Griffin Armament M4SD Hammer Comp Review

Let’s Talk About Griffin Armament M4SD Hammer Comp

The Griffin Armament M4SD Hammer Comp is a muzzle device designed to interface with the Griffin Armament M4SD series of silencers. This comp aims to reduce recoil and muzzle rise while providing a durable mounting solution for your suppressor. I decided to give it a try after consistently hearing positive feedback about its performance and build quality, especially regarding its compatibility with the Griffin Armament QD Blast Shield.

I had been searching for a muzzle device that could effectively tame the muzzle rise of my AR-15 while also serving as a solid suppressor mount. Many compensators on the market are overly aggressive, creating excessive concussion. The M4SD Hammer Comp intrigued me with its promise of balanced performance.

Upon unboxing, the Griffin Armament M4SD Hammer Comp impressed me with its solid construction. The black oxide finish looked clean and durable, and the weight felt substantial without being overly heavy. The included shim set and over-travel stop washer were a welcome addition, showing attention to detail.

I considered other muzzle devices like the Strike Industries JCOMP and the SureFire Warcomp. Ultimately, I chose the Griffin Armament M4SD Hammer Comp because of its compatibility with Griffin Armament suppressors and QD Blast Shield, as well as its reputation for effective recoil reduction without excessive side blast. My initial impression was excitement; the device felt like a quality piece of equipment that would perform as advertised.

Real-World Testing: Putting Griffin Armament M4SD Hammer Comp to the Test

First Use Experience

I first tested the Griffin Armament M4SD Hammer Comp at an outdoor shooting range. The weather was clear and dry, providing ideal conditions for assessing its performance. I mounted it on my 16″ AR-15 chambered in 5.56 NATO, using a variety of ammunition types, including M193 and heavier 77-grain rounds.

The difference in recoil and muzzle rise was immediately noticeable. The Hammer Comp effectively mitigated muzzle flip, allowing for faster follow-up shots. The slotted compensating features worked as advertised, maintaining stability.

The installation was straightforward using the included shims to achieve proper timing. No issues arose during the initial range session. I was pleased with the initial performance and eager to test it further.

Cleaning the Hammer Comp is a simple process. A quick scrub with a solvent and brush removes carbon buildup effectively. I haven’t experienced any issues with loosening or requiring re-timing, indicating a robust design.

It outperforms a standard A2 flash hider significantly in terms of muzzle control and offers a more pleasant shooting experience than some overly aggressive muzzle brakes. This comp maintains its high-performance capabilities.
