Maybe (at least at closer ranges), but that's gotta be one of the stupidest configurations ever designed. You lose reliability and a tremendous amount of velocity, and FOR WHAT? The barrel length has to be at least 16" total anyways. Might as well squeeze out acouple hundred more FPS.

I agree with the Colonel of Chicken here. Aside from teh look, you'd be better off just going with a 16" barrel. 16" M4 or Government profiled barrels are still nice and light and give a substantial velocity increase. If you're going to get a 10.5"-11.5" barrel, SBR it. |

supposidly bbl length has no bearing on accuracy....
i'd go w/ mr stickman and colsanders w/ a +1 for the longer bbl length for more vel |

ok, i was just wondering cuz it looks cool.
How does a longer barrel increase velocity. Ive heard many people say it but i am wodering how that works. |

The bullet is in the bore longer, and the gas is accelerating it for a longer time.

Until it reaches a point where the pressure behind the bullet is overcome by the friction of the barrel, which in .223 is somewhere around 26", IIRC. That being said, a match quality 10" barrel will be more accurate than a rack quality 20" barrel. The quality of the barrel and ammo will have more impact on accuracy (as long as the bullet is supersonic and stabilized) than length. Length = velocity. |

Yes, it would be as accurate, but its velocity would be much lower. If its a paper puncher, and you don't shoot at long distances, it won't matter to you. Shorter barrel length AR15/M16s have killed plenty of people, its just a little more limiting with its options.
I would take a guy with skills and a short barrel, over a guy who fancies himself as big daddy tactical backing me up any day of the week. If you know the pros and cons of the 11.5/5.5" configuration, you are fine. The below pictured is one of my favorite ARs, but it isn't the one I choose to carry for duty.  |

Like stickman says, the 11.5x5.5 barrels work.
However, why buy something that is an long as a 16" barrel with a birdcage, but performs like a much shorter barrel? Either Form 1 the rifle and use an 11.5" barrel or get a 16" barrel, or is you want a Title 1 weapon with the look of the XM177 call Bushmaster and buy their flash suppressor--the one that looks like the moderator but threads onto the end of a 16" barrel and covers the barrel. |

If you just like the look, you can find flash hiders that telescope back over the barrel to give it the same look without losing the advantages of the longer barrel.
