Have you confirmed that these are for the Canadian TAR models? I thought they were for the American model, which I heard has a different trigger pack. I could be totally wrong, but that's just what I heard. If they do fit, or you have the American model I don't think you could go wrong with either as both make very nice triggers. I would pick the Gieselle one as I have used them in the past and they feel great, but the Timney for AR's etc I have heard are very nice as well. Also check to see if they are both drop in, or just parts.
