KSG trigger kit

Ordering was painless, shipping was prompt and packaged well, installation was a snap (utilizing the YouTube videos), and product performed as described. OK, there is the watered down review. I cannot speek well enough about the products that MCarbo produces and makes available to us. The KSG trigger spring kit (and trigger...also installed at the same time), works wonderfully. The pre-travel is gone and the trigger break is crisp and half the factory trigger pull (just by feel, no gauge). I feel the combination of the two will allow me to have a better average this fall at deer camp during the skeet competition (yes, the KSG is a wonderfull clay busting gun). The looks I get when I use it are amazing!



Excellent kit. I’ve done my own trigger work for decades on a number of firearms. This one was the most challenging. If you do it yourself, watch the MCARBO video. It’s invaluable. Be patient. Do not force the lower receiver halves together. Keep working them and the pins will fall into place. Trigger and springs are a nice upgrade.

Great value - easy install

This is a terrific upgrade to a really fun and functional shitgun. Installation video is very well done and makes the install a breeze.
Highly recommended.

Trigger Spring Kit

If getting the TRIGGER you need to get the SPRING KIT!! Trigger and Spring Kit made a world of a difference. Video was easy to follow. I RECOMMEND BOTH TO ALL KSG OWNERS!!!.
4.5LB squeeze...less than 1/4" travel, then a crisp clean Break!!

Great product

Great reduction in trigger pull! I really suggest the product in bundle with the trigger replacement.
