Thought I'd do a review of my Sig 556 after its had a few rounds thru it. So far I've run about 1500 rounds thru this rifle: mostly PMC but some Hornandy, Federal, and Tula. So far I've had 1 malfunction, a failure to fire. Of course, this occurred during a rifle match, while the timer was running. I didn't recover the round so I don't know if it was defective or if it got a light hit.
The assembled rifle. Pretty much stock Sig 556 Classic.
Flash hider wear. Flash hider is from PWS and has been installed since I got the rifle.
Receiver wear from the cartridges impacting the side of the receiver. They all so that and they all dent cases too.
Field stripped. Little more complex than the parent AK design.
Gas piston head.
Gas regulator. No signs of erosion.
Bolt striped. The extractor is not normally removed except to replace it.
Bolt face wear.
Trunnion showing cam wear on the initial rotating cam.
Trunnion showing where the bolt carrier impacts on the right side.
Receiver rail wear.
Ejector.
Bolt carrier.
Receiver buffer plate.
FCG.
To summarize, I'd classify all the wear on this rifle as being parts polishing themselves in. I haven't seen any signs of peening or other destructive wear. The parkerizing has worn off in places and the paint has too, but there just isn't any metal being removed in significant amounts.
