I think I'm doing it. I've always loved the Sig 556 design, but as you're probably aware, Sig USA fucked it all up and it became a hot mess and a pile of shit. I posted here previously about my Sig 556Xi hard stopping out of the box. Sig did fix it, but it was a perfect example of their new mantra of low cost over high quality.

JDI Firearms, however, is able to import the authentic Swiss rifles and I think I'm going to go for it. https://www.sanswissarms.com

The 553 is build to order, and they're sending me a build sheet tomorrow. From what I understand, you can choose American style magazine receivers or swiss style (requiring the swiss mags), multiple colors, and barrels of 8.9, 10.7, or 13.6.

I'm hoping they can build one as a rifle vs a pistol. If not, I'll just have to SBR the pistol.
