The UPPER GROUP RESOLUTE 5.7X28MM 16.1in Armor Black Made a Bold First Impression
The UPPER GROUP RESOLUTE 5.7X28MM 16.1in Armor Black isn’t just another AR upper; it’s a statement. Chambered in the increasingly popular 5.7x28mm, this upper promises a flat-shooting, low-recoil experience in a familiar AR platform. The Armor Black finish hints at durability and a serious aesthetic, immediately setting expectations high.
My interest in this upper stemmed from a desire to expand my range capabilities without sacrificing the AR platform I’m intimately familiar with. I was searching for something that offered a different shooting experience, perhaps something flatter and faster than my standard 5.56, yet still retained the modularity and ease of use of an AR-15. The 5.7x28mm caliber has always intrigued me, and the UPPER GROUP RESOLUTE seemed like the perfect way to explore its potential.
Upon unboxing, I was immediately impressed with the fit and finish. The Armor Black coating is evenly applied and appears incredibly durable, offering a reassuringly robust feel. The weight is well-balanced, not feeling overly heavy or cumbersome, which is critical for maneuverability in various shooting scenarios.
Compared to other uppers I’ve handled, particularly those in 5.56 and .300 BLK, the UPPER GROUP RESOLUTE stands out in terms of its sleek profile and perceived quality. I considered a CMMG Banshee in 5.7, but ultimately the AR-specific design of the RESOLUTE won me over, allowing for maximum customization with my existing AR lower and accessories. My initial impression was one of excitement – eager to see if the performance matched the aesthetics.
Real-World Testing: Putting UPPER GROUP RESOLUTE 5.7X28MM 16.1in Armor Black to the Test
First Use Experience
My initial testing of the UPPER GROUP RESOLUTE 5.7X28MM 16.1in Armor Black took place at my local range, a mix of indoor and outdoor bays. I tested it in varying weather conditions, from a dry sunny day, to a slightly drizzly afternoon. I wanted to evaluate its performance with a variety of 5.7x28mm ammunition, including Federal American Eagle and FN SS197SR.
The most immediately noticeable characteristic was the incredibly flat trajectory and minimal recoil. Compared to my 5.56 AR, the RESOLUTE felt almost like shooting a .22LR, but with significantly more punch downrange. It was incredibly easy to maintain sight alignment and rapidly engage targets.
There was a slight learning curve adapting to the different ballistics of the 5.7x28mm round. I needed to adjust my holdover at longer ranges, but once I dialed it in, I was consistently hitting steel plates at 100 and 200 yards. No malfunctions occurred, and the upper cycled flawlessly throughout the initial testing.
Extended Use & Reliability
After several months of consistent use, the UPPER GROUP RESOLUTE 5.7X28MM 16.1in Armor Black has proven to be exceptionally reliable. I’ve put hundreds of rounds through it, and it continues to perform flawlessly. The Armor Black finish has held up remarkably well, showing no signs of wear or scratches despite frequent use and handling.
Maintenance is straightforward; a simple wipe-down after each range session is usually sufficient. The bore cleans easily, and the bolt carrier group is easily accessible for thorough cleaning and lubrication. Compared to some of my other firearms that require more meticulous maintenance, the RESOLUTE is surprisingly low-maintenance.
This upper has far exceeded my expectations. It’s more accurate, more reliable, and more enjoyable to shoot than I initially anticipated. It has become my go-to option for range days and varmint hunting where permissible.
