    MCarbo installation/gunsmithing

    I’m probably not alone when I say the the sub 2000 is one difficult gun to work on. Though I’m not a gunsmith, I’m not a newbie when it comes to upgrading or assembling AR’s. I bought the whole upgrade package for my Sub 2000 (springs, trigger, steel feed ramp, etc,) and, long story short, common sense finally prevailed over frustration and I bagged up all the bits and pieces along with my anxiety and sent it and the gun to the MCarbo guys for installation.
    I don’t know how they did it, but that pile of parts came back in record time as the beautiful precision 2000 I always wanted!
    The price of that complete, perfect install was so surprising low, I thought it was an error! They even applied a grip wrap for free, probably as a participation award.
    MCarbo is everything a supplier and gun company should be and more. I salute their honesty and competence and more so, their service to our county.

    Like butta

    Install was easy peasy, followed the video guide. Trigger pull is down to 3 pound from 9. Shoots great, was accurate before but now with less trigger pull i feel the difference. Looking forward to the next mods on my list!

    KEL-TEC SUB-2000 All In One Pro Performance Trigger Job Bundle

    Noce parts and flex is gone. Honestly didnt feel much difference in trigger pull/reset. But trigger and trigger guard lever are of good quality. Will continue to enjoy shooting and is awesome for packing throught the mountains.

    Not hard to do

    I bought this kit and was originally going to take it right to my gunsmith for the install. I watched the install video Chris put together and it walked me through it step by step. In fact I did it 4 times due to various blunders like forgetting to put the barrel back on the first time, forgetting a handle pin the second time and so on. But it was good practice tearing down and putting it back together. All in all it is a moderately complex job but when watching the video and going along step by step it is very doable for the average Joe.

    Not too bad

    Like the parts, all quality stuff. Shipping was a little slower than average but still didn't take long to get the stuff.
