  M21 Remote Sensing Chemical Agent Alarm
The M21 Automatic Chemical Agent Alarm provides the Army with the first-ever capability of detecting chemical agent vapor clouds at a distance.
The M21 Alarm operates in the 8-12 micron region of the infrared spectrum.
The early prototypes of the M21 Alarm were on a tripod; however, the computer that processed all of the collected spectra and generated the agent/no agent decision was housed in a Winnebago.

 U.S. Army M21 & XM21 Sniper Weapon System
The M21 is esentially a modified M14 National Match rifle.
The XM21 began to be fielded in the second half of 1969 and remained the U.S. Army's primary Sniper Weapon System until it began to be replaced by the M24 SWS in 1988.
Besides the problem that it is semi-auto and sends brass flying, the M21 was, and still is, a very capable military sniper rifle.

The improved FOX has an integrated mast assembly that stores the M21 Alarm and raises it during vehicle short halts to scan the area for agent clouds.
Using the M21 Alarm's performance in the agent chamber and modeling to determine what agent concentrations are likely in different field situations, a series of user cards were developed to aid the soldier.

 THE BSA M21 600 - SIDE-VALVE SLOGGER
The M21 tested is a product of the immediate post-war motorcycling industry in that it shares the running gear of the war model WM20 despite being a claimed 1947 model.
The M21 initially had a bore and stroke of 85mm x 105mm for a swept volume of 595cc.
The performance of the M21 was claimed to be a solid, pumping 15 BHP, however this did not translate to top speed, with sidecar gearing 50 mph was a less than comfortable maximum.

The Mortar when fired from within the M21 also had a traversing capability of +/- 30° whereas in the M4 series, the weapon's traverse was limited to the minimal traversing gear mounted on the weapon itself.
Reinforced flooring on the M21 to accommodate the constant recoil forces of the mortar that permitted sustained main weapon firing from within the vehicle.

 Help me with Fulton M-14/M21 - THR
They (Fulton) usually charge more for the M21 marking, so I might be interested in it as some interesting collector clone of a rare rifle, I just don't know what the M21 was.
The M21 was the standard US Army sniper rifle from the late '60's all the way up until the introduction of the M24 SWS in the late 80's.
Likewise, an M21 would have had all the selector parts in place, but would have been missing the selector knob, and would have had the selector lock installed in it's place.

 Classic Motorcycle Profile - BSA M21 - RealClassic.co.uk
Bit sad to be penning this, really, as it's a farewell, as well as an advert, for my old BSA M21.
Cycle parts were overhauled, with new steering head and wheel bearings fitted, among much else; electrics were renewed and converted to 12-volt (the M21's lights are the best of all my Brits); and later the magneto was rewound.
The front end is off an A10 twin, bringing the benefit of a good single-sided 8-inch front brake, as found on the AA's M21 outfits.

Teflon® bearings at the blade pivot assure velvety-smooth one-hand opening and closing, using Kit Carson’s trademark dual checkered thumb studs which also act as a blade stop.
M21™ models feature the very popular “Carson Flipper” blade extension, which aids opening and acts as an additional blade guard.
