Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack Review

Let’s Talk About Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack

The Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack is a seemingly small, but incredibly vital, component often overlooked until you desperately need it. Manufactured by Precision Reflex, these stainless-steel shims are designed to provide precise alignment adjustments for various firearm applications. This simple pack can be a lifesaver when installing muzzle devices, gas blocks, or other accessories, ensuring optimal performance and preventing damage.

I’ve spent countless hours on the range and in the field, and proper alignment is paramount for accuracy and reliability. I was recently fighting a canted muzzle brake installation on my AR-15 build and needed a solution to perfectly time the brake. Other options existed, but the varied thicknesses and stainless steel construction of the Precision Reflex shims appealed to me.

Upon receiving the Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack, my initial impression was one of relief. The shims are neatly organized within a small bag. The stainless-steel material looked clean and free of burrs, suggesting quality machining.

Compared to using crush washers (which are a one-time-use solution and can sometimes over-crush), or the imprecise method of tightening until “it looks right,” the Precision Reflex shims offer a fine-tuned and reusable option. They seemed superior to polymer shim sets I’d seen that could be prone to deformation under heat and pressure. My initial excitement was high, as this promised to solve a frustrating issue with precision and ease.

Real-World Testing: Putting Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack to the Test

First Use Experience

My initial testing ground was my home workshop, where I was determined to correctly time that pesky muzzle brake. The process was straightforward: thread the brake on, note the degree of misalignment, and then experiment with different combinations of shims until the brake was perfectly aligned. The variety of shim thicknesses allowed me to achieve a precise fit, something impossible with a crush washer alone.

Working in a relatively clean environment, I didn’t encounter any extreme conditions. However, the stainless steel construction gave me confidence that these shims would hold up well even in wet or dirty environments. The ease of use was remarkable; no special tools or expertise were required, just a bit of patience and trial-and-error.

The only surprise was how little shim thickness was actually needed to make a significant difference in alignment. I had initially anticipated needing to stack several shims, but a single .003″ shim was enough to perfect the timing in one case.

Extended Use & Reliability

After several weeks of use and multiple muzzle device swaps on different firearms, the Precision Reflex 1/2 inch Internal Diameter Spacer Shim Pack has held up admirably. There are no signs of wear and tear on the shims themselves, even after repeated use and torquing. The stainless-steel construction has proven resistant to corrosion.

Cleaning is simple; a quick wipe-down with a cloth is all that’s needed. Compared to previous experiences with imprecise alignment methods (leading to poor accuracy and potential damage to threads), the Precision Reflex shims have been a game-changer. They consistently provide a precise, repeatable, and reliable solution.
