A barrel, cask, or tun is a hollow cylindrical container, traditionally made of wooden staves bound by wooden or metal hoops. Traditionally, the barrel was a standard size of measure referring to a set capacity or weight of a given commodity. For example, in the UK a barrel of beer refers to a quantity of 36 imperial gallons (160 L; 43 US gal). Wine was shipped in barrels of 119 litres (31 US gal; 26 imp gal).
Modern wooden barrels for wine-making are either made of French common oak (Quercus robur) and white oak (Quercus petraea) or from American white oak (Quercus alba) and have typically these standard sizes: "Bordeaux type" 225 litres (59 US gal; 49 imp gal), "Burgundy type" 228 litres (60 US gal; 50 imp gal) and "Cognac type" 300 litres (79 US gal; 66 imp gal). Modern barrels and casks can also be made of aluminum, stainless steel, and different types of plastic, such as HDPE.
Someone who makes barrels is called a "barrel maker" or cooper. Barrels are only one type of cooperage. Other types include, but are not limited to: buckets, tubs, butter churns, hogsheads, firkins, kegs, kilderkins, tierces, rundlets, puncheons, pipes, tuns, butts, pins, and breakers.
Barrels have a variety of uses, including storage of liquids such as water and oil, fermenting wine, arrack, and sake, and maturing beverages such as wine, cognac, armagnac, sherry, port, whiskey, and beer.

    Ballistic Advantage 14.7" 5.56 Mid Length Pencil Barrel BRAND NEW

    Brand new BA 14.7" pencil barrel. The 14.7 is nice because you are able to pin and weld a standard length flash hider to meet 16" barrel length instead of needing an extended one on a 14.5. Barrel is brand new and never installed or fired. Just decided to go with 16" instead.
