Griffin Armament Griffin Shim Set Review

Let Me Tell You About the Griffin Armament Griffin Shim Set

As someone who’s spent over a decade wrestling with gear in every conceivable environment – from the sterile precision of a lab bench to the unforgiving grit of outdoor expeditions and the organized chaos of a workshop – I’ve developed a keen eye for what works. The Griffin Armament Griffin Shim Set is a deceptively simple component, but it plays a critical role in the proper installation of muzzle devices. My own need for a reliable method to precisely time a muzzle brake on a precision rifle build prompted this deep dive. I’d tried generic shims before, and the frustration of trying to achieve perfect perpendicular alignment was a constant nuisance. While I briefly considered a few other universal shim packs, the specific engineering and reputation of Griffin Armament made their set the clear choice for this build. My initial impression upon opening the small package was one of quiet competence; the metal felt substantial, and the individual pieces were neatly presented, hinting at a thought-out solution.

Real-World Testing: Putting Griffin Armament Griffin Shim Set to the Test

First Use Experience

My initial test occurred on my workbench, a controlled environment where precision is paramount. I was fitting a Griffin Armament muzzle brake to a custom bolt-action rifle chambered in .308. The need for precise alignment isn’t just aesthetic; it’s crucial for suppressor compatibility and overall system performance. I found the shims remarkably intuitive to work with. The standard dimensions allowed for immediate integration into the muzzle threading, and the tactile feedback when seating the muzzle device was clear. There were no surprising quirks, just a straightforward path to achieving the desired torque and alignment. The user feedback mentioning their utility across multiple rifles also resonated, hinting at a well-dimensioned set.

Extended Use & Reliability

Since that initial build, this particular shim set has seen action on a couple of other rifle projects, including a direct-impingement AR-15. It’s been exposed to the usual workshop dust and the occasional fingerprint smudges during reconfigurations. Durability hasn’t been an issue; the stainless steel construction has resisted any significant wear, and they maintain their precise dimensions even after repeated installation and removal. Maintenance is essentially non-existent, beyond a quick wipe-down to remove any residue, which is a testament to their straightforward design. Compared to the flimsy, inconsistently sized shims I’ve encountered from less reputable sources, this Griffin Armament offering feels like a premium component, delivering consistent results without fuss.

Breaking Down the Features of Griffin Armament Griffin Shim Set

Specifications

The Griffin Armament Griffin Shim Set is designed to be the essential tool for achieving perfect perpendicular alignment of Griffin Armament muzzle devices with the barrel’s thread shoulder. This kit includes an assortment of stainless steel shims, crucial for precise timing. The primary function of these shims is to create a perfectly flat and perpendicular surface, ensuring that the muzzle device seats correctly against the barrel. This level of precision is particularly vital for suppressor mounting applications, where even minor misalignment can lead to baffle strikes or compromised performance. The user feedback hinting at “different sizes and plenty of them” suggests a generous and versatile offering, allowing for adjustments across various barrel and muzzle device combinations. The stated price of $9.99 for this crucial set represents excellent value, especially when considering the potential damage caused by improperly timed muzzle devices.

Performance & Functionality

The core function of this shim set is to enable the precise timing of muzzle devices. In this regard, it performs exceptionally well. It provides the necessary tactile and visual cues to achieve perfect perpendicularity, which is its sole, yet critical, purpose. The shims themselves are thin enough to allow for fine adjustments, yet robust enough to withstand the torque applied during installation. The main strength is their simplicity and effectiveness; they do exactly what they are designed to do without any extraneous features. A potential weakness, as noted in one user’s feedback, could be the outer diameter; while designed for Griffin Armament products, compatibility with all muzzle threads from all manufacturers might vary. However, for their intended application, they are flawless.

Design & Ergonomics

The design of these shims is, by necessity, minimalist. They are thin, circular pieces of stainless steel, typically with an inner diameter that fits the barrel threads and an outer diameter that interfaces with the muzzle device. The material, stainless steel, provides excellent corrosion resistance and durability. The finish is typically a smooth, matte surface that doesn’t detract from the firearm’s aesthetics. Ergonomically, there isn’t much to discuss beyond their function; they are small, flat components handled with fingertips or a set of precision tweezers. Their effectiveness lies in their precise manufacturing, ensuring a consistent interface.

Durability & Maintenance

As mentioned, the Griffin Armament Griffin Shim Set is built from stainless steel, a material known for its resilience. Under normal installation and removal cycles, these shims are designed to last. They are not a consumable item and should retain their integrity for the lifetime of the firearm or until a different muzzle device is installed. There are no moving parts to wear out, and their simple form factor means there are no complex maintenance requirements. A simple wipe-down with a cloth to remove any oil or debris is all that’s typically needed to keep them in pristine condition. The only real concern would be losing them, given their small size, which is a common issue with many small firearm components.

Accessories and Customization Options

The Griffin Armament Griffin Shim Set is, by its nature, a standalone component designed for a specific task. It doesn’t typically come with additional accessories. However, the “set” itself implies a collection of shims of varying thicknesses, providing the “customization” needed to achieve perfect timing. This variety is key; it allows the user to fine-tune the alignment by stacking or selecting the appropriate shim thickness. While there aren’t external accessories to consider, the compatibility of the inner and outer diameters with Griffin Armament muzzle devices and barrels is the primary “fit” to be aware of.

Pros and Cons of Griffin Armament Griffin Shim Set

Who Should Buy Griffin Armament Griffin Shim Set?

This shim set is ideal for anyone installing Griffin Armament muzzle devices, particularly on precision rifles where accurate alignment is paramount. It’s a must-have for builders and gunsmiths who value proper function over guesswork. If you are fitting a Griffin Armament muzzle brake or suppressor mount, this set ensures the job is done correctly and safely.

Those who should consider skipping this purchase are individuals who are buying a Griffin Armament muzzle device that already includes a shim set. Additionally, if you are not using Griffin Armament products, you might need to research the compatibility of the shim’s outer diameter with your specific barrel and muzzle device combination, as one user found it slightly larger than their barrel’s OD. For optimal use, consider having a small, dedicated container or magnetic tray to prevent losing these crucial, albeit small, components.

Conclusion on Griffin Armament Griffin Shim Set

The Griffin Armament Griffin Shim Set is a testament to the fact that sometimes, the simplest components can be the most critical for overall system integrity. For its intended purpose – the precise alignment of Griffin Armament muzzle devices – it performs flawlessly. The stainless steel construction ensures longevity, and the inclusion of a sufficient quantity of shims provides the flexibility needed for a perfect fit. At $9.99, the value proposition is outstanding, especially when you consider the potential cost of misaligned components or damaged suppressors.

While it’s important to note that Griffin Armament muzzle devices typically include a shim set, for any builder who needs to time a Griffin Armament muzzle device, this set is a small investment that pays dividends in accuracy and peace of mind. I would absolutely recommend this shim set to anyone working with their muzzle devices, confident that it will facilitate a professional and secure installation every time.
