It's a gorgeous rifle. Pretty sure that's the GAP pattern- Manners SL, Bartlein #3 fluted twisted 1:8.7..... I won't lie, it makes me doubt my decision to go with the Xtreme Hunter pattern which has the DBM. Very clean-looking rifle.
I'd be very surprised if you didn't end up liking the DBM. Not as clean, but feeding and convenience are great and the extra COAL is nice too. Didn't think I would like it, but after using a PT&G/AI mag setup, I really like it.
