HK G3+its assault rifle derivatives
-a lighter version
-with integrated rail system
Comment:The G3 platform is one of the best ever made.Why didn't they develop it/why did they abandon it?
The actual design is complicated and expensive. Plus it really wasn't any better than a FAL but at a much higher cost.
-with short stroke gas system(Until HK416)?
-with foldable buttstock(redesigning the working mechanism)?
Comment:Colt and the other manufacturers had 50+ years to switch to short-stroke gas piston.Why did they stick to the direct inf.??!??!
There are actually a number of manufacturers that use a gas piston.
The DI system is so common because it is relatively cheap and "good enough" for common use. Interestingly, the US Military has looked at gas piston systems to replace the M16 but have put high standards in place. I think their view is that if they are going to spend almost twice as much per rifle they need to be at least twice as reliable.
Interestingly, the current M4 Carbine cannot come close to passing the reliability standard they are currently using to evaluate a replacement. It's a topic worthy of its own discussion.
-a lighter version of it, less bulky?
-an assault version of it(chambered in 5,56)?
Comment:The M14 has a great, battle-proven design, but it has defined as bulky, heavy and too long.Why didn't they tried to build lighter rifle, possibly an assault rifle?
They do make lighter stocks now, but the M14 is just a heavy weapon. When you chamber a round like that the weapon has to be strong enough to handle it, and sometimes that just takes a lot of metal.
There is a 5.56mm version. The Ruger Mini-14, which is offered in a select-fire version for law enforcement. I think it's called the AC556.
The Mini-14 is known in Hollywood as "The Jamless Wonder" because it's one of the few weapons that will reliably cycle 5.56mm blank ammunition. Having fired blank ammunition (military spec, not the extra flash and dirt of Hollywood rounds) I can attest that nothing fouls up a weapon faster. I'd rather clean mud out of a receiver than try to clean up a weapon that just fired a couple hundred rounds of blanks through it.
-A short-stroke gas piston rifle?
-a 10 cm (a little less than 4 inches) longer barrel(To match the m16 one's length)?
-an integrated rail system(I mean...top cover+gas tube)?
Comment:AK platform is very reliable but even well known for being uncontrollable and inaccurate.This problem might be solved with a longer barrel ans short-stroke piston gas system.Why haven't they never attempted to do it?
Staying the hell away from this one. My knowledge of AK's is just too limited.
