How AR Barrel Length Affects Velocity (chart)

[DogBonz]

Have you ever wondered how AR barrel length affects velocity? I know that there has been much debate on this topic, so here you go.

This is a table showing different barrel lengths and how they affect velocity in AR15's. It has a bunch of different barrel lengths as well as bullet types and weights.

Check it out.

P.S. I'm sorry, but the first page is actually page 2. If you print them out, you can put it in order.

Awesome, thx. I'm probably one of the last guys shooting 20" 1:12 & 55grs! Great info.

yup

I thought that it would be a nice reference for folks to have.

That's wierd, the last two inches give a greater gain than the previous 4 inches?
