You saw it here first! I had no idea that Sig Sauer were making AR-15 / M16 rifles but my DSEi spy spotted this prototype SIG516 1 PDW at the DSEi 09 expo. It features a 7″ barrel, putting it firmly in the PDW class, and chambers the 5.56mm NATO.
UPDATE: jcmiller points out that the lower receiver is semi-automatic. A production PDW would have to be fully automatic. Maybe Sig are thinking of civilian sales.
The SIG516 Tactical Rifle line has three different models:
- SIG516 PDW : 7″ barrel. A personal defense weapon (pictured above).
- SIG516 CQB : 10″ barrel. A Colt M4 Commando equvelent.
- SIG516 BASELINE CARBINE : 14.5″ barrel. A M4 Carbine equvelent.
- SIG516 Patrol. 16″ barrel.
- SIG516 Tactical Marksman: 16″ barrel A squad level sniper / designated marksmen rifle.
- SIG516 Precision Marksman: 20″ barrel. Possibly a true sniper rifle, or designated marksmen rifle.
They are all piston operated and feature an adjustable gas regulator like the Ruger SR-556.

Upper receiver assemblies will be sold. Just before anyone gets their hopes up, while it is likely that Sig will sell civilians models, this has not been confirmed.
Big thank you to Lusaka for the information and photos.
