US SOF tests SIG Sauer's MCX Rattler

USSOCOM recently acquired ten Conversion Kits from Sig Sauer. These kits will be used to test how well MCX Rattler systems function, as there has been a long-standing need for a compact rifle that can fire both .300 Blackout and 5.56×45 millimeter ammunition. It is also interesting to note that the kits will be delivered to the U.S. Navy Naval Surface Warfare Center in Crane Indiana, a facility known for ensuring that new weapons end up with SEAL units – in this specific case, probably DEVGRU.
