Shot my new Sig 556R today
I shot mine for the first time today. All I can say is with good brass cased ammo ( 200 rounds), I had absolutely no jams. When I started using the lacquer steel cased ammo I had several malfunctions. When I switched back to brass case ammo it functioned flawlessly for the rest of the day ( another 200 rounds). I own 3 Ak's, two of which are Bulgarian and I found the Sig to be a smoother more accurate rifle.
