The US Government just announced its intent to award Sig Sauer the SOCOM PDW contract for their MCX Rattler line of firearms. This includes both 5.56mm and .300 Blackout variants of the gun as well as their SL series of suppressors and other accessories such as cleaning kits, magazines, and caliber exchange kits (the barrel assemblies to convert between 5.56mm and .300 BLK). These guns have been proven to be reliable guns on the commercial market and are now making their way to the military. It's also not surprising since SIG has won contracts for other MCX variants and SL suppressors so it was likely a downhill battle for SIG to compete on this contract, but then there's this:
From the government's release "Except for Sig Sauer, the vendors did not meet the technical requirements and/or the weapons do not meet the commercial definition. Due to the nature of this particular effort, USSOCOM cannot procure PDWs that are prototypes, under development, not in production, are in limited production or will be in general production in 1-2 years from now (assuming the PDW is not in production or is in limited production)."Essentially no other company submitted a commercial product that was in full production and other submissions didn't meet all of the qualifications. It's hard to say what limited production means in terms of quantity or units produced because there's certainly some other good PDWs out there, but nobody at SIG will be arguging about it.
With the likely release of MCX Spear rifles on the commercial side, perhaps we will see a MCX Spear Rattler in the near future. Only time will tell, but SIG is certainly killing it (pun intended) with these military contracts.
