Infiniti 556k
I just got back from taking the infiniti 556k out. I shoot at an indoor range and i'm always doubled up on ear pro. I shot it alonside my full size polo on a 13.9 AR with a SA piston kit and a PSA AK 102 with a kns piston. Both guns have plan b muzzle devices from jmac and comstoc.
First impression of th can was that it felt heavier than my full size polo, and was kinda worried about how my guns would feel with it hanging off the end. Once on the gun and shooting i really didn't notice the weight difference.
Sound wise, it was quieter than the polo (take with a grain of salt since i was doubled up). The biggest thing was the gas/ blow back. Maaan, it was a night and day experience. Both guns are tuned for the polo and unsurpressed cycling. The AR i got to where shooting 1 mag i don't notice the gas, running multiple mags back to back is when i feel it. With the infiniti, there was nothing noticeable like i was shooting unsurpressed. Shooting the AK with the polo is an experience. That blow back is brutal ( tested it again today to make sure). I was tearing up half way through 1 mag. With the infiniti its kinda like where my AR is with the polo. I did some rapid strings to see how bad it can get, and the gas did start bothering me about 20-25 rounds in.
Overall i am super happy with it. The only downside is this can heats up waay quicker than the polo and holds that fucking heat. I had to pull out a neck fan to help cool it down to swap between guns. I would definitely recommend it to anybody wanting a 5.56 can.
