The Alexander Arms Tactical Complete Upper 6.5 Grendel 16″ Black Cerakote Aluminum Receiver M-LOK Handguard for AR-15 Made a Bold First Impression
The Alexander Arms Tactical Complete Upper 6.5 Grendel 16″ Black Cerakote Aluminum Receiver M-LOK Handguard for AR-15 is more than just another AR-15 upper; it’s a precision-engineered tool built for accuracy and reliability. This complete upper receiver assembly chambered in the potent 6.5 Grendel cartridge promised to be a game-changer. I’ve been building and customizing AR-platform rifles for years, but the allure of the 6.5 Grendel’s flat trajectory and superior ballistics at extended ranges has always been strong.
I had been searching for a solution to improve my mid-range hunting capabilities. Specifically, I needed an upper receiver that could deliver consistent accuracy out to 600 yards for ethically harvesting game. The Alexander Arms reputation for quality and the promise of a complete, ready-to-install upper sealed the deal.
Upon unboxing, the first thing that struck me was the fit and finish. The Black Cerakote coating looked impeccable, providing a uniform and durable layer of protection. The M-LOK handguard felt solid and offered plenty of real estate for accessories. It exuded quality craftsmanship. The weight felt appropriate for a 16-inch barreled upper, not too heavy to be unwieldy but substantial enough to inspire confidence.
I considered uppers from Bravo Company Manufacturing (BCM) and Daniel Defense, both respected names in the AR world. While those are excellent choices, they often require additional parts and assembly. This Alexander Arms complete upper offered a seamless integration with my existing AR-15 lower receiver. I was hoping for ease of use and out-of-the-box accuracy.
My initial impression was one of excitement. This upper felt like a significant upgrade. The promise of enhanced accuracy and ballistic performance with the 6.5 Grendel cartridge was incredibly enticing. I couldn’t wait to get it to the range.
