Consolidation of Trigger Group Installation INFO: A suggested reading list for first time S2K trigger installers

I have resently seen a number of new members coming into this forum that are installing some of the great mods from MCARBO. I thought I would try to make it easier for them to enjoy the experience a little faster.

There is a bunch of info on this forum that is spread out over a vast range of topics that are closely related to the workings of the S2K pistol grip inners.

While the MCARBO videos are great resource the brotherhood has contributed much information beyond those install videos.
I will start this subject and try to keep it pure info. I will be adding what IMO are the top videos and subjects that may be able to help the NEW BROTHERS in pursuing the pleasures of the S2K experience.
Please feel invited to add to this collection.
Please start at the top of these threads to get the full impact of how much work BROTHERS have done to help us all.

@russ thanks for the KUDOs. I think I mentioned above I might add to this thread.
I did some research and found a post I did back in April '18 in a thread Top Secret M*CARBO R&D on the refinements to the charging bolt/charging bolt spring/bolt/hammer interface to smooth out the action as the assembly cycles.
As that assembly needs to be removed to do the work on installing interior upgrades I thought it would be appropriate to link it here.

Here is something else that drove me nuts. As everyone that is here knows the smoother the action the less muzzle movement. If you have everything smoothed out inside consider this. Start by making sure gun is safe and UNLOADED. Do everything to remove charging spring leaving charging handle in. If…
