 Attached FileA roughly three (ish) year project is basically done. It is a Colt SCAR-L Type B prototype clone. I have sent an email to A.R.M.S. to see about getting three replacement nuts for the top rail. They are not supposed to be colored as shown in Chris Bartocci's photos below.  Attached FileAdditionally, after trading for the Elcan that I have, I realize that I need a generation 1 Elcan Specter. Mine is generation 2 or 3. So, I will look for a good generation 1 Elcan in 2024.  Attached FileSpecial thanks to @aeyoung for loaning me the Executive Summary document and the SCAR-L Type B operators manual for what has probably been close to a year. His two documents helped solve some of the remaining mystery. Special Thanks to Christopher Bartocci for being the only person to capture and publish any of the history on the Colt SCAR-L Type A, B and C prototypes in his excellent Small Arms Review articles. I also give thanks to a couple of anonymous people who helped me out. |

This is a very cool project that I am sure took a lot of time and research to get accomplished.
I have a few questions/comments. - When doing the research, was there any clear views of what the submitted rifles had for rollmarks. Here is a screen shot of what was in the manual in the video.  - That 90 degree 3 position selector is pretty neat but looks like it would be awkward to use. I maybe missing something but it seems like lever should be facing the other way. Was this lever also ambidextrous on the submitted rifles. - The A2 forward grip looks kind of out of place. Seems like it would fit in perfectly in a GD thread of “Beers, Dremels, and gunsmithing”  - I’m surprised that the coating matched the anodizing on the other upper so well. I wonder how much variation of color Colt gave the anodizers on that color. None the less, great job on the project. |

Here is a photo of page 452 in Vickers Guide AR-15 Volume 2, Second Edition which shows the selector configuration on the SCAR-L Type C prototype.

No other magwell markings |

How difficult was it to source the ARMS handguard?
I’m partial to the type A myself but this type B you got going on is SICK. |

The handguard is just about unobtainable. I got lucky because someone reached out to me and offered to sell it to me. Supposedly only 7 to 10 made it into commercial distribution. I have one, a fellow collector has one, and I have seen one other sell on Ebay about a year ago. |

Did you ever get replacement screw nuts from ARMS to replace the ones that accidentally got cerakoted?

Very cool.
When searching for an Elcan, search for SU-230. Likely what you are looking for. |
