Everything it promised!

Love the Spring (and trigger) Great video too. Its delivered everything it promised!

Trigger is 1000 times better now

I paired the springs and steel trigger and it got rid of almost all of the slop. Feels so much more solid and sleek. I couldn’t ask for a better trigger upgrade. Thank you MCARBO. I hope to see more for the ksg and rdb


Easy Install

Watch the video, they provide, a couple of times and it's easy... the only difficulties I had were getting the sear to stay in position and then getting the pins to line up correctly when putting the two halves back together, but I think that was my error... two things I did a bit different is I used a heavy duty rubber band to hold the hammer in place instead of duct tape and that first spring they said to be careful to hold down when first taking the halves apart, or it will shoot out... I held it in place by putting thin punch, or strong piece of wire, down the center of the spring to hold it in place, so that it could shoot off.

Makes trigger pull what trigger pull should be! However--------

I have a suggestion that "you-all" might want to ad to the "Trigger Job" Video, which by the way quits before you put the action bar spring is put back in and the other half of the system's frame is put together.

When taking the frame apart the and the frame halves are separated slightly, take a piece of heavy polyester thread, stiff string, or preferably fishing line; and run down along the action bar through the spring and out the bottom of the frame and wrap around behind the frame half and tie the two ends of the string together snugly. This will retain the spring and keep it from flying away.

Then when reassembling; tie the action bar spring back in the same manner and put the frame halves back together. Cut the string at the frame's lower mating edges and pull it up and out towards the top of the action bar.

This is a very simple and necessary step to insure that spring does not get wings. I know from experience, because on reassembly, before I could get the frame halves together my spring developed wings!

My wife and I spent over an hour looking for the spring and I finally put the frame back together, because I was working on our table in our motorhome (We live in a motorhome) and she wanted to make supper. After supper, I continued the search and finally found the spring on the other side of the motorhome, on the counter top, behind the kitchen sink; Praise The Lord!

It was after I lost the spring, that The Lord gave me the idea of the spring string! I tried it and it works! I guess He was giving me another lesson in patience.

I thought I would share the idea with you and maybe even suggest that you include about a foot of stiff fishing line, or real heavy polyester thread, string in the trigger/spring kit. It's up to "you-all" now.

I also drilled a small hole in the trigger guard, lining up with the sear adjustment screw, of the new M Carbo Target trigger, to do a final tweak, which I have done to many of my guns. Anyway, I got it all together and it works Great. Verrrrrryyyy Satisfied!!!!!

AND REMEMBER: "It is better to have more Guns and Ammo than you need; than not to have the guns and ammo you need!" Others can pick up the gun and continue the fight when you are gone!


Best combo

This new trigger plus the spring kit really makes a huge improvement, literally cut the trigger pull weight in half and the aluminum trigger gives a smooth feel without the plastic mould lines of before.
