The Anderson Manufacturing AR-15 A3 upper receiver with forward assist gives you a solid, mil-spec platform for building or upgrading your rifle. Built from 7075 T6 aluminum and CNC machined to Military Specifications, this forged upper is engineered for durability and reliable performance on the range or in the field. Whether you're assembling a new AR-15 from scratch or swapping uppers for a different caliber, Anderson's multi-caliber design plays well with the full spectrum of standard AR-15 platform cartridges—making it a practical choice for shooters who like flexibility in their builds.
The Type 3 hard anodized black finish resists corrosion and handles rough use without showing wear too quickly. This is a no-frills, workhorse receiver: no marketing fluff, just forged aluminum and precision machining that respects both your budget and your build. The forward assist adds one more layer of reliability during firing, a feature that appeals to hunters, competition shooters, and anyone who values the A3 profile for its proven track record.
Anderson Manufacturing has built a reputation for delivering solid AR components at honest prices, and this upper receiver reflects that philosophy. It's the kind of part that lets you focus on the caliber, barrel, and furniture that match your actual shooting plans—not on overpaying for aesthetics you don't need.
| Material | Forged 7075 T6 Aluminum |
| Profile | A3 with Forward Assist |
| Finish | Type 3 Hard Anodized Black |
| Caliber Compatibility | Multi-caliber (AR-15 platform, excluding large bore calibers) |
| Manufacturing Process | CNC Machined |
This upper is multi-caliber compatible with all standard AR-15 platform cartridges. The main exclusion is large bore calibers that fall outside the typical AR-15 envelope—stick with common center-fire rounds like 5.56 NATO, .223 Rem, .300 Blackout, 6.5 Grendel, and similar AR-15 offerings, and you're good to go.
This upper is forged from 7075 T6 aluminum and CNC machined. Forged construction offers excellent strength-to-weight performance and is the standard in mil-spec AR-15 uppers.
Yes—this is a standard AR-15 A3 upper receiver and will mate with any standard AR-15 lower receiver. Assembly is straightforward and requires no special tools or gunsmithing.
Type 3 hard anodize is a durable protective coating that resists corrosion, scratching, and wear. It's the standard finish on mil-spec AR-15 uppers and holds up well to field use and cleaning.
