How can a 200 dollar rifle selling for 1000 dollars be considered affordable?
Where's the $200 rifle that's selling for $1k?
Wait, so it's one person's fault that a whole military used a crap version of something that "may" have worked well? We're blaming one person for a gun that malfunctioned terribly when it first saw service?
McNamara was Sec Def, so yes, he and his penny pinching cronies are the ones who messed up the design. Again, the gun worked as Stoner designed it. The M16A1 remedied the problems of the McNamara neutered M16.
Did it take 50 years for (pick a gun) to come down to a reasonable price and be very reliable? Or did it just work like a gun is supposed to?
It didn't take 50 years. The M16 entered service in 1962. The M16A1 entered service in 1967. It was five years too many, and those first five years are what gave the whole rifle family its bad reputation. If the rifle had been manufactured as engineered, proper ammunition components used, and minimal cleaning gear issued there would have never been problems. Again, do some research.
And wasn't there just a story a while ago about how the 5.56 is ineffective at longer ranges which is where it is more accurate than the AK?
Neither the AR-15 / M-16 nor the AK-47 were intended to be used on point targets beyond 600 meters. Further, the story you're referencing is in regard to the M4 carbine. The M4's 14.5" bbl greatly reduces bullet velocity when compared the M16/A1/A2/A3/A4 20" bbl. You're also ignoring the ammunition. M855 ball was never intended for use on unarmored personnel. M855 ammo was developed for the Cold War where we would be facing opponents wearing body armor. Reissuing the M193 ball ammo, which yaw's and more heavily wounds unarmored opponents, has increased effectiveness against insurgents (who typically don't wear armor). The military (not civilian) M16 family of rifles are assault rifles, not main battle rifles. In a true testament to the M16 family of rifles' versatility simply adding optics, and heavy match grade ammo (Mk262 Mod 0 / Mod 1) has allowed them to used as Squad Designated Marksman Rifle (or acceptable MBR substitute by just sighting the irons in for the heavier ammo).
To recap:
1. It took 50 years to become truly reliable.
2. It took 50 years to become affordable.
3. It is ineffective at longer ranges.
1. Wrong, see above, it was reliable as originally engineered.
2. See below.
3. It was never intended to be an MBR, but with improved ammo it actually does work at longer ranges.
2. Affordability - Name another forged aluminum receiver, chrome lined bbl, semi automatic, match grade sight equipped, rifle with the tolerances an AR-15 has that costs less. The fact that you can get a quality AR-15 for $600 when a slapped together plastic frame is $500 makes an AR-15 an amazing value.
