If both barrels are identical, only difference being length, then not really. Factory ammo is about 100-150fps difference between a 16" and 20" Bushmaster factory uppers. So 50-75fps on blunt, low b.c. bullets, not much of difference. Handloads will get you a little more. Now, if you compare something like a 16" Bushmaster factory upper to, say, an 18" Tromix, then you gain a bit. The Tromix matches or slightly beats a 20" Bushmaster factory upper.
