M*CARBO $30 KelTec SUB2000 Trigger Job (and Target Trigger)

In this episode of TFBTV, James installs and tests M*CARBO’s $30 KelTec SUB2000 trigger kit, which is advertised to reduce trigger pull in the SUB2000 by about 3 pounds.  While installing the trigger spring kit, James also takes the opportunity to install M*CARBO’s $30 aluminum target trigger before taking it to the range. M*CARBO is veteran owned and donates 5% of sales to charity, and also has installation videos on their site.

    Looks like a nice upgrade to the Keltec. I must say though, that every time I see someone doing gunsmithing with a big carpenter’s claw hammer, it makes me cringe!

    • Dougscamo

      From the looks of the hammer, James bought it for this project…..should have bought a shop hammer….

      • James Reeves

        No, I just take very good care of my tools by not using them. It’s for the best.

        • Dougscamo

          Though Iksnilol might enjoy watching you sweat through this 1 1/2 hour job….I think you are right….

          • iksnilol

            Honestly, I don’t think he could do it.

            I hate to admit it, but just look at his dainty, clean and slick city hands. Best work those could feasibly do is a pedicure.

          • Dougscamo

            Guess that is the reason for the F-bombs….plus….by his own admission….all he hunts is a parking space….shudders….

          • iksnilol

            I am sickened to be honest. It’s like a Jeep with no mud on it.

          • Anonymoose

            My Jeep has snow on it. It’s not warm enough for mud right now.

  • Don Ward

    Kel Tec. Not even once.

    • gunsandrockets

      Watching that disassembly doesn’t inspire confidence in quality of the Sub-2000.

  • Dougscamo

    “after we have cosmetically ruined our KelTec Sub 2000″….isn’t that a contradiction in terms when you say KelTec and ruined cosmetics in the same sentence?….

  • Joe

    Nice. I’m looking forward to a binary trigger someday. Just sayin.

  • VF 1777

    James! Thanks for doing the video man! I think I finally got up the motivation (and guts) to sit down this weekend and install mine now (which I’ve actually had for a couple months now… yeah, I know…) Hey – if James can do it, I can do it – right? hahaha

    Oh and dude – you of course should’ve used a band-wrench for the castle nut 🙂 (notably the only reason I actually have one myself is from working on my Gen1 Sub2K though – doh)

    Anyway, thanks bud. You are el hombre. Peace

    • JLR84

      Don’t feel bad. I’ve had mine since September, still haven’t installed it. Maybe I’ll do it this weekend.

    • James Reeves

      No problem! And, yes, this shows that if *I* can do it, you definitely can. Get back on here and let me know what you think after the install.

      • A.WChuck

        I used a brass punch, but a polymer one would work as well without damaging the cosmetics of the rifle.

  • Herschel Walker

    No, just no, LOL.

  • SP mclaughlin

    I’m gald James pronounced their name.
    Sounds like some Major league gaming clan.

  • ontheleftcoast

    James, I think you missed the obligatory safety warning: “Wear eye protection anytime you’re within 10 feet of a firearm.” I could almost feel that spring hit my eye.
    Thank you for the most honest and realistic install video – ever!

  • Lostcoast

    Nice review James! However at the end of your video you speak of this being a “$30 upgrade” when in fact it is $60 for the Carbo trigger and trigger spring, yes?

    • James Reeves

      Thanks! The trigger is basically a cosmetic/minimal utility upgrade and has nothing to do with the trigger job itself. The factory KT trigger is plastic, but you can replace it with an aluminum trigger for an extra $30. I figured I’d go ahead and do that since I had the gun apart.

  • A.WChuck

    I installed this spring kit a while back and it improved the feel and lowered my Keltec’s 11+ pound pull to around 8 pounds. Yeah, I got a lemon and failed to send it back to Keltec. I needed to buy a new trigger bar, or whatever it’s called as well.
    I really wish Keltec would license their designs to Ruger or anyone else.

    • Jr Dirty

      Same here. There designs are ‘revolutionary’, the RDB and KSG are fantastic designs/concepts in principle, but everything they make feels like a pre-pre-production prototype. Would love to see a ‘proper’ manufacturer fab these designs. The RDB is probably the best designed bullpup ever made so far.

  • Paul O.

    Took a trigger pull guage to my Gen 2 and it was 4lbs. Honest. Maybe I lucked out but I’ll take it. Disassembly looks a bit painful.
