The improved extractor and firing pin assembly contribute to consistent ignition and extraction. One minor weakness is that the channel liner requires specialized tools for installation. Overall, the kit meets and exceeds expectations for a drop-in upgrade.

Design & Ergonomics

The Centennial Defense Systems MOD3 Upper Parts Kit is designed to be a direct replacement for factory Glock parts. The stainless steel components offer increased strength and corrosion resistance compared to the original polymer or MIM parts. The kit’s weight is negligible, maintaining the Glock’s excellent balance.

The kit is generally user-friendly, requiring only basic gunsmithing skills for installation. However, as mentioned before, installing the channel liner does require a specialized tool, which adds a slight learning curve for those unfamiliar with Glock assembly.

Durability & Maintenance

The Centennial Defense Systems MOD3 Upper Parts Kit is built to last. The stainless steel construction ensures excellent corrosion resistance and long-term durability.

Given the high-quality materials and construction, this kit should provide years of reliable service. It is a significant upgrade over the original factory parts in terms of longevity and resistance to wear and tear.

Accessories and Customization Options

The Centennial Defense Systems MOD3 Upper Parts Kit focuses primarily on replacing internal components rather than adding external accessories. However, it’s fully compatible with all standard Glock 17 Gen 1-3 slides, barrels, and recoil spring assemblies. Shooters can still customize their pistols with aftermarket sights, slides, and barrels while benefiting from the upgraded internal components of the kit.

The kit itself doesn’t include any specific accessories, but it enhances the reliability and performance of existing Glock 17 accessories and customizations. The stainless steel construction and improved tolerances ensure consistent operation with various aftermarket components.
