Gen 1 trigger bundle

Slick and not too difficult to install. Of course I had to watch the videos on YouTube. After doing one install I feel doing a second will be a piece of cake. I also got the two finger charging handle, (my original broke). Trigger and springs make a huge difference but if cost is an issue get the springs first, trigger second and charging handle third. Of course the screw kit and aluminum trigger guard are sweet and make you sub feel more sturdy.

Very Nice Upgrade

Purchased the full kit after carefully reviewing each item individually and very glad I upgraded everything at the same time. The items in this package all perform as advertised and the trigger pull is crisp and clean. I have never taken a gun down to this level before and this firearm had just been purchased and upgraded from the Gen 1 model and never fired, so I was bit nervous doing all of this. I watched each video and had no issues with the upgrade and learned a lot in the process. Very weel done and definitely recommend this product.

simple value

Thank you MCarbo for offering this simple kit that smooths this rugged firearm's function. This is my second purchase of this kit, because the first made a significant difference with my 1st modified Gen 2. Now both of my Gen 2's feel and operate with ease. Thank you for all of the support and tremendous customer well as the innovation. I will continue to recommend your products to all of the Sub2k owners that I find.


Trigger replacement, springs, and metric bolts, no tigger guard

1st off, great communication and service.

Trigger job was dead easy (except for that detent). That's not the kit but gun design.

Video's were straightforward with one exception. I found it easier to set the short end of the trigger return spring 1st and then the long end.

The trigger itself is head and shoulders better than the stock one. The replacement springs and a little polishing gives the trigger a much better feel. Don't have a way to measure pull but subjectively it feels like a smoother and lighter.

Recommend this upgrade as the Sub2000 stock trigger is pretty bad.

When buying this you need to know it's not a complete trigger replacement though. The hammer and sear are still stock so still have the gritty creep issue. Polishing helped but this will never be a match trigger, but does not need to be. Have only shot this out to 50 yds so far but it's pretty accurate with a red dot.

Looking forward to seeing your aftermarket red dot mount.

S2K gen2 trigger kit

Hi Chris,

Yes, thanks I did receive my parts from you guys very quickly. Even though it was said they were on back order. They were still received within 5 days of ordering. I watched the installation video once before attempting to break the the gun down. Then played it while I was installing the trigger kit in my sub2000. The whole thing went flawlessly. I've already been referring friends to you guys for their upgrades.

Thanks a lot and keep up the good work brother,
