9mm Complete Upper Receivers

Over the past 20 years, pistol caliber carbines (PCC) like 9mm AR-15 conversions have gained significant popularity. People love 9mm AR-15s because they're easy to handle and take less expensive ammunition, so you can spend all day plinking for less.

Whether you're starting from scratch or upgrading your favorite firearm, our 9mm complete upper receivers are a quick and convenient way to create an exceptional 9mm AR-15.

Brands We Carry

At Wing Tactical, we put a lot of time and effort into choosing the products we offer our customers. We carry only top-quality parts and accessories from the industry's leading brands. As you browse our collection of 9mm AR-15 uppers, you'll find options from trusted names like:

  • Kaw Valley Precision
  • Aero Precision

Barrel Length Options Available

Your AR-15 barrel length has a significant impact on both the velocity and accuracy of your shots. Generally speaking, a longer barrel allows you to achieve increased accuracy and maximum power over longer distances, while shorter barrels are lighter and more maneuverable in confined areas, making them excellent for home defense applications.

A 16-inch barrel length is often the most popular option for standard AR-15 builds. For 9mm builds, the barrel length is all about your personal preference and purpose. At Wing Tactical, our 9mm complete uppers are available in the following lengths:

  • 4.5-inch
  • 5.5-inch
  • 8.5-inch
  • 11-inch
  • 16-inch

It's also worth noting that barrels 16 inches or greater in length are subject to less regulation and do not require a Class III tax stamp from BATFE (The Bureau of Alcohol, Tobacco, Firearms and Explosives). Depending on whether the firearm is built as a rifle or pistol, shorter barrel lengths may fall under the National Firearms Act and require registration as a short-barreled rifle (SBR).

9mm Upper FAQs

Can these 9mm uppers be installed with any lower receiver?

Our 9mm AR-15 uppers are compatible with any dedicated 9mm lowers. While there are conversion kits that allow you to convert a standard AR-15 lower to make it compatible with a 9mm upper, these setups tend to be flawed and vulnerable to malfunctions.

To maintain a safe and accurate firearm, you'll want a dedicated 9mm lower that ensures the right fit with your new upper receiver.

What parts are included in the 9mm complete uppers?

Most complete 9mm upper sets include an upper receiver, barrel and handguard. These sets also typically include a muzzle device like a compensator or flash hider. Some complete uppers — like our Kaw Valley Precision options — include a bolt carrier group and charging handle as well.

Complete uppers are quick and convenient to install because they already include everything you need — you just have to attach your upper to a compatible lower, and you're good to go.

What handguard style is used on these complete uppers?

Our current options for 9mm complete uppers come with M-LOK handguards, so any accessories or parts you purchase for your 9mm build should be M-LOK compatible. Though less seamless, rail converters are also available so you can add sections of Picatinny rail to your handguard if needed.
