What’s the difference between different barrel lengths?

As a standard guideline, longer barrels shoot projectiles quicker, more remote and more precisely than shorter ones. Longer barrels are likewise heavier and harder to move. Shorter barrels are increasingly appropriate for nearer commitment because of their length and lighter weight, yet they are not as precise at long range. Long range barrels are commonly 18 or 20 inches in length, while short barrels are 14.5 inches or shorter. 16 inch barrels will in general be a decent universally handy length.
