I'm planning to buy a new Bushmaster AR15 type rifle soon and need to choose a barrel length. I'm stuck between 16 and 20 inch. I'm leaning toward the 20" because I'm not planning to be kicking down doors or anything like that, and a longer barrel should give more velocity. But a friend of mine is telling me to get the 16" because it's lighter and the 4" don't make much difference in velocity. Any input?
BTW the rifle will be used for self defense purposes.
