"SIG SAUER has just announced the commercial sale of the MCX-SPEAR in .277 SIG FURY. This is a very cool opportunity. Aside from full-auto capability, you’re able to buy the very same rifle currently being offered to the US Army, and the Army should make its decision soon on a new suite of weapons to replace the M4 Carbine and M249 Squad Automatic Weapons currently used by its close combat forces."
