    I just got it and took it out at night and fired 5 rounds of Wolf and there is only a slight amount sparks coming out the barrel. I could see it when I fired but the video I took showed no spark at all. It also did not have the famous 'ting' flash hiders often have. At least we didn't hear it. I recommend.

    Product was effective. Hides muzzle blast significantly. Only complaint was some mild sparking. Decent price for quality.

    Shipping was lightening fast. The quality if the flash hider is perfect. Well finished and made. Can’t wait to fire my AK with it since I’ve installed it. The YouTube videos impressed me

    Just received my FH-4AK flash hider. Desogn and execution are top notch. Speaking of notches, having multiple front sight detent notches made snugging up the FH a snap. Don't hesitate to get one. FH matches the nitrided finish on my PSA AK perfectly! Great Job, Fellows!!
