B&T’s IMPULS-OLS 9mm Suppressors take much of their design from the renowned IMPULS-IIA Suppressors, and offer the perfect balance of noise reduction and minimal weight/size. The IMPULS-OLS measures in at roughly the same length as its predecessor, and weights almost 4 ounces lighter. Rigorous testing during the development of the IMPULS-OLS proved the suppressors were both reliable and effective. In addition, the IMPULS-OLS suppressors are adjustable for point of impact.
