I had the brethren at MCARBO install this trigger on my new KSG as well as the aluminum followers, trigger spring kit, shell deflector, QD sling post and they removed a lock tited grab rail as well as the locktited QD post that I had installed and could not rremove, I also had the 30 minute polish work done in it. To say it is not the same shotgun is an understatement to put it plainly. The original KSG is a fine shotgun, so without insulting their good work I can say my shotgun has been uprgraded in ways that only the MCARBO CNC parts can do, IMHO. The pump action is smooth and snappy, the magazine feed is smooth and makes the weapon smoother and quicker for me. The trigger kit, well it is not the same weapon. The original factory pull and let off was a bit plastic feeling and heavier. I haven’t, measured the pull, but the feel is not too light, but is a lighter, cleaner, solid, snappy let off thing, now. As subjective as I am reviewing my shotgun I am quite pleased with the MCARBO parts AND the MCARBO install, it was worth the wait for sure.
