Hello all. I have recently decided to build myself an AR-15 (for the second time ) I have built a lower before, so I'm not worried about that part. The thing is I like the 20" M16 style barrel length as opposed to the short 16" barrel M4 craze that seems to overtake a lot of people.
My question is: is there a significant difference between the two barrel lengths when it comes to velocity and weight/balance of the rifle?
Now the specific information. The upper is being put onto a lower (not sure of which brand yet) but it will have an A2 stock, not a collapsible one. Both uppers have A2 sights and heavy(er) barrels. Also, since the rifle has to comply with NJ laws, both barrels have no bayonet lugs or flash hiders. The only significant differences between the two upper receiver choices is one has a 16" barrel and a carbine length handguard, and the other has a 20" barrel with a rifle length handguard. Thanks for the help guys.
