I would read the ammofaq.
That sai you want as much velocity as you can get, luckily now days we have very good bullets in 5.56 that work very well out to 200yrds even with sbr's |

Here's my stats for my 11.5 using walmart green box remington 55 gr ammo.
Muzzle: 2700 100 yards: 2370 200 yards: 2075 300 yards:1800 400 yards: 1560 500 yards: 1350 I would rather never be hit by a 55 gr bullet going 1350, I'll bet your thinking the same. |

BCM did a good write up on why they build 11.5" uppers.

I edited my original post to better state my question. But to expand a little, my rifle has an 11.5 inch barrel and a permanent 5.5 inch flash hider. I bought the rifle before I had a clue as to what I was doing. Now, I use the gun for three-gun competitions and think it's a waste to have 5.5 inches of flash hider when I could have 5.5 more inches of barrel. So I'm thinking of swapping out a new 16" barrel. But if the 11.5 inch barrel has a negligible effect on bullet trajectory / accuracy / whatever, then I may use the money elsewhere.

Thank you very much. So based on that chart, I would only see about a 15% increase in velocity. That's probably not worth the cost of a new barrel and gunsmithing. Am I right? |

There is a supposed benefit of increased reliability, less wear and less likelihood of baffle strikes when suppressed. Personally if you are not having issues with any of the above I wouldn't bother moving up.
