The Advantage Arms super compact AR-15 suppressor. Measuring just 2.5 inches long, this small but powerful device significantly reduces your AR-15’s noise. When paired with an 11.5-inch AR-15 pistol, it cuts sound from over 179 dB down to just 150 dB-slightly louder than a .22lr rifle and a bit quieter than a .22lr pistol. Made from durable stainless steel, this suppressor is built to last a lifetime.
