Finally, after two weeks of waking up at 0300 in the morning and not getting back off the range until 1930... (16 hour work days) ... I got my 2nd Expert Rifle Qualification in the Marine Corps. The first one I left boot camp with a year ago using Iron Sights and never ending windage adjustments. My last qualification was with the new ACOG or RCO scope now used on the service rifles. (This order came in effect starting in October of this year, now all Marines are to qualify using the RCO scopes instead of Iron Sights.
My rifle is an M16A4 with rail system and the RCO attachment. Some of my buddies got M4 Carbines (shorter version of an M16), they're pretty much the same thing. I prefer the A4 because it fits my shoulder well and is much easier to clean.
For those who don't know, basic rifle qualification in the Marine Corps is based off of two "Tables" or types of firing. The first: Table 1 consists of rapid and slow, well aimed shots from 200 yards to 500 yards. Table 2 is more combat oriented, here you actually wear combat gear (body armor, kevlar helmet, etc...), and the firing techniques are short range but quick and tactical. The Marine is evaluated on accuracy in the "head shot" (brain shots) area and the vital shots (shots that'd hit the heart), while practicing tactical and speed reloads on the firing line. An example would be something like a "Box Drill". This simulates firing on two enemies and finishing them off each with a head shot. It'd go two chest shots on target "A", two chest shots on target "B", head shot target "B", head shot, target "A". Table 2 also consists of shooting at moving targets.
On Table 2 I got 6/8 on the moving targets from 300 yards, and the rest perfect...save one chest shot that strayed off a bit to the right, but all my headshots we're perfect.
