Did some testing on the shooting range tonight. Only did the m4 556 but I imagine it would translate to all other weapons. Started with a 4 inch barrel and the 5-25 scope just for the ability to see the target at 350yds. Bullet drop was 2 mils on the scope stadia. Kept the entire rifle the same but changed to the 24 inch barrel, same shooting position same target, same bullet drop, 2 mils. Tested this with all available 556 bullets as well and there was no detectable difference in point of impact. So in theory bullet velocity and therefore “damage” is not affected by barrel length if anyone was wondering
