First Use Experience

I installed the Centennial Defense Systems MOD2 Upper Parts Kit on my Gen 3 Glock 19 and headed straight to my local outdoor range. The weather was typical for a late summer afternoon: hot, humid, and a slight breeze kicking up dust. My first magazine through the newly built upper was surprisingly smooth. The slide cycled reliably, and the trigger felt crisp and consistent.

The flat face screw, in particular, seemed to improve the overall feel of the trigger pull. I spent the next few hours running various drills. This ranged from slow, deliberate target shooting to rapid-fire exercises to test the kit’s performance under pressure.

I didn’t experience any malfunctions or hiccups. This gave me confidence in the initial reliability of the Centennial Defense Systems MOD2 Upper Parts Kit. I was especially impressed with how well the stainless steel components handled the heat. After several magazines, the slide remained smooth and consistent.

Extended Use & Reliability

After several months and hundreds of rounds, the Centennial Defense Systems MOD2 Upper Parts Kit has proven to be remarkably reliable. I’ve used it in various conditions, from dry and dusty range days to slightly damp outdoor competitions. It has performed flawlessly every time. The finish on the stainless steel has held up exceptionally well.

There are no signs of excessive wear or corrosion. Cleaning and maintenance are straightforward. A quick wipe-down with a quality gun cleaner and lubricant is all it takes to keep everything running smoothly. Compared to other parts kits I’ve used that required constant adjustments and tinkering, this one has been a pleasant surprise.

It has easily outperformed my expectations. I previously experienced issues with aftermarket parts causing feeding problems or inconsistent cycling. The Centennial Defense Systems kit has eliminated those concerns and restored my confidence in my Glock 19’s reliability.
