The Firepig sound amplifier now comes with its own tracer making it a two-in-one product. Wesley Airsoft shows you more... "I come to show a review of these muzzle device: Flashhider #Firepig #tracer #Spitfire- it is a shooting simulator for airsoft, it releases a light close on the tip of the suppressor, sensational effect Flashhider Firepig Sound amplifier- it makes the AEG sound drier making it more beautiful and natural, maybe the video cannot be observed 100% but personally it makes a lot of difference. Seal Parts - this suppressor is 10 cm, it is beautiful, apparently. If you know other suppressors comment on their name I want to test them AEG used g & g CM16 MOD0 - black Important to use fluorescent orange or 'bright' red at the end of the barrel."
