4140 steel is a hard and durable steel used in many gun components such as barrels, bolts, and receivers. 4150 steel is similar to 4140 but with a higher proportion of carbon. It is harder than 4140 but also more difficult and expensive to machine, so it is more often used in military‑spec firearms.

Benchmark barrels
Series of units for volume measurement
A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels, oil barrels, and so forth. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common use range approximately from 100 to 200 litres. In many connections the term drum is used almost interchangeably with barrel.
Pinaka is a multiple rocket launcher produced in
Indian long-range multiple launch rocket system
Pinaka is a multiple rocket launcher produced in India and developed by the Defence Research and Development Organisation (DRDO) for the Indian Army. The system has a maximum range of 40 km for Mark-I and 60 km for Mark-I enhanced version, and can fire a salvo of 12 HE rockets in 44 seconds. The system is mounted on a Tatra truck for mobility. Pinaka saw service during the Kargil War, where it was successful in neutralising Pakistani positions on the mountain tops. It has since been inducted into the Indian Army in large numbers.
