Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″ Review

The Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″ Made a Bold First Impression

After a decade of squeezing triggers and tinkering with tactical setups, I thought I’d seen it all when it comes to AR-15 accessories. Then I stumbled upon the Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″, a device promising to tame the recoil of my beloved AR. Manufactured by Surefire, known for their premium weapon lights and suppressors, this muzzle brake promised performance without breaking the bank.

My primary AR, a Ruger AR-556, is a fun range toy, but it could be a bit snappy, especially during rapid-fire drills. I was chasing flatter shooting, faster follow-up shots, and a bit more control without venturing into the expensive world of adjustable gas blocks and custom tuning. This brake seemed like a simple, effective solution.

The Surefire PROCOMP556 ProComp arrived in a no-frills package, just the brake itself. Holding it for the first time, I was impressed by the weight and the flawless black Melonite finish. The steel felt incredibly solid, promising durability. Compared to cheaper, no-name brakes I’d seen, the Surefire exuded quality. I also considered a Strike Industries J-Comp and a BattleComp, but the Surefire’s reputation for minimizing side blast, while still offering recoil reduction, ultimately won me over.

I was cautiously optimistic upon initially unboxing the Surefire PROCOMP556. It felt like a quality piece, but muzzle brakes can be hit or miss. I’ve seen some that are all bark and no bite and others that make you feel like you’re standing next to a howitzer. I hoped this Surefire would be a sweet spot.

Real-World Testing: Putting Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″ to the Test

First Use Experience

My first trip to the range with the Surefire PROCOMP556 installed was on a blustery day, perfect for assessing its performance in less-than-ideal conditions. I primarily shot from a bench, focusing on controlled pairs and rapid-fire drills, but also spent some time shooting prone to see how much dust it kicked up. The difference was immediately noticeable. Muzzle rise was significantly reduced, allowing for much faster follow-up shots.

The felt recoil was also noticeably lessened. It transformed the AR from feeling a bit harsh to something much more manageable. The Surefire PROCOMP556 did exactly what it claimed. The concussion wasn’t bad at all compared to some other brakes I’ve used. I also noticed that even when shooting prone, the brake didn’t kick up nearly as much dust and debris as some others.

There was a slight learning curve. Because the rifle now recoiled straight back with virtually no muzzle climb, I had to adjust my grip and stance slightly to compensate.

Extended Use & Reliability

After several months and hundreds of rounds, the Surefire PROCOMP556 continues to impress. The finish is holding up remarkably well. There are no signs of rust or excessive wear, even after some pretty rough handling. I clean the brake after each range session using a solvent and a nylon brush, and it takes only a few minutes to keep it in top condition.

Compared to my previous experience with other muzzle devices, the Surefire PROCOMP556 is in a different league. It offers a superior balance of recoil reduction, muzzle control, and shooter comfort. It’s a significant upgrade and has definitely improved my shooting experience.

Breaking Down the Features of Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″

Specifications

The Surefire PROCOMP556 ProComp Muzzle Brake M16/M4 5.56mm Steel 2.5″ is specifically designed for 5.56mm AR-15 platforms with 1/2-28 muzzle threads. It’s crafted from US mill-certified steel bar stock, ensuring superior strength and longevity. The brake measures approximately 2.5 inches in length. The Surefire PROCOMP556 ProComp features a black Melonite finish that provides exceptional corrosion resistance and durability.

The patented Impulse Diffusion design is the heart of its performance, effectively minimizing both recoil impulse and muzzle rise. The brake also features blind pilot holes at the 3 and 9 o’clock positions, allowing for fine-tuning of recoil characteristics to suit individual shooting styles or ammunition preferences. These carefully considered specifications translate to improved accuracy, faster follow-up shots, and enhanced shooter control.

Performance & Functionality

The Surefire PROCOMP556 ProComp excels at its primary function: reducing recoil and muzzle rise. This translates to improved accuracy, especially during rapid-fire sequences. The gun tracks straighter and recovers faster. While it can’t be used to mount a Surefire SOCOM suppressor (unlike their SFMB models), its recoil reduction is impressive for the price.

The Surefire PROCOMP556 provides the most recoil reduction and muzzle rise mitigation you can get without a suppressor. The only weakness might be increased noise for those standing next to the shooter. It absolutely exceeded my expectations.

Design & Ergonomics

The Surefire PROCOMP556 boasts a robust design. Its Melonite finish is extremely durable and corrosion-resistant. The weight is noticeable but doesn’t make the rifle feel unbalanced.

The installation of Surefire PROCOMP556 is very easy. Any user with basic gunsmithing tools can easily install the device. The blind pilot holes offer some customization for different shooters.

Durability & Maintenance

Given its construction from US mill-certified steel and its Melonite finish, the Surefire PROCOMP556 is built to last. Regular cleaning with a solvent and a nylon brush is all that’s needed to maintain its performance. I expect it to outlast my rifle.

The Surefire No-Hassle Promise also provides peace of mind for any potential issues. The durable construction means fewer repairs are required.

Accessories and Customization Options

The Surefire PROCOMP556 is relatively straightforward. It doesn’t require any specific accessories for operation. While it cannot mount Surefire SOCOM suppressors, it is compatible with crush washers or shims for proper timing during installation.

The brake’s performance can be fine-tuned by drilling out the blind pilot holes. However, this requires some gunsmithing skills. The device is compatible with most standard AR-15 armorer’s tools.
