U.S. Special Operations are a remarkable, formidable fighting force who are admired and feared throughout the world. Now, the military’s elite warriors are set to become even more deadly with a new addition to their arsenal.

About $48 million-worth of new, cutting-edge suppressors will be in the hands of America’s top military personnel, enhancing their capabilities on the battlefield. For several years, Special Operations Command has been hunting for the best suppressed upper receivers for their M4A1 carbines.

They’ve chosen the Sig Sauer MCX SURG System to upgrade these weapons. The new Sig suppressor will deliver accuracy, speed and reliability. And of course, it will deliver outstanding sound reduction. The new suppressors are made of ultra-advanced materials.

Sig Sauer has a distinctive looking, revolutionary approach to suppressors. They look nothing like the suppressors you see in movies and TV shows – these rifle suppressors are tubeless. They’ve eliminated the outer tube typically seen with suppressors.

In addition to reducing weight, this tubeless design increases volume, lowering pressure and temperature for greater durability and leading signature reduction. One of the keys to this feat is the special “baffle” design.

Thank you. Link?

Interesting. A detachable suppressor on an SBR piston upper. In and of itself, nothing ground breaking.

I love Fox news' "ultra advanced materials". Um....likely stainless steel and titanium -- pretty new concepts for a suppressor. However, the exterior looks of the suppressor is interesting. An aramid-based mesh (oh gee, kinda what kevlar and nomex are?) is on the outside of the can. Allows cooling of the can's exterior, but offers some level of burn resistance to skin and fabrics. This may not do much for the mirage issues that most can covers are made for, but maybe mirage isn't an issue with units that will deploy with them.

It will be interesting to see what Sig did with the can's internals. I suspect an evolution of baffling and overall can structure, not a revolution.

Good for Sig -- I hope this works well for both Sig and our troops.

Thanks, fritz.

Does anyone know if this proposed conversion/upgrade kit works with a mil-spec trigger and if the bolt carrier group works the same as the post MCX recall/upgrade? My understanding is that a mil-spec trigger group would not work in a post-upgraded/recalled MCX. I am confused as to how this would work.
