What is the effective range of a M4 in the prone position?
451106
firstly, it depends largely on who's firing. but all marksmanship jokes aside, the maximum range of an m4 is 3600 meters. maximum effective range for a point target is 500 meters. and for an area target is 600 meters.

I prefer the 5,56 mm AR- M4SF , fits nice, great range, easy to clean. Hits harder than a paintball gun too. At 500 Meters it's not looking good for the "target".

I get that the maximum distance that the ship can fire is 6371m, meaning that any distance greater than 3571m from the western shore should be safe.  It may be tempting to assume that the target ship would be safe within a certain minimum distance, where it would be protected by the mountain peak, but the enemy ship could hit any target within the 3571m limit by angling its guns higher than 45 degrees.\n\nEDIT:\nTo start solving our problem, let's figure out the maximum distance that the enemy ship can fire.  It's not hard, and we know we'll have to figure it out anyway.\n\nIf the ship fires its projectile at exactly 45 degrees, the projectile will make a parabolic arc through the air.  At angles of more than 45 degrees, the projectile will fly higher, but it won't go as far (like a pop-up fly in baseball).  At angles less than 45 degrees, the projectile will fly lower, and hit the water with more horizontal motion (like a line-drive in baseball).  At exactly 45 degrees, it will achieve its maximum horizontal distance.  \n\nIn order to figure out how far the projectile flies, we need to break up its motion into horizontal and vertical components.  Imagine a right triangle with a hypotenuse of 250 units and one angle of 45 degrees.  (The other angle will also be 45 degrees, but that doesn't matter for now.)  The line adjacent to our angle will be as long as the projectile's horizontal momentum.  The line opposite the angle will be as long as the projectile's vertical momentum.  We just need a little bit of trigonometry to figure out these numbers.\n\nsin(a) = opposite / hypotenuse;\nsin(45) = Vv / 250;   (Vv represents the vertical velocity)\nVv = sin(45) * 250 = 177m/s;\n\nSince we're using a right triangle with two 45 degree angles, both sides will be the same length.  If we were using a different angle, we could easily solve for the horizontal momentum using the Pythagorean Theorum.\n\nSo, we know that our projectile had a horizontal velocity of 177m/s and a vertical velocity of 177m/s.  Let's figure out how long it would stay in the air.  We know that it's constantly accelerating towards the earth due to the force of gravity.  Our answer lies in the definition of acceleration: acceleration is a change in velocity over time.  Mathematically, that's (a=ΔV / t).  The "Δ" symbol is the Greek letter delta, often used to represent a change in a value.  \n\nTo figure out how long it stayed up, we only need to worry about the projectile's vertical velocity.  We know that it's initial vertical velocity is 177m/s.  We also know that it's vertical velocity at the top of the arc is 0m/s.  The change between these two points in time is (177m/s - 0m/s =) 177m/s.  The only other thing we need to figure out time is the acceleration due to gravity.  On Earth, it's always 9.81m/s^2. So...\n\na = ΔV / t;\n9.81 = 177 / t;\nt = 177 / 9.81 = 18.04 seconds.  That's how long it takes the projectile to reach the top of it's arc.  It will take equally as long to reach the bottom of it's arc, so the total flight time is 36.09 seconds.  \n\nNow we have a simple distance equation.  Since distance is equal to velocity multiplied by time, the projectile's horizontal distance will be equal to its horizontal velocity multiplied by the amount of time that it stayed in the air.\n\nd = 177 * 36 = 6372m.  (This number is a little higher than the first one, because I rounded a little differently.  It doesn't make a huge difference.)  If we take out the distance to the western shore (2500m + 300M), we get a maximum distance of 3572m from the western shore.  Any ship beyond that distance will be safe.  \n\nAll we need to do now is figure out whether or not the enemy ship can fire at that maximum distance.  If the mountain is too high, the ship will have to increase the angle of its guns, thereby losing range.  We can figure out how high our projectile is going to fly with

The M18A1 Claymore Antipersonnel Mine is a weapon often used by many countries around the world, named after the large Scottish sword, by the inventor, Norman A. MacLeod. The Claymore is designed to fire steel balls (shrapnel) out to about 100 meters (328 ft) across a 60° arc in front of the device, which stands just off the ground. It is designed primarily to be used in ambushes and as an anti-infiltration device against enemy infantry, however it is also of some use against soft-skinned vehicles.

