I bought this new-to-me CMMG M4 14.5" + FH, it has a FSB and a MBUS at the rear. When I was playing it with my bore sighter, I noted that @ 25 yds, the laser dot sits BELOW the FSB.
It makes me wonder if the BUS has ever been sighted in? Does it sound "normal" in the land of M4?
Or should I adjust the front sight down until the dot is right above the front pin?
Just try to save some ammo here ...Thanks in advance
