I was at the gun show today and spotted a Stag Arms complete lower with collapsible stock. What struck me as odd was that the hammer didn't have the notch I was used to seeing on the top front side. I asked the dealer if the lower was factory assembled with all Stag parts and he said yes.

As soon as I got home I opened up the safe and got out all three of my Stag lowered guns and inspected the hammers. Indeed all had the hammer notch I thought all Stags were supposed to have.

So my question is, did Stag change hammers or did the dealer put the lower together with non-Stag parts?
