Look Regisvo, I've spent time in the sand box with the M16 platform. It works. It never failed me when I needed it. You give me a gun and I can make it fail any damn test. Every firearm ever made needs to be cleaned and lubricated to work properly. Some firearms have a loser tolerance then other. There are trade offs.
The 1911 series of pistols are very accurate but they need to be cleaned and lubricated more often then a GLOCK series pistol.
The whole issue of tolerance means that your gun might work in some shitty environments but it won't be accurate.
Proper firearms training means that if you keep your weapon clean and lubricated that it will work. I have real hard earned experience in this subject. Don't get into an argument that you cannot win.
The Chi-Com QBZ-95 entered PLA service in 1997. It fires the 5.8x42mm Centerfire Cartridge. It has an overall length of 760mm, a total unloaded weight of 3.4kg, a barrel length of 520mm, a rate of fire of 650 rounds per minute, and a standard service load of 30rd per magazine.
The action is a gas operated, magazine fed, automatic weapon with a bullpup layout. It has a short stroke gas piston and a rotating bolt. The charging handle is located at the top of the receiver, under the carrying handle. The housing is made from polymer, with an integral carrying handle, which holds the rear sight base, and has mounting points for optical or night vision scopes. The ejection port is made only at the right side of the weapon, so it cannot be fired from the left shoulder. Standard sights are of the open type, graduated from 100 to 500 metres. The front part of the barrel in the standard version is left unobstructed, so the QBZ-95 rifle can be used to launch rifle grenades. It also can be fitted with an underbarrel grenade launcher or with a knife bayonet. Fire controls of QBZ-95 rifle consist of a trigger and a safety/selector switch, located (quite inconveniently) at the rear left of the receiver, behind the magazine housing. QBZ-95 can fire single shots or bursts. the magazine is rocked into place like the AK series or FN FAL Rifle.
Here is the main issue. THE RIFLE HAS NOT SEEN ANY MAJOR CONFLICT.
The M16 weapon system that you are bashing has had some rough times in it's past (has does most firearms when they're new). Most issues can be traced back at operator error, not design. But it has been in major service for the last 45 years. It is used by major military powers. It has fought battles in every world climate. Most nations that used former Soviet style weapons are switching over to the M16 weapon system.
Don't open up a can of firefight if you cannot back up your claims.
The US Military will continue to look for a replacement rifle because that is the nature of the beast. Sure, the M16 has been working like a champ but if someone can make a better rifle then guess what. We're going to go for the damn better weapon. It's why we went from the Spring Trapdoor rifle to the 1896 Krag and then from the 1896 Krag to the Springfield 1903. Then from the Springfield 1903 to the M1 Garand. Then from the M1 Garand to the M14. Then from the M14 to the M16. What will come after the M16, I don't know. Maybe a Phased Plasma Rifle in the 40Watt range? (Please tell me that some folks understand the joke.)
The Chinese QBZ-95 is nothing new. It's the same gas system as an AR-18. which guess what. It's an American Design. Designed by the same man that made the M16 rifle (AR-15). Eugene Stoner. It was designed to be a cheaper rifle to be produced for nations that cannot afford to produce the AR-15. The AR-18 is made of stamped metal instead of machine cut aluminum receivers. The AR-18 gas system and basic design have been copied into the British L-85/SA-80 Rifle and the now famous German Heckler and Koch G-36 series of rifles.
I say it once and I'll say it again. If you listen to the People's Republic of China long enough. They'll damn tell you that they invented water and oxygen.
EDIT: The whole issue of the QBZ-88 Sniper Rifle is battlefield tactics. It's called DM (Designated Marksman). The US Armed Forces does the same as does every other damn military power.
