I received this Email today from Sig. Looks like they're introducing the civilian version of the SPEAR platform. The video within describes how they took features of the original MCX and Virtus platforms incorporating them into the SPEAR-LT models, of which there are a few including one now chambered in 7.62x39.
Here's a link to the video only (duration 6:44)
