E. the scope that does come with M110 is (IMO) a POS. We had to have guys tape the battery compartment so it wouldn't vibrate loose, screws for the W/E would back out or strip, wouldn't hold zero, wouldn't track correctly and a bunch of other problems. Honestly about the only thing I liked about it was the TMR reticle. When given the option everyone in my detachment replaced them with a Nightforce.
