Here is the original cheap plastic LCI. Besides being a product people who will never own a firearm, it has been known to cause jamming problems on an otherwise fine firearm.
Here is what the kit contains. I ordered the regular stainless. The instructions are on the obverse of the paper shown, but I wanted the contrast for the photo. Just simple text. You get the LCI filler, a set screw, an Allen key, and sandpaper (minor fitting may be required, but mine didn't require any). Expensive for what it is, but it is well executed and worth every penny IMHO.
When you take the gun apart you are left with needed to remove this pin (black dot in the picture). It is metallic and I used a magnet, plus working the LCI to pull it out enough until I could grab it with pliers.
See my Lego train magnet? Any suitably strong magnet will work; alternatively you could probably drill it out, but a magnet runs much less risk of damaging the firearm. I couldn't give one hoot about Ruger's LCI pin.
Once you have the old LIC out you just put the new filler in which it threaded for the included set screw. Simple. Reassemble and you get this:
I'm so happy having gotten rid of that cheap, plastic junk. In case you hadn't noticed, I hate the LCI on the MkIIIs. Next up, trigger disconnect. In case anyone is listening, I refuse to buy a SD gun with your silly internal locking mechanisms. Put them in there and you loose my money.
