What’s Included in the P80 Rail Kit

Each Polymer 80 Rail Kit from AIM Arms comes as a complete package, providing all the components necessary for front and rear support in your PF-Series pistol frame. These essential parts have been engineered to tight tolerances and manufactured using high-quality materials to ensure long-lasting performance and structural integrity.

✅ Locking Block Rail System (Front)

This two-part system provides crucial front-end support and stability for the slide and barrel. It also helps align the barrel during recoil, maintaining accuracy and preventing wear. The modular design makes it easier to drill, fit, and install, whether you're assembling a compact frame or a full-size build.

✅ Rear Rail Module

Serving as the rear anchor point for your slide, this component ensures proper function of the trigger mechanism and slide movement. It installs in the rear of the frame to provide balance and structural cohesion throughout the entire assembly.

✅ Fitting Pins (2)

The kit comes with two high-strength steel pins: one for securing the front rail and one for the rear. These pins ensure all parts remain tightly in place during use and over time, even under repeated recoil.

Compatibility: Choose the Right RAIL KIT for Your PF-Series Frame

To ensure proper fitment and function, it's important to select the correct rail kit based on your specific PF-Series frame model. The P80 Rail Kit is not a one-size-fits-all product; rather, it's designed to match the unique dimensions and pre-formed pin holes of each frame style.

Here’s a breakdown of supported models and what each kit includes:

🔷 G17 PF940V2/CL Full Size / Compact Longslide

• Kit Includes: Locking Block Rail System (Front), Rear Rail Module, 2 Pins

Benefits of Upgrading with the P80 Rail Kit

Upgrading your PF-Series build with a quality rail kit is one of the most critical steps in ensuring reliable, accurate, and safe firearm function. Here are some of the key benefits:

✅ Improved Precision and Alignment

Poor alignment between the slide and frame can cause malfunctions and degraded accuracy. With this kit, you can achieve optimal alignment between slide, barrel, and trigger system—every time.

✅ Enhanced Durability

The rails are manufactured using high-strength metal alloys, ensuring they withstand the stresses of recoil and wear over time. You can expect thousands of rounds without compromise to function or safety.

✅ Ease of Installation

Thanks to the modular split-rail design, you’ll find the installation to be intuitive, even if you’re working on your first 80% build. Minimal tools are required, and the parts slide into place using existing guide holes.

✅ Modular Design for DIY Enthusiasts

Whether you’re building a pistol for range use, competition, or personal protection, the modularity of the PF-Series system combined with this rail kit allows you to fully customize the firearm to your exact specifications.

✅ Cost-Effective Customization

Why pay a gunsmith for basic assembly when you can do it yourself with high-quality parts? This kit gives you professional-grade performance at a fraction of the cost of a pre-built firearm.
