Last year around Christmas I got a semi-custom AR with the Wylde chamber (supposed to be good for .223 and 5.56. It was made by a gun shop "Double Tap" in Clarksville, TN (near Ft. Campbell, Veteran owned).
Overall it seems well made, from decent quality "all US made" components.
However, I've noticed some problems with ammo firing. It's not uncommon to have 1 "dud" round per box of 20. They'll have the firing pin witness in the primer. Sometimes they'll fire if I rechamber them, but some I've tried 3x to no avail.
American Eagle .223 ammo seems to be the worst offender.
My question is, have others had issues with ammo quality, or does this seem like a problem with the rifle? It's the only .223/5.56 I've ever fired so I'm not sure where the problem is, but I don't know that I've ever had "dud" ammo in any other gun ever.
Could it possibly be too light of a hammer spring or something like that?
