Excellent, high quality, upgrades

Bought Sub2K- neat but meh...
Bought Mcarbos upgrades- a different gun!
The install on the Bundle was not difficult at all. Just follow along with the video. The most difficult part was the safety detent and spring...kept shooting them off my work bench!
If you have a S2K and have not bought the upgrades...stop farting around and do it. You will not be disappointed!


Pro trigger kit

Worth buying the complete kit!! Easy to install when using mcarbo’s helpful videos and some standard tools. I was a little concerned about tackling this project but with the help of the videos I was able to complete this project in about an hour from the comfort of home! I have purchased basically every part offered for my 9mm sub2000 and let me tell you. It’s like having a different gun!! Glad I found this company and glad to be apart of the brotherhood! *Side note make sure to polish the stainless feed ramp.. money well spent! Can’t wait to see what they come out with next!!


M Series upgrade

I completely upgraded my Sub-2000 to an M-series plus. Everything works perfect, as I followed the install videos. I found a few ways to improve the install: Put the grips back together with the trigger parts without Locktite and when I was finished and sure everything was working I put the locktite on the screws one at a time, so everything stayed together. Also putting on the buttstock, if you can secure the two parts together, as I did, then drill the holes the same size as the internal part of the add on and drill them out to 1/4", it fits perfect, it leaves no marks on the original buttstock.

You Can Do It!

First off, I am NOT a gunsmith. The last time I opened up a firearm I ended up bringing it in pieces to my gunsmith. So I was naturally hesitant to take on this project.

Since I had already done a few smaller M*CARBO upgrades (rear sight, muzzle break, recoilless charging handle) and had already watched numerous M*CARBO produced How-To videos, and since bringing the carbine in tiny pieces to my gunsmith was always an option; I decided to try.

I had some difficulty of course. I had to start over once and backtrack maybe four times. The most difficult part was getting the hammer to set back.

Not sure what I did wrong but when it went it went easy.

I was not confident enough in my abilities to apply Loc Tite to all the assembly screws from the outset. Instead I waited until everything was together and then carefully backed out each screw and applied the Loc Tite one at a time.

Besides the awesome trigger parts, I think the most important upgrade is the stainless steel feed ramp.

My carbine is fairly new (6 weeks) and had about 600-700 rounds through it prior to this upgrade with zero malfunctions.

During the install I was able to confirm that the OEM plastic feed ramp was indeed already damaged. One tip had broken off.

I don’t have a tool to measure trigger pull before and after, but the difference is immediately noticeable.

I have not fired it yet as the Loc Tite needs to set up but all functions checks are good.

Just take your time and pause/rewind Chris’s excellent video as needed and your efforts will be rewarded. Don’t skip the polishing part. If you don’t have a Dremmel tool this is an excellent excuse to get one.


Worth Every Penny

Installed this kit on my sub. Lowered the trigger pull fro 9+ pounds to 4 pounds. Took it to the range today and it performed flawlessly. Thank you Mcarb for the two hour long video on this install, made it very simple to do the install
