First Impressions of Aero Precision ATLAS AR15 Shim Pack
The Aero Precision ATLAS AR15 Shim Pack might seem like a small, insignificant product, but for anyone who’s built or customized AR-15s, it’s an essential piece of the puzzle. These shims are designed specifically for Aero Precision‘s ATLAS (Advanced Tactical Locking Attachment System) R-ONE and S-ONE handguards, ensuring a secure and properly aligned fit to the upper receiver. After facing repeated alignment issues with aftermarket handguards, I decided a reliable shim pack was a must-have for my workbench.
I’ve been building AR-15s for over a decade, and I’ve encountered countless frustrating moments where handguards just wouldn’t quite line up correctly. Many times, I’ve resorted to makeshift solutions, like cutting up pieces of aluminum cans or using washers. This Aero Precision shim pack promises a more professional and reliable solution.
Upon receiving the Aero Precision ATLAS AR15 Shim Pack, I was immediately impressed by the neat and organized packaging. The shims themselves are cleanly cut and appear to be made of high-quality stainless steel. The material selection gives an immediate sense of durability and precision.
Compared to using generic washers or homemade shims, this pack offered a dedicated solution for Aero Precision handguards. I also considered purchasing individual shims from McMaster-Carr, but the convenience and specified dimensions of this pack ultimately won me over. Honestly, I was relieved to finally have a proper solution to a persistent problem.
Real-World Testing: Putting Aero Precision ATLAS AR15 Shim Pack to the Test
First Use Experience
My first use of the Aero Precision ATLAS AR15 Shim Pack was during a recent AR-15 build for a friend who wanted a lightweight, accurate rifle. I was using an Aero Precision M4E1 upper receiver and an ATLAS S-ONE handguard. Upon installing the handguard, I immediately noticed a slight misalignment with the upper receiver’s rail.
I used the shim pack to carefully adjust the alignment, adding shims until the handguard sat perfectly flush with the receiver. The shims allowed for very fine-tuned adjustments. The result was a seamless top rail and a much more rigid feel to the entire front end.
Extended Use & Reliability
After several months of use, the rifles I assembled using the Aero Precision ATLAS AR15 Shim Pack are still holding up great. The shims haven’t shifted or loosened, and the handguards remain perfectly aligned. This level of reliability provides peace of mind, especially after experiencing the instability of improvised shims in the past.
I haven’t noticed any signs of wear or tear on the shims themselves. Stainless steel is an excellent choice for this application due to its corrosion resistance. Maintenance is non-existent, which is a significant plus. Compared to using homemade shims, the Aero Precision ATLAS AR15 Shim Pack has vastly exceeded my expectations in terms of durability and long-term performance.
