Just bumping this one back to the top….it seems like it’s gaining a little popularity again.
This post is going to try and explain one of the more difficult combat carbine concepts to comprehend (see what I did there ?). That is the trajectory of a rifle round when firing from the “rollover” or “urban” prone position.
Before I try this, you need to review what the normal trajectory of a fired round is:
While the common phrase used when talking about a bullets flight is that a round “rises to the line of sight” after it exits the muzzle, the fact is the law of physics cannot be denied. Like water from a hose, gravity takes hold of a bullet the moment it exits the barrel.
If the bore line and your line of sight were the same, a bullets trajectory would look something like this:
So…your weapons sighting system is designed so that the barrel angles upwards in relation to your line of sight.
