\"The<\/a>

The Gemtech G5-T 5.56mm suppressor with flash hider mount.<\/p><\/div>\n

I read a thread on a gun forum the other day. Someone with a lot of science knowledge, but no practical firearms experience, was arguing that a silencer was useless on a gun that fired a supersonic bullet. He was \u201centhusiastic\u201d with his argument that you can\u2019t do anything about the sonic boom of an object traveling faster than the speed of sound, or more 1,125 feet per second or so depending on environmental conditions. His premise was flawed, however, by his lack of understanding that the sound of a gunshot has three components. Those are the blast of the rapidly expanding gas exiting the muzzle<\/a>, the sound of the action of the gun, and the sonic boom of the bullet when firing supersonic calibers. His argument completely missed the point of all the benefits of reducing the gas expansion noise. That\u2019s what has the most impact to the shooter. He also missed the potential benefit of a suppressor masking the location of the shot in supersonic scenarios. While the sonic crack still happens, it\u2019s difficult to figure out where it came from without the associated muzzle blast. That\u2019s useful for law enforcement, military, and hunters.<\/p>\n

\"The<\/a>

The exterior finish of the G5-T is raw titanium. The standard G5 is treated with matte black Cerakote.<\/p><\/div>\n

With all that said, the bottom line is that suppressors for a supersonic round like .223 Remington are a great idea. They\u2019re loud! In fact, a 55-grain .223 Remington fired from a 16\u201d barrel will come in at about 164 decibels, depending on muzzle device configuration and such. That\u2019s way louder than the takeoff noise of a jumbo jet (150dB) and well above the threshold for permanent hearing damage. Adding a suppressor will knock that noise level down into the 130\u2019s depending on make and model.<\/p>\n

All this is a long way of saying that adding a silencer to an AR-15 is a great idea. With this in mind, I decided to test the GemTech G5-T 5.56mm suppressor<\/a>. Thanks to our friends at SilencerShop<\/a>, I was able to borrow one for a bit.<\/p>\n

\"GemTech<\/a>

GemTech includes this flash hider mount with the G5 and G5-T models.<\/p><\/div>\n

The G5 series comes in two models: the standard G5<\/a> is made from stainless steel, Inconel and titanium and the G5-T has a body constructed entirely of titanium. The blast baffle on the G5-T<\/a> is made from Inconel for durability and erosion resistance. Both suppressors have the same exterior dimensions with a length of 7-inches and diameter of 1.5-inches. The titanium model is noticeably lighter at 14.3 ounces while the steel model weighs 18.8 ounces. The other primary difference between the two is that the regular G5 is coated with matte black Cerakote, which offers a reduced heat IR signature. If you\u2019re planning on sneaking around and trying to avoid people with thermal vision optics, this model might be your huckleberry. Gemtech claims that both models offer a 32 decibel sound reduction.<\/p>\n

Mounting System<\/h2>\n

The 5.56MM Quickmount for G5 and G5-T is simple to use and offers a repeatable mounting method. This means that if you remove and re-mount the suppressor, there won\u2019t be any additional changes in point of impact.<\/p>\n

\"The<\/a>

The mounting lugs only work one way, which keeps the point of impact stable.<\/p><\/div>\n

Here\u2019s how it works. The G5-T ships with a G5 Quickmount flash hider<\/a>. The device does not have to be timed or oriented in a certain way. This makes life easier as you don\u2019t have to use any spacing washers to get it tight and oriented correctly. When you remove your existing muzzle device, be sure to remove the crush washer too if that\u2019s present. You should mount the G5 Quickmount directly to the barrel with no other washers in place. Make sure you clean the threads, and you might want to apply a couple of drops of Rocksett to keep the muzzle device in place. You\u2019ll want to torque the flash hider to the barrel with 35-45 foot-pounds of force.<\/p>\n

The Quickmount has two lugs of different size that mate with two holes in the suppressor body. Simply press the suppressor onto the mount (it will only go on one way) and push hard enough to overcome the spring inside the suppressor body. Now rotate 90 degrees and make sure the spring pulls the suppressor back away from the muzzle. To remove, pull the suppressor towards the rifle, rotate 90 degrees in the opposite direction, and it will slide right off. It\u2019s a simple system, and I had no trouble getting the suppressor on and off during range outings after it got hot and dirty.<\/p>\n

GemTech makes a slew of Quickmount devices with different thread patterns. Right now, you can order the following:<\/p>\n
