The Virtus was debuted in 2017 I believe which leaves us 3 years overdue for a replacement product given sig’s usual pace of replacing SKU’s. It appears that a next gen Sig MCX was teased on Instagram during a Sig suppressor shoot. No details were given but the rifle appears to have slimmer handguards that now have a threaded screw for retention on the shoulders like the SPEAR. The gas value also appears to be slightly different. There are also a few updates to to the upper with a few more venting holes cut on it and it appears that some angles are cut differently forward of the ejection port. The lower appears unchanged.

Here is the video:
“Gen 3” MCX

I personally like the improvements including the lack of the large holes on the handguard to adjust the gas piston. Gonna need to get in line when they become open for orders. Please make them available in Black.
