So I just traded for a DD M4V9 S2W. I've always admired the MK12, so I've decided to slap on a 2.5x10 scope on it. I've already placed a sopmod buttstock on it and I'll put my preferred geiselle trigger in it (I like the super dynamic-enhanced) and my Harris bipod. Basically, an outward appearing old MK12 with a longer rail. While watching a video, it stated that the DD MK12 was DD's intro into the precision rifle market. So, my question is: is the S2W version going to perform as well as the Mk12? Any and all insight will be much appreciated. Does anybody own both? Are the differences subjective? Or does the Mk12 truly offer more than the heavy 42 ounce?) barrel on my weapon.
