Most ARs are loud due to the common 16″ barrel not being long enough for a complete burn of the gunpowder, resulting in a larger fireball and concussion at the muzzle. If you think normal ARs are bad, you don’t want to be around an unsuppressed SBR with a muzzle brake.

How loud is a gunshot? Decibel levels for firearms average between 140 and 165 dB.

It really depends on the style of muzzle device used, and if you are indoors or outdoors. I would say that the AR with the birdcage is louder than an AK with the slant brake. +1 the AR is going to be louder, with a slightly higher pitch crack.

The AK-47 shoots a 7.62x39mm caliber that penetrates and damages its intended target greater than the caliber shot from an AR-15. With this larger caliber, the AK-47 has greater “stopping power” than the 5.56/. 223 round of the AR-15.

The muzzle of the AR is probably 30″ farther away from you than the muzzle of your handgun. The proximity of the concussion may make it seem louder than it really is. Also, depending on the muzzle device on your AR, it can redirect the blast to seem louder or quieter depending on your needs.

The recoil of an AR-15 is gentle to mild. You’ll feel the rifle rock against your shoulder and the muzzle rise slightly. As long as you have the stock in contact with your shoulder, it’s like a gentle thump or tap. Even shooters of small stature like women don’t have issues with the AR-15’s recoil.

223-5.56 is so loud is because of the Muzzle device. This is true to an extent. But the Most affecting factor is the fact that the . 223- 5.56 travels at over 3000 FPS in a 16 inch barrel, and a few hundred feet faster in longer barrels.

In general, a 16 inch AR-15 firing standard M193 produces a decibel level of around 167 dB give or take depending on environmental conditions. Averaging out a couple of the leading suppressors in the industry you see an average noise level of around 136 db with a suppressor attached. Which is a significant reduction.
