Default What would I change in the current AR platform

A couple of days ago, somebody posted a reply regarding the modifications that I would suggest concerning the current AR platform.It's pretty "simple".
Before I continue, let me say what I like(strong points) about the AR platform(to avoid any kind of misunderstandings with the AR-fan guys).
1)It's lightweight compared to many other platforms
2)Great iron sights that allow extreme accuracy.
3)Good full-auto shooting.Thanks to its shape(especially the buttstock), it allows pretty accurate firing even in full-auto.Very controllable.
4)Quick-mag-release button.A great feature.With a single finger, you can quickly release the mag.
5)Possibiliy to mount on it almost any kind of accessory.You never know what may happen, everything may be useful.The possibility to have and integrated picatinny rail system is also a great feature.
6)Charging handle in a central position.That's good for any kind of shooter(dx and lefthanders)
7)Thumb activated fire-selector.

Time for modifications:
1)The caliber.
The 5,56 is somehow "weak" compared to the other calibers.Its strong points are the accuracy and the controllability.On the other head...let's face it:It hasn't the "punch" (stopping power) nor the penetration power of a 7,62x39.The best option would be a compromise between the two(6,3mm;6,5mm;6,8mm).
2)The room between the trunnion/chamber and the mag port
One of the factors that make the AK platform so reliable and dependable is the room between the mag port and the chamber(It results in a higher % of positive feeding).In the AR platform, there is almost no room, so it is in fact less reliable.I would increase the amout of room.
3)The gas system/gas block
Direct infringment works, but is neither the best option nor the most reliable one.A short-stroke gas system is a good compromise between reliability and ease of use.It's a well know fact that the direct infrigment is the less reliable gas system-if compared to the long-stron, short-stroke, roller-delayed gas systems.
4)Bolt carrier lenght
The bolt carrier should be shortened.To make things work, the recoil buffer shoud be shorter.The trigger group should be redesigned.There is a lot of work on this(see point 2)...it would much easier to do it if point 2 would be done by default(more room available).Why should be this done?Pretty simple:To allow the end user to mount a practical foldable stock/to shorten the total lenght of the rifle).
5)Mag release button
Usually it is on the right.They should find a way to place it on both sides.This would improve the performace when switching hands/shoulders(E.g.:On an AK, you can change the mag in the same way with both hands.There's even a component where you can add a quick-mag-release lever on the trigger guard that allows you to do it with a single finger(the index finger), but it requires a little gunsmitting.This is possible because the mag release is in a central location).

I actually don't remember any other modification right now, but I guess there are some more things that could be done.

The CZ V58 is an awesome rifle that should be taken into consideration. 800 rounds of 7.62x39 a minute striker fire rifle. That is right... a striker fire rifle. AK47 does 600 rounds a minute. The whole top cover moves to eject round instead of a side ejector like AK and AR. This results in better reliability. The Czechs never went along with the Soviets with any of their firearms.

Oh...as far as your answer in the last post.......

To be honest:I was thinking about the vz 58 and its striker....that's really a great rifle!!!My cousin has one.I shot it several times and fell in love with it immediately.I will never understand why the russians had never tried to copy its design...at least for what concerns the gas system.In my opinion, the vz. 58 was one of the first attempts to combine the western and eastern gunsmitting philosofies.I have never tried the BREN 805(the rifle that replaced the vz58) but...during my last journey..I've met a czech who has the possibilty to shoot both rifles in the cz army:He told me that he BREN represents undoubtely the future of cz weapons, but he prefers much more the vz58-and so the majority of the specialists in the cz army.
