I saw a similar product on the psa website and I wanted to get one for my akv. But after watching videos on it I learned it was essentially just a barrel extension and the ports that can be seen wasn'tfunctional. So I started looking around and found this one. MI's is the one to buy and the price isn't crazy for what it is. All the ports have a directly connects to the main chamber and are functional. Although there is no baffles inside and doesn't do anything for sound it does kill the flash and direct the sound more forward. I'm happy with the purchase this thing looks great.
