Is HK416 the greatest since humanity?

A simple answer. Hell no!

HK is great in advertising and promotion. Every little thing, they can gold-plate it so well that everybody think only HK products are worth buying. No matter what they do, many would think logical mind should always prevail; however, the world is filled with emotionally charged people where reasons and logic rarely exist.

Sticking a piston into an AR15 does not make it instantly superior. Firstly, piston design is even older than the AR15's direct impingement design. Countless manufacturers have produced pistons for AR including Colt - the army rejected such design change many times, but when HK finally did it and called it HK416, it's suddenly the greatest in the world? Anybody claims so is very dishonest to say the least. Why?

1.The 416 has NOT seen any major battle - compared to M16's 40 years combats in countless wars (note the plural)

2. The 416 has NOT not been properly tested by any major military/LE agency compared to M16/AR15 which is widely tested and accepted by many major armies in the world (note the plural)

3. The 416 has NOT been produced in any meaningful number to generate much statistics on reliability and usability - compared to M16/AR15 which is made into the millions (note the plural).

A weapon is just like everything else in the world. Adding any new feature, there's always a possibility that it causes more failures. It takes time and money to work out the bugs. When one compares HK 416 with M16 (AR15), there's no comparison - one must not make such comparison. Not because HK 416 is so much better, but it's mostly because there's hardly anything that can be used to compare.
