Aero Precision Slick Side Upper Receiver - Assembled
Should you need an Aero Precision product we don't carry, we recommend going directly to the great folks at Aero Precision.
This Aero Precision Slick Side Upper Receiver is fully assembled with the dust cover already installed. This upper receiver does not have a forward assist. Forged from 7075-T6 aircraft aluminum and then hard coat anodized to mil spec. Includes M4 feed ramps. Fully compatible with all mil spec AR15/M16/M4 components. T-marks are laser engraved on the top rail and look great against the rich black anodized finish. Aero Precision is well known for their high quality AR15 parts including AR15 upper receivers. This Aero Slick Side Upper is a favorite for many light weight AR15 builds.
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.

About Aero Precision
At Aero Precision we're known for two things: superior engineering & machining, and the ability to get the customer what they need, when they need it. Our products have been recognized across the country by members of the military and law enforcement communities for a simple fact - they work better.
Our goal is simple: technical perfection
Aero Precision’s roots are deeply tied to aerospace, and our drive for clean, perfect engineering and machining stems from that. When you’re building something that will fly in the air, there is no margin for error. We take that same approach in the firearms industry. Not every manufacturer will have razor thin tolerance levels. Not every manufacturer will personally oversee the development, design and machining of every part that comes off the line. We’re not every manufacturer.
State of the art in every way
Manufacturing a great receiver isn’t just about what the end product looks like. It’s about what it feels like, how it works, how it handles and performs. To ensure that each and every one of these elements meets the mil-spec standard, we look at the process from which the product was created at a holistic level. We push the boundaries of manufacturing and challenge the status quo by constantly looking for new ways to use, develop or evolve existing processes. By personally designing and engineering state of the science tooling in-shop, we’re able to leverage the latest machine tool technologies to provide you with components of the highest quality.
Our investment, your benefit
Rail guided robotic equipment, new horizontal machining centers with sophisticated monitor devices and hydraulic tooling to ensure consistent loading. These pieces of equipment are standard in our shop and exemplify the dedication we have to investing in our work. We engineer total process control. We have made and continue to make the upfront investment to produce the highest quality components day after day. Are there cheaper ways to build the same product? Sure. Would you as the end user see a difference in the way it works? You better believe it. Better engineering builds better components. It’s just that simple.
OEM Provider - A reputation you can count on
We don’t settle for anything less than perfection. And we don’t say that lightly. As a key manufacturer for many OEM suppliers, we know that it’s not just about the quality of the part we provide, it’s our ability to get the right product out the door at the right time. We’re committed to providing our OEM customers with the exacting attention to detail you’ve come to expect from Aero Precision. We don’t expect anything less. Neither should you. Being an OEM supplier means that we’re putting more than just our reputation on the line, we’re putting yours out there as well. We understand that risk and know what it takes to build a high-quality relationship in addition to a high-quality product. By working closely with you we build a partnership throughout the entirety of the project from design to engineering and final execution. This partnership based on trust, integrity and competence is what gives our customers the end results they want and need.
Below: This AR15 was built as a pistol using an Aero Precision Upper with no forward assist, often called a Slick Side Upper instead of the more common standard Aero Precision Upper. Sporting Aero M-LOK handguards and an 11.3" BA Hanson barrel. Pistol brace is the rugged SBA3 from SB Tactical and a Black Nitride Toolcraft BCG rides inside. Count on bet-your-life reliability when quality AR15 parts are put together properly.
Below: The lack of a forward assist button reveals this AR-15 was built with a Slick Side Upper, this one manufactured by Aero Precision in Tacoma WA. The result is a lighter, more snag proof weapon.
