The AK-74 (5.45x39mm) is slightly
less powerful than the M16, not twice as powerful. 7.62x39mm (AK-47) is
slightly more powerful. .308 Winchester/7.62x51mm is nearly twice as powerful.
The M16's direct-impingement gas system is definitely more sensitive to dirt and underlubrication than the Kalashnikov piston system and its generous receiver clearances, but the M16 (and its non-automatic civilian cousin, the AR-15) WILL work if you keep the bolt carrier well lubricated (the dirtier the environment, the more oil you need) and the ejection port cover closed. If the bolt carrier gets dry, it will lock up if there is much grit in there. Underlubrication is the cause of most failures.
30-round magazines (not "clips", clips are for loading magazines) are used because they are a nice balance of capacity, size, and weight. The 100-round magazines (Beta-C mags) this guy is talking about certainly look "kewl" in the movies and video games, but are VERY finicky, susceptible to damage if dropped or whacked, slow to reload, bulky to carry (30's are flat, 100's aren't), and really screw up the rifle's balance. The M16 isn't a squad auto and was never intended to be.
The guy trashing the M16 is trying to sell his competing rifle. AFAIK, England, Germany, and Switzerland have NOT adopted the Ultimax; only Singapore has. That doesn't mean it's not a good rifle, but he's definitely overstating the case for it.
"Designed for firing from the hip"? Please. Look at the grip angle; it's made for firing from the shoulder. The sights (arguably the best on any military rifle). The adjustable stock. The optics (yes, those $500 Aimpoints are on there merely to look kewl when hip-shooting). Don't forget that he's trying to sell
his rifle...
The term "assault rifle" is a translation of the German word
Sturmgehwer (storm rifle) and refers to selective-fire rifles and carbines firing reduced-power rifle cartridges.
"Hanging more stuff off the rifle compromises its reliability"? Nope. External stuff doesn't affect internal function. Optics and lights make a rifle a lot more usable, though. The main developments in small arms (both military and civilian) in the last 40 years have been in the area of optics and accessories.
BTW, the coolest picture I have ever seen of a direct-impingement gun being fired...check this out.
http://www.m-mason.smugmug.com/gallery/3489781#196589531That is a civilian AR-15 (non automatic), but the gas system is the same as the M16. Combustion gases are tapped from the barrel at the front of the handguards, where the pressure has dropped to 3000 psi or so, and piped into the receiver, where the gas pressure launches the bolt carrier back and initiates the reload cycle. A really fast camera can capture the gas flame in the open ejection port, where the hot gases from the gas tube meet fresh oxygenated air in the receiver (that's mostly a hydrogen flame, IIRC). The AK system confines the hot gases to the front of the handguards and uses a long piston to move the bolt carrier instead. The advantage of the AK system is that it keeps the receiver cleaner, and adds more reciprocating mass for reliability; the advantage of the AR-15/M16 system is that it allows extreme accuracy if the gun is tuned for it (as tight as 1/4 arcminute precision with some civilian AR's).
Sometimes I wonder if they promote variations of the M-16/AR-15 so much in the US cause they have trouble exporting them.
No, most of the civilian AR-15 market is served by different companies than those that make the M16. FN Herstal has the M16 contract, but most civilian AR-15's are made by Bushmaster, Stag, Rock River Arms, DSA, Colt, Armalite, Olympic Arms, DPMS, and a number of smaller companies like Lewis Machine & Tool. Colt does make M4's for the military, though. There are significant parts differences between M16's and AR-15's as well.
Israel even builds a machined clone of the AK.
They used to (the Galil). Israel now uses M16's, although they have recently designed their own selective-fire bullpup (the Tavor) to replace them.
