the quantity is going to be (section x thickness), yet of course you pick the section, thickness and quantity in like minded unitsThe density is in g/cm^2, so which you will % the quantity in cm^3 and the section in cm^2a millionUse density M/V to discover the quantity2Use V A thickness to discover the thickness, which would be in cm3Convert cm to mm.
The mass is 3.366 g and the density is 2.699 g/cc, so from that you can work out the volumeVolume mass/density 3.366/2.699 1.247 cubic cm Now you know the volume, you can work out the thicknessSurface area x thickness volume Therefore thickness volume/surface area 1.247/929.030 0.00134 cm1 sq.foot 929.030 sq,cm
1) Use as many rounds at the range as you want/affordUnless you have a high end competition class rifle, there is no break-in period2) Clean/lube the BCG and quick clean of the bore and receivers when you come back from the rangeA more thorough cleaning every 500-1000 rounds or if you don't plan to use it for a long time3) To learn how to dissemble and clean, first RTFMThere are also tons and tons of YouTube vids on cleaning AR-15s4) You only have to worry about melting front sight if it is directly mounted on the gas block5) Generally if you are allowed to possess an AR, you are allowed to use it as home defenseThere are many opinions as to the usefulness of an AR in that role and laws in different states vary widely on what might be considered justified or nor for home defense6) Foregrips have their purpose and there are a variety of styles and ways to use them They will not help you to shoot more accurately, but they may help control the muzzle when you fire rapidly or have many targetsI suggest you first learn to shoot without the foregrip and take advantage of YouTube to see how people use them.
