Just a safety suggestion; you may want to clear and empty the weapon before putting your hands in front of the muzzle of a hot and chambered gun...

I put the chevron muzzle brake on my ak. Flatter shooting, faster follow up shots. Don't notice the flash so much at an outdoor range. Great video 👍

The second one you're asking the name of is called a Chevron compensator. Like the gas station. Chevron is that triangular design.

I got the exact same gun.....i love it!

Shots look a lot more controlled and staying on target with the second one. Also charging handle condom 😝

More flash on the 2nd one
