What is a Slick Side Upper?
The name “Slick Side” comes from the fact that this upper receiver does not have the traditional forward assist button on the right side. Eugene Stoner, the designer of the AR-15, initially designed his revolutionary rifle without a forward assist button. At the insistence of the U.S. Army, a forward assist mechanism was ultimately designed into the rifle and remains the standard configuration today. The lack of that protrusion gives this upper a more streamlined look hence the nickname “Slick Side”.
If you prefer the traditional upper with a forward assist see the standard Aero Precision Upper
This slick side upper pair well with a Raptor Charging Handle since the right side is clear of the forward assist allowing the ambidextrous Raptor to be used to quickly and easily work the bolt from the right side!
Other popular pairings are Ballistic Advantage barrels and either a Toolcraft Black Nitride BCG or Toolcraft Nickel Boron BCG.
