SilencerCo SCO15 AR-15 Stripped Upper Receiver Review

First Impressions of SilencerCo SCO15 AR-15 Stripped Upper Receiver

The SilencerCo SCO15 AR-15 Stripped Upper Receiver promises a premium foundation for any AR-15 build. Marketed as a precise, high-quality component, it aims to match the aesthetics and performance of SilencerCo’s popular SCO15 lower receiver. This billet upper boasts 7075 aluminum construction and a Type III hard anodized finish, suggesting ruggedness and longevity.

I was in the market for an upper receiver to complete a dedicated suppressor host build. My aim was to achieve maximum parts compatibility and durability. After hearing about the tight tolerances of the SilencerCo lower, I thought pairing it with the SCO15 AR-15 Stripped Upper Receiver would be a perfect match.

The unboxing experience was fairly standard. The receiver came wrapped in protective paper. My initial impression was positive, noting the clean lines and the deep black anodizing. The weight felt substantial, suggesting a robust build.

I considered options from Aero Precision and Bravo Company Manufacturing (BCM) due to their reputations for quality. However, I decided on the SilencerCo SCO15 AR-15 Stripped Upper Receiver because I already owned the matching lower, and the promise of a perfect fit was appealing. I hoped the matched set would deliver enhanced accuracy and aesthetics.

Initially, I was cautiously optimistic. The finish appeared flawless, but I was aware of online reviews mentioning color mismatch issues with the lower. I was eager to see how it would perform and if it lived up to the hype.

Real-World Testing: Putting SilencerCo SCO15 AR-15 Stripped Upper Receiver to the Test

First Use Experience

I first tested the SilencerCo SCO15 AR-15 Stripped Upper Receiver at my local outdoor shooting range. The build included a 16-inch Faxon barrel, a Lantac Dragon muzzle brake, and a Geissele MK4 handguard. I wanted to ensure functionality with a variety of high-end components.

The weather was mildly dusty, with temperatures hovering around 75 degrees Fahrenheit. I put roughly 200 rounds through the rifle, focusing on accuracy and cycling reliability. It handled both .223 and 5.56 NATO ammunition without a hitch.

The upper installed easily onto my existing SilencerCo lower. Everything seemed aligned. I immediately appreciated the solid feel and the smooth cycling. There were no apparent issues during the initial range session.

However, I did notice a slight color variation between the upper and lower receivers, although not as drastic as some online reviews had suggested. This was a minor disappointment.

Extended Use & Reliability

After several months of use, including multiple range trips and a carbine course, the SilencerCo SCO15 AR-15 Stripped Upper Receiver has held up well. I have now put around 1500 rounds through the rifle. There have been no malfunctions related to the upper receiver itself.

The hard anodized finish shows minimal signs of wear, primarily around the ejection port. The internals remain clean and well-lubricated. Maintenance involves regular cleaning and lubrication after each range session.

Cleaning is relatively straightforward. I typically use a standard AR-15 cleaning kit with bore solvent and CLP. The finish is resistant to most solvents, making cleanup quick.

Compared to my previous experience with a standard mil-spec upper, the SCO15 feels more rigid and robust. The tighter tolerances seem to contribute to improved accuracy. I appreciate the added peace of mind knowing I have a durable and reliable component.
