When you decide to go for that big SOCOM build there are quite a few things to take into consideration. The chamber pressure increases, however, your margin of error decreases and perfection is a must. Therefore, you must get your parts from a company that you can trust. Aero Precision makes the .458 SOCOM AR-15 upper receiver you need to use, so you can trust your build.
There Is No Margin of Error
Aero Precision machines your .458 SOCOM AR-15 upper out of high-grade forged 7075-T6 aluminum that is known for its strength and durability. They maintain extremely tight tolerances, not only for their own high standards, but with your safety in mind. With the pounding that those big rounds are going to dish out, you certainly don’t want your bolt carrier group flopping around inside just any .458 SOCOM upper receiver, you need the best.
Nothing Less Will Do
There are corners to be cut on any build. You can get by with a lot of cheaper accessories like grips, or barricade stops because if those fail you may not bleed. However, when it comes to a critical component such as you .458 SOCOM AR-15 upper, failure is not an option. The good folks at Aero Precision produce a high-quality .458 SOCOM upper receiver, so your weapon will not fail. The end goal for Aero Precision is for you to remain in one piece, satisfied, and coming back to get more parts for years to come. You need to get parts that you can trust from a company you can trust to always provide you with the highest quality parts possible.

The Aero Precision upper receiver has been milled out in the injection port to accommodate the massive .458 round. It is of high quality and craftsmanship, one that you would expect from Aero Precision. I matched the upper receiver with a Aero Precision lower and used a Aero Precision handguard. I am 100% happy with this build project.
