Rifle type AR15 AERO PRECISION M4E1 11.5 '' cal. 223 Rem

Our goal is simple: technical perfection

Aero Precision's roots run deep in aerospace, and our drive for clean, perfect engineering and machining stems from that. When you're building something that's going to fly through the air, there's no room for error. We take the same approach in the firearms industry. Not all manufacturers have very low tolerance levels. Not all manufacturers personally oversee the development, design and machining of every part that comes off the line. We are not all manufacturers.

The state of the art at all levels

There's more to building a quality receiver than just how the end product looks. It's about how it feels, how it works, how it handles and how it performs. To ensure that each of these elements meets the Mil-Spec standard, we look at the product creation process on a holistic level. We push the boundaries of manufacturing and challenge the status quo by constantly seeking new ways to use, develop or evolve existing processes. Through the personal design and engineering of state-of-the-art tooling in our workshop, we are able to harness the latest machine tool technology to provide you with the highest quality components.

Our investment, your advantage

Rail-guided robotic equipment, new horizontal machining centers with sophisticated monitoring devices and hydraulic tooling to ensure constant loading. This equipment is standard in our workshop and illustrates our willingness to invest in our work. We design for total process control. We have made and continue to make the initial investment to produce the highest quality components day after day. Are there cheaper ways to make the same product? Sure. As an end user, would you see a difference in how it works? You better believe it. Better engineering makes better components. It's as simple as that.

An ideal base to develop your custom AR15

It is specified that the caliber is chambered in 5.56x45mm. This implies that it supports the significantly higher pressure of a 5.56x45 mm ammunition compared to a 223 Rem.
