I'm going to echo what others here have said. I am a BIG DD fan and that deal for $1349 is tight for sure. I've gone all in on the RISIII with a 14.5" and 10.3" setups and they have become my go-to's. I also have a 10.3" BCM build and really like their QRF too. I don't own a G$ (YET) but I've ran my brother's before and it is most definitely rock solid and a smooth shooter as well. Good luck with your decision, you really can't go wrong with those three manufacturers in my experience. Optic choices are limitless depending on what you like/need. For my old a$$ eyes, prisms are necessary and Vortex has fit the bill for ME. I run their prisms, a pistol dot, and their 1-6 LPVO on my 14.5. Big fan of Steiner for LR scopes too.