Depends on the model.  The normal range is between 300 fps and 1000 fps.  I have seen specailty rifles that can be adjusted to fire at 1500, which by the way is faster than a .22 LR.

m-16 the ak is more durable but the m-16 has better max effective range, more accurate and higher muzzle velocity and rate of fire. ak47= 7.62mm round rate of fire is 600 rounds a minute muzzle velocity is2350 feet per second and has an effictive range of400m (1312 ft) m-16=5.56 mm round which is a smaller round but...rate of fire is 800 rounds per minute 200 faster than ak 47 muzzle velocity is 3280 feet per second and has a 500 m effective range, so the m-16 shoots faster more accurate and shoots farther

Depends on the weapon and the bullet. A 5.56mm round fired from an M-16 exits the barrel traveling at about 2,900 feet per second. At ranges under about a hundred meters, the bullet is traveling fast enough that it fragments on impact, which opens up a huge wound cavity. But at ranges greater than that, the bullet slows down to the point where instead of breaking up, it retains it's integrity and gets deflected by bones, muscle, and various other tissues that can change it's trajectory. Heavier rounds, such as the 7.62x39mm (AK round), or the 7.62mm NATO are less effected by tissue and bone and usually continue their course in a straight line.

Firing at a target that is immediately in front of the weapon.  Ranges are usually measured in yards, for example 3.5yd = "three point five yards".  When you fire so close that it is immeasurable, it is 0.0yd.  People dropped the first "zero", and slang made the second zero read as "blank", so 0.0yd became "point blank" range.

Max range is well over 1000 yards - I shoot my 308 at 1000 from time to time, and that's considered a moderate-powered rifle. 338 Lapua Magnum or 300 Winchester Magnum can reach well beyond a mile.\n\nAt those distances, there are really 4 factors that limit accuracy. Firstly, the precision of ranging equipment that is used. If I estimate a target at 1200 yards but it's really at 1400 yards, I might miss it entirely - or fire a shot at the knees rather than the chest.\n\nWind is another factor, and over a mile's distance the wind can vary. 300 yards out there might be a 10mph wind from the left, but there might also be a 5 mph wind from the right at 800 yards. This will have serious effect on the shot's path.\n\nThe accuracy of the rifle is important, too. Accuracy is generally measured in "minute of angle", or roughly 1 inch at 100 yards. So, a 1/4MOA rifle (fairly common among precision rifles) means the shot will vary by 1/4 inch at 100 yards. That also means that at 1400 yards, the bullet's impact can vary by up to 3.5 inches. That's enough to miss a marginal head shot, and that's under controlled conditions, which the sniper never has.\n\nThe last one is, of course, the sniper himself. At short distances the mere act of breathing can have an effect on the rifle; it will bob up and down in time to your lungs. There's a simple fix for that, though - stop breathing long enough to acquire the target and squeeze off the shot. There's a factor at long range that you can't overcome, though - your heartbeat. Your rifle will also move, ever so slightly, in time to your heartbeat because your blood vessels actually move you through hydraulic action. Just a bit, but enough. experienced long-range snipers will not lie prone, but actually prop themselves up just a bitso only their knee and elbow bones are touching the ground. Blood doesn't flow across those surfaces, so heartbeat doesn't move you as much. It's still visible because of your hands, but it's less than your arms or legs. Acquire the target, "learn" where your heatbeat is guiding the reticle, aim, and squeeze between beats.

I have read that while the 50 BMG silencers reduce noise by over 30 decibels, none of the ones on the market today actually make them safe to shoot without damaging your hearing.  They also are less effective at reducing recoil than a muzzle brake.\n\nI own and shoot the 510 whisper on my TC Encore.  It uses the 50 BMG bullet seated in a 338 lapua case cut down to 1.885", and uses about 30 grains of pistol powder to move the bullet at about 1050 feet per second.  The rifle sounds like a car door slamming when suppressed.\n\nThe downside is that any bullet moving at 1000 fps is dropping rather fast when it passes 200 yards.  This means you must be able to estimate range to the target very accurattely to ensure a hit as the trajectory is very steep

I dont know why you would want a scope on a M4 it is short barreled, and its use is mainly used from inside vehicles with short bursts, Having been there I can say the preferred weapon of the PSDs and military is the AK having seen the failure rate of the M4 if you want to come home alive use an AK

Not accurate at that range. try a 7.62mm

Lasers are meant for close quarters sighting, the scope on your rifle is obviously meant for 100 yards or more, under the front lens cover there should be 4 set screws you use to fine tune your laser to dead zero impact.Simply unscrew the front lens cover to access these screws. Considering most lasers cannot be seen past 25 yards in daylight conditions, your best bet would be to zero the laser at 25 yards, and use the scope for farther out. I have a 35mw green laser that can be seen at 50 yards in daylight conditions, but I doubt seriously a 35mw or higher red laser can be seen that far. The human eye see's green better than red. It's not certain your laser sight zero's in the above prescribed method, since you didn't list it's maker, the one's I'm familiar with zero with set screws under the lens cover.Also you may want to consider a high rise scope mount to use iron sights for between 25 and 100 yards, this way you have 3 sets of sights on your rifle, each one set for a specific distance and condition.

The 9mm will take about anyone. It is very effective here in Afghanistan and was effective in Iraq too. I prefer the M4 and M24 more. Being able to reach out and touch someone before they can fire back is the safest way to go.
