First Impressions of Centennial Defense Systems MOD5 Upper Parts Kit for Gen 1-3 Glock 17 w/Flat Face Button Head Screw
The Centennial Defense Systems MOD5 Upper Parts Kit for Gen 1-3 Glock 17 w/Flat Face Button Head Screw promises a comprehensive solution for upgrading or completing your Glock 17 build. As someone who’s spent years tinkering with Glocks, from competition builds to duty weapon enhancements, I’m always eager to see what new parts and kits the market offers. Does this kit provide a tangible upgrade in performance and reliability, or is it just another collection of potentially problematic aftermarket parts?
My primary motivation for seeking out this kit stemmed from a desire to refresh an older Gen 2 Glock 17 that had seen better days. The original internals were showing wear, and I wanted a cost-effective way to breathe new life into it without breaking the bank on a complete slide assembly. I’ve always believed a well-maintained and upgraded Glock can be a supremely reliable and accurate pistol.
Upon opening the package, I was immediately drawn to the stainless steel components. The finish appeared clean and well-machined, and the inclusion of the flat face button head screw for the channel liner was a welcome addition. It’s always the small details that can make or break a build. Compared to similar kits from Lone Wolf Distributors and Brownells, this Centennial Defense Systems kit seemed to offer a more streamlined and complete package at a competitive price point, which ultimately swayed my decision. My initial excitement was tempered by a healthy dose of skepticism, as I’ve learned that looks can be deceiving, and the true test lies in performance.
Real-World Testing: Putting Centennial Defense Systems MOD5 Upper Parts Kit for Gen 1-3 Glock 17 w/Flat Face Button Head Screw to the Test
First Use Experience
I tested the Centennial Defense Systems MOD5 Upper Parts Kit for Gen 1-3 Glock 17 w/Flat Face Button Head Screw at my local outdoor range, under relatively mild conditions – sunny, around 70 degrees Fahrenheit. My focus was primarily on functionality and reliability with a variety of ammunition types, from standard 115-grain FMJ to 124-grain +P hollow points. The installation process was straightforward, though I did appreciate having a Glock armorer’s tool on hand to ensure proper seating of some of the smaller components.
The first few magazines cycled without issue, but I did experience a couple of failures to extract within the first 100 rounds. This initially raised concerns about the extractor, but after a thorough cleaning and lubrication, the issue seemed to resolve itself. After this initial hiccup, the pistol ran flawlessly for the remainder of the session, which spanned roughly 300 rounds.
Extended Use & Reliability
After several weeks and approximately 1000 rounds fired, the Centennial Defense Systems MOD5 Upper Parts Kit for Gen 1-3 Glock 17 w/Flat Face Button Head Screw has proven surprisingly reliable. I’ve noticed no further failures to extract or any other malfunctions, even after intentionally neglecting cleaning for a couple of range sessions to simulate more demanding conditions. The stainless steel components show minimal signs of wear, and the finish has held up remarkably well despite regular use.
Maintenance has been simple, requiring only standard Glock cleaning procedures. Compared to previous experiences with aftermarket Glock parts, this kit has significantly outperformed cheaper, less reputable options in terms of both reliability and durability. The Centennial Defense Systems kit has restored my confidence in the Gen 2 Glock 17.
