        Q. Can I order a .40cal instead of a 9mm M-Series?

        A. No, we are no longer offering a .40cal option.

        Q. Does a Glock 17 magazine fit a Glock 19 frame?

        Q. How many Magazines come with the M-Series?

        A. 1, and it holds 10-rounds

        Q. Why does a Multi-Mag cost $20.00 more? What is it compatible with?

        A. The Multi-Mag Base is a universal magazine release in that it allows you the option of changing out steel mag catches. ( Smith & Wesson M&P Mags, Sig Sauer P226 Mags, Beretta 92 & 96 Mags, CZ 75 Mags, S&W 59 Mags, CANiK TP9 Mags.)

          I recently purchased a KEL-TEC SUB 2000 online, and while looking for accessories, I happened upon the M*CARBO website. I discovered I could get all the accessories I wanted for a lot less money by purchasing a SUB 2000 Gen 2 M-SERIES, so I did. I was able to compare the M-SERIES side-by-side with a stock Gen 2, and I loved all of the improvements. My only problem is that now a have a stock SUB 2000 to sell!

          Great KT Sub 2000 M Series - great service

          I ordered the Key-Tec SUB 2000 M series. The upgrade work was done by M*CARBO- very fast service and great follow-up. I added some additional items to the M Series and the Videos made the installation easy and trouble free. I highly recommend M*CARBO.

          Did not think anything could be more fun than my CMR-30

          review-star review-star review-star review-star review-star
          Got my SUB-2000 M-Series Glock 19 model a couple of days ago. I used a Laser bullet bore sight to center it and took it to my brother in-laws place to shoot along with my CMR-30 (All the MCARBO Upgrades). Put about 100 rounds through it and can not believe how accurate it was. Then we attached a cheep Red/Green Dot on a riser to the rail and we put another 200 rounds through it and had so much fun I am now planning on getting the Optic Mount and a better Red Dot. The only issue that I had was when I tried to use some FEDERAL SYNTECH 150 grain, they do not seem to have enough power for the blowback. They work fine in my Taurus G3c so not a big deal.

          Now thanks to you I have a dilemma, I can not decide which one I like more. CMR-30 with all the Upgrades on the SUB-2000 M-Series.

          Cant say it enough, This Gun is F-ing AWSOME!!!

          WOW, that's the first word that comes out of my mouth, I mean what can I say, MCarbo got this right.

          I'm almost certain to use MCarbo for any additional upgrade items I may wish to obtain. Overall, the staff are professional and pleasant, and they produce extremely high quality products, I highly recommend MCarbo, their my family now.

          Can I save a little money by not getting any engraving in the M-Carbo install?

          Hi Patrick! That is a good question! All of our M*Series comes standard with laser engraving and is not a removable/discountable option.

          So the modified Sub 2000 to a M-Series costs $794.95 right? So if I want to include the Extra Operator Package too, what would the total be?

          Hi Steve! The Operator Add On is an additional $265. Once you select the configurations from the drop-down menu with everything you want, it will auto-populate an updated price for you!

          I'm a lefthander; does the extended mag release cause problems for lefthanders?

          Hi Ron! The extended magazine release could be problematic for lefthanders to be completely honest. At this time, the Sub 2000 is not ambidextrous.

          Good Morning Brother, at the moment the only color we have and plan on having for now is black. If that ever changes we will be sure to send out a message!

          I recently purchased a Sub 2000 with the Multi-Mag option and it came with a Glock 19 magazine. While searching for additional mags I see Glock now offers something called a Gen5 Glock 19 mag. Will this Gen5 mag fit my Sub 2000?

          Hey Brother, Gen 5 Glock mags will work with zero issues. Have fun!
