Let’s Talk About Griffin Armament M4SD Silencer Shim Set, Overtravel Stop
Let’s face it: attaching a silencer isn’t always a perfect, drop-in affair. Often, you need a little finesse to ensure proper alignment and prevent damage. That’s where the Griffin Armament M4SD Silencer Shim Set, Overtravel Stop comes in. This seemingly simple kit is crucial for anyone running a Griffin M4SD series silencer, especially when mounting to A2-style muzzle devices.
I stumbled upon this product after experiencing frustrating inconsistencies while switching my Griffin silencer between different AR-15s. Some rifles allowed for perfect, rock-solid mounting, while others exhibited noticeable wobble. It was clear I needed a solution to guarantee proper alignment and prevent potential baffle strikes, which can be catastrophic to both the silencer and the firearm.
Upon unboxing, the Griffin Armament M4SD Silencer Shim Set, Overtravel Stop appears straightforward: a collection of precisely machined stainless steel shims and a hardened steel overtravel stop. The materials felt robust, and the machining quality was immediately evident. The overtravel stop, in particular, felt incredibly solid and well-made.
Compared to generic shim kits I’ve used in the past, the Griffin set is far more tailored to the M4SD system. Generic kits often lack a dedicated overtravel stop, relying solely on shims for alignment. This leaves the silencer vulnerable to being tightened too far, potentially damaging the muzzle device or silencer threads. My initial impression was one of relief. It was apparent that Griffin Armament had considered the nuances of silencer mounting and provided a comprehensive solution.
Real-World Testing: Putting Griffin Armament M4SD Silencer Shim Set, Overtravel Stop to the Test
First Use Experience
My primary testing ground was the range, where I mounted my Griffin M4SD silencer on several AR-15 platforms. Each rifle had either a Griffin M4SD muzzle device or a standard A2 birdcage compensator. The shims were essential, particularly with the A2 devices.
The first test involved mounting the silencer on an A2 birdcage. Without the shims, the alignment was visibly off. Using a combination of the stainless steel shims, I was able to achieve a perfectly perpendicular fit.
The overtravel stop proved invaluable, preventing me from over-tightening the silencer and potentially damaging the threads. With the tab of the overtravel stop positioned at 6 o’clock as instructed, it provided a positive stop, ensuring consistent and secure mounting. The ease of use was remarkable; even a novice can quickly learn to use the shims to achieve proper alignment.
Extended Use & Reliability
After several range sessions and countless suppressor swaps, the Griffin Armament M4SD Silencer Shim Set, Overtravel Stop continues to perform flawlessly. There are no signs of wear or tear on either the shims or the overtravel stop. The stainless steel construction ensures resistance to corrosion, even after exposure to carbon fouling and cleaning solvents.
The kit’s durability is impressive. It’s clear these components are built to withstand the rigors of repeated use. Compared to my previous experience with less robust shim sets, the Griffin kit stands head and shoulders above the rest. It offers a level of confidence and reliability that generic shims simply cannot match. Regular cleaning with a bore brush and solvent keeps the shims in perfect working order.
