AM Complete Upper 223 Rem AR-15 16.25" Barrel with Polymer Handguard

The Anderson Manufacturing AM Complete Upper is a ready-to-shoot 223 Rem AR-15 upper assembly built on a 7075 T6 forged receiver—the backbone of a reliable intermediate rifle. This complete upper arrives with everything you need to pair with a lower receiver: a 16.25" barrel, charging handle, bolt carrier group, and handguard already assembled. Whether you're building your first AR, expanding an existing platform, or setting up a dedicated .223 plinker, a quality complete upper saves you the hassle of sourcing and assembling individual parts while maintaining tight tolerances and proper headspace.

Anderson Manufacturing upper receivers are known for holding their own on the range and in the field. A 7075 T6 forging means you're getting the same aluminum alloy used in aircraft structures—light, strong, and built to handle repeated rounds without flexing or shifting your optics. The 1-in-8 twist rate of the barrel stabilizes a wide range of .223 and 5.56 ammunition, from 55-grain varmint loads to heavier match rounds, making this upper genuinely versatile for hunting, target work, and general use.

The polymer handguard and A2 flash hider round out a proven, no-frills configuration. This isn't a tricked-out competition upper with rail systems and adjustable gas blocks—it's a straightforward, dependable assembly that gets the job done. Pair it with your preferred lower receiver, add optics or iron sights to your taste, and you've got a functional AR ready to shoot.

Frequently Asked Questions

What do I need to complete a rifle with this upper?

You'll need an AR-15 lower receiver to mate with this upper. Once assembled, add your choice of optics or iron sights, a stock, pistol grip, and magazine—then you're ready to shoot.

What ammunition does the 1-in-8 barrel twist stabilize?

A 1-in-8 twist is a jack-of-all-trades rate for .223 and 5.56 ammunition, handling everything from 55-grain varmint and range loads up to heavier match-grade and hunting rounds. You won't be limited to a narrow window of bullet weights.

Is this upper suitable for hunting?

Yes. A 16.25" barrel in .223 Remington with a standard configuration is a practical choice for varmint hunting and small game. Bullet selection and shot placement matter more than the platform itself.

What's included in the box?

The upper receiver, 16.25" barrel, bolt carrier group, charging handle, polymer handguard, and A2 flash hider. You're not buying a bare receiver—everything needed to function is included.
