I was approached about this XM3 stuff by an old friend who used to manage the Remington Custom Shop down the street from us. He brought me one of his personal EFR mounts to look at and possibly reproduce. If I understood him correctly, the story goes that Iron Brigade was originally tasked with much of this stuff. They subcontracted to a shop called Colorado Micro Precision to make the mounts. That business is no longer around, and the part basically died there. I've been told somewhere around 50-55 of these things were made so it's a pretty rare part.
Until now.
The photos show the artifact piece and my SW assembly model. My understanding is there are two versions of this mount. The difference is how the lugs were spaced on the STENAG rail. The one I have modeled is the "original" design. The original looks to be finished by AO (aluminum Oxide) blast finishing followed by Type III black ano. That is no problem for us.
If folks are interested, we'll do a run of these things. I've seen Gunbroker auctions where this part and a scope rail have sold for as much as $750.00. (shown here: https://www.gunbroker.com/item/978812555)
$350.00 is where we'll start. If we get a pile of folks on board, I'll review this, and mold this into something like a group buy. If it goes that far, I'll move the offer to the GB section.
