DefenseReview’s (DR) found that it’s often the little things that can make your life a lot better and/or easier. Assuming it works as advertised, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is one of those products. When it comes to guns heat’s the enemy in a whole bunch of ways, particularly with rifle/carbines, and even more particularly with select-fire rifle/carbines, including those in 5.56mm NATO (5.56x45mm NATO) caliber. Anyway, the Magpul Suppressor Cover – 5.5″ (5.5 inches) is specifically designed to cover 1.5” outer diameter/5.5″-long round cans (silencers/sound suppressors) like the popular Surefire SOCOM556-RC2 muzzle can (silencer/sound suppressor), and it would appear to be very well designed for that purpose.

The the Magpul Suppressor Cover – 5.5″ consists of a “heat-resistant polymer sleeve overlaid onto a raised stainless steel heat shield that mounts directly to the suppressor body with steel clamps” that “minimizes heat transfer to keep external cover temperatures up to 1000 degrees F cooler than the surface of the suppressor and allows cooling airflow across the can. Additionally, it serves as an enhanced thermal insulator and signature reduction device, significantly mitigating mirage distortions to the shooter’s sight picture, reducing the likelihood of impact damage to the suppressor body, and lessening the chance of accidental heat-related injury or damage to personnel or equipment during weapon firing and cool down.” Sounds pretty good.

When you’re involved in a high-speed, low-drag dynamic combat op involving a lot of moving, and perhaps even climbing and/or repelling, the last thing you need is a hot suppressor burning through your clothing or skin. So, why make life any harder than it has to be?

Oh, and the the Magpul Suppressor Cover – 5.5″ even lowers your can’s thermal signature, and attenuates/mitigates the mirage effect on your sight picture. Handy.

The following are Magpul Suppressor Cover – 5.5″ features, straight from the company’s website:

– Extreme temperature protection that mitigates internal suppressor temperatures to safe levels
– Minimizes retained heat, allowing faster cooling than any other suppressor cover technology
– Reduces thermal signature of host firearm
– Mitigates mirage effects in sight picture
– Two stainless steel clamps provide a strong, rigid and reliable interface capable of sustained firing sessions and rough handling
– High temp polymer sleeve withstands brutal suppressor temperatures during extended periods of firing without deterioration
– High strength corrosion resistant stainless steel heat shield

Additional sizes for different can sizes and calibers are supposed to be avalable soon.

Anyway, DR like’s the this product, and looks forward to trying it out at some point. In the meantime, check out Defense Review’s video on it, below.
