A 10.5" barrel noveske is 28" OAL with the stock fully collapsed. With the stock adjusted to where I'd be comfortable shooting its roughly 4" longer than the Tavor. So, if you wanted a AR that has the same OAL as a Tavor your looking at 7.5" barrel
The Tavor is 29" OAL with a 18.6" barrel
A 18.6" barrel has better ballistics than a 7.5"-10.5" barrel.
True or false?
It's a simple question that has only one answer. Please try to answer without, but but. But that only matters with M885, yap yap yap.
I'm about done with this argument. You like the AR better. Good for you. I like the Tavor better, so what of it? I could care less if you don't value my opinion, as I clearly don't value yours.
Again, its "an AR" not "a AR" and its "you're" not "your".
No doubt the velocity and thus the performance of CERTAIN projectiles will be much greater from a longer barrel. Much like your lack of grammar you don't understand that the projectile choice can and does influence the decision on barrel length. Projectiles aside, I never said a 7.5" AR was viable or recommended, I also never said a 10.5" was desirable. If you do some research, which you clearly have not, an AR with an 11.5" barrel is ideal. Nevertheless, lets use the 10.5" as that is what the MK18 uses(if you are unaware of what a Mk18 is try google). Again, the advantage of a bullpup is its compact size with a longer barrel which equates to increased velocity. That is it, nothing else about a bullpup is an advantage over conventional rifle designs. So, such a compact rifle with increased velocity is a benefit in confined spaces, CQB/CQC/FISH etc etc. The ranges you'll encounter are less than 25 yards. If we look at M855 or M193 they require 2500-2700 fps for reliable "tumbling" or yaw action, and 2700fps and up for reliable fragmentation. Have a look at some published numbers below.

These numbers are from an owner of a 10.5" AR. Note, the Q3131 which is M193 ammo. The velocity is definitely higher than the minimum required for maximum terminal performance. The 75gr stuff performs at nearly all velocities, and Mk262 77gr ammo is available and in use by those who require gear for CQB work and it solves the velocity vs performance problem.
here's some more info for you.

These are not my opinions as you clearly feel they are. This is called fact, hard data that is indisputable. I do like the AR more than a bullpup, but its not because of my opinion, its because bullpups are dumb designs that solve exactly zero issues.
You say there's no chance of ever having to use my firearms for "combat" and you may be right. In fact, lets go with that theory for a minute. If we never need them for defence of life, then why are you so concerned about terminal performance and thusly barrel length? These rifles are simply "toys" right? If all we do is compete or plink with them then discussing terminal performance is entirely a moot point, yes? With that being said, it would be a wise decision to run a short barrel AR for competition. Its lighter, its faster to swing and it doesn't suffer from the issues of a bullpup. Lets not forget, an AR is far cheaper than a Tavor and much easier to support. So again I ask, where's the advantage?
On another note, if you're running your stock more than 3 positions from closed, you're likely wrong. Try squaring up to the target, its far more effective and doesn't limit your motion.

I never said optics were required said:
The L85 is a piece of sh*t. The FAMAS is a piece of sh*t, the fS2000 is a piece of sh*t. The QBZ is a joke, and a piece of sh*t. Of the nations who issue regular soldiers a bullpup(keep in mind Israel as mentioned is a conscript army, and regular soldiers are hardly informed or skilled users, nor do they get the choice of what to use) which ones run a bullpup for their SF units? You know, the guys who actually put effort into their profession and have the option to run what they need.
I'm not disputing your experience in the CF, just the use of CF designations for what is an AR. No one cares what the CF calls them as they're still an AR. Your cheek weld with magnified optics is kind of important. I would have thought you'd know that having used the Elcan and its pathetic eye relief. Brass in the face is an option, but its a negative that one doesn't have to endure. Its a design flaw in bullpups, which again, solve zero issues while creating others.
The T97 is a non starter, the Irons aren't adjustable, at least not properly, there's nowhere to mount lights, optics or other accessories. The control layout is plain stupid and counterproductive. It is absolutely not ambi in any way shape or form, and as of recently posted, it is self destructing with use(check the Type97 rail wear thread). Tell me what awesome attributes the T97 offers that an 858 or AR or XCR or Swiss doesn't offer?
