds better muzzle control. Getting ready to purchase trigger package so im sure my answer will change lol… carry on brothers…

@Irish Welcome to the forum. Look forward to hearing back when you do the trigger pack.

@Irish Welcome to the forum Shaun, it will get tougher to pick your favorite MCARBO part once the other upgrades are installed.

Just added a Bushnell Haste to my 2nd Sub ( a nickel boron) which has also been completely MCarbo’d out. The Haste is a red laser forearm grip. At 25 yards in doors it is a a single hole punching tool. A great addition to any sub. If you like lasers you will really like how this preforms and still allows for folding.

I recently ordered two Sub 2000’s. I have completed (as of yesterday evening) both complete trigger upgrades with the aluminum trigger guard and notch rear sights on both. Also, I just ordered (a few days ago) two butt pads to install as well. Everything is installed now. I ordered some 31 round .40 magazines and am ready to go test these out and here in Phoenix, there is inclement weather today. So, I will put off testing them out until a nice sunny day. I noticed several things to pass along to those that might be installing these kits. First-of-all, that pesky retainer ring on both sides of the safety can fly like a bird. So, I used a clean washcloth placed over the safety leaving just enough room to get in there and remove the ring. The armorer’s wrench has a slanted end and makes it difficult to loosen the ring so I used a pair of needlenose pliers to loosen them and then grabbed them when the ring shows a gap on the other side (indicating it is loosened). Be extra careful when it is in that position since it can fly off easily.
Meanwhile, I installed the flat triggers on both sub 2000’s and I noticed a difference when they are installed. I don’t have a trigger pull gauge but can tell a distinct difference. So, I am ready to go shoot. Have about 500 rounds ready to go testing. I have not fired either one yet. That is around the corner when the weather decides to improve. In the meantime, I am doing a little research around the optical sight possibilities. I am looking at the Rodeo 5 Sig Sauer as a possible red dot optic and of course the new Mcarbo mounts. When, Mcarbo releases these for sale, I am going to purchase two so that I can retrofit both weapons and get them ready for trying the optic options. Meanwhile, I am gearing up for the testing which I plan to do with the new rear notch sights (which I sighted in tentatively with a laser bore sighter). I will log in and give feedback soon. By the way, the video for the trigger installation kit is a very good one. Congratulations on a precise and effective video. So, you will hear more from me soon. Thanks Mcarbo for providing so many and well made products for the Sub 2000 weapon from Kel Tec. BTW, both I have are .40 S&W caliber weapons. I picked them for the extra 100 foot pounds of energy (approximately) over the 9 MM. I have both calibers in my collection so no problem for me. Keep the faith and talk soon.
