Hi every one, I am looking to buy an upper with 16" or 20" barrel. Will longer the Barrel be more accuracy. I like to know how different is the 16" and the 20". Thank you

accuracy is up to you. depends on what you plan on using it for. if you want to shoot far away targets get the 20" and close targets 16". barrel length is more of a range issue than accuracy.

The 20 inch will get you more velocity for longer range shooting. It's all about what you're going to use it for.

If you will be standing up a lot more get the 16 inch. If you are going to do more bench shooting get the 20. Better yet just get both. Thats what is great about ar15, you can customize what ever you want because the upper in interchangable. How about getting a 36" bohica upper and call it a day.

It will get you higher velocity, which translates to a flatter trajectory when shooting long distance.

Since you are asking the question, I am going to guess that you won't be shooting long distance matches with your upper. Get the 16" and spend money on the barrel manufacturer. That will get you accuracy, not length.

Accuracy isn't determined by barrel length. Velocity is.

What barrel profile and manufacturer, how the rifle is built, how you shoot, what ammo you use, etc. all will play a larger role in accuracy.
