"Got this and a Noveske KFH at the same time - this is the winner, hands down. Makes my GBB pistols and AEG rifles really sound aggressive and actually does increase point blank decibel readings by about 5 - 10db on some guns (to compare, the Noveske reads the same or lower decibel readings than not using one at all, but has a more distinct and louder "sounding" pop).. Better still, it's a harsher banging sound, compared to the hollower "thwop" or soda-can popping sound the Noveske makes.

Looks good, too, and doesn't weigh a ton, so it shouldn't interfere too much with most GBB with floating/shifting barrel actions.

"Really nice and simple amplifier! I have attached it to all of my guns and it gives it a really aggressive yet sleek look. The best part it it DOES make your gun LOUDER! I let my buddy use it on his handgun for a game and he got some audible wows. 14mm negative (ccw) thread will fit almost all the guns out there. Would buy again if it ever comes back in stock
