NS, my 505 Gibbs had a set trigger which I removed and replaced with a Timney version which is very nice and no set trigger. I personally wouldn't have a set trigger on a DG rifle as there is a risk of accidentally setting it and you are not taking long sniping shots with that sort of rifle anyway. The one that came with the rifle certainly worked well when used as a normal trigger but under inspection with an Optivisor during pulling would rotate internally so that you were getting only a fraction of the sear contacting rather than the whole blade, which is a recipe for accelerated wear. So I replaced it and am happy with the Timney unit.
