The collection of these software items has been enhanced into the “suite” of NATO shareable fire control software. Significant development effort occurs in Aberdeen, Maryland, USA in the Firing Tables and Ballistics (FTaB) [ 3 ] Division, Armaments Research, Development and Engineering Center (ARDEC) with contributions from a variety of ...
To fire the grenade, firstly a special blank cartridge is loaded into the weapon. There is often some sort of cutoff device on gas operated rifles that can be engaged to disable the gas piston, both to eliminate the possibility of a live round chambering itself, and to prevent any of the gas being tapped off, which might affect the accuracy and range of the grenade.
The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]
The M6 cans were for packing .30 Carbine ammo and weighed about 25 lbs. The M8 cans were for packing .30 Rifle & Machine gun ammo and weighed about 16 lbs. The M10 cans were originally for packing .50 Machinegun ammo but later on were also used to pack shotgun shells or a variety of other ammunition in cartons.
The hooded front sight is installed in a post on the gas block and is also adjustable for elevation and windage. Early models of the Minimi had the rear sight mounted forward of the feed cover and the front post secured to the barrel, closer to the muzzle end. An adapter can also be used that allows the use of standard NATO night and day sights.
Although this is a NATO-standard round, it can only be used with the Type 10 Cannon due to the increased load and resulting increased pressure when fired.

The civilian organisations C.I.P. and SAAMI use less comprehensive test procedures than NATO, but NATO test centres have the advantage that only a few chamberings are in military use. The C.I.P. and SAAMI proof houses must be capable of testing hundreds of different chamberings requiring many different test barrels, etc.
The M60's gas system was simpler than other gas systems and easier to clean. The M60 was designed for mass production, like the MG 42 it was based on. While the M1919 required much machining for its large, recoil-operated internal mechanisms, the M60's stamped sheet receiver had a gas-operated, carrier-cammed bolt mechanism; the same type of ...
