Want to Win a BFG Sling? Which Rifle Do I Take to Thunder Ranch?

Me, Ryan, Luke, Hop, and Adam are all headed to Thunder Ranch on June 1 for a perfect storm - one day of Urban Rifle, one day of Defensive Pistol, and one day of Urban Precision Rifle). We are running 1,000 rounds through each of our rifles over the course of one day. I'm trying to decide which of my favorite rifles to bring: My BCM Mk2 Enhanced Lightweight w/MCMR-15 or my Daniel Defense DDM4V7 w/MFR 15.0. I'll take whichever rifle you guys want me to take, you vote.

Let's make a lil' contest out of it, though. Whoever most closely guesses the weight of both rifles will win a Blue Force Gear Vickers Padded Sling in Coyote.

Poll is here:
