GEMTECH’s TREK 5.56mm suppressor for carbines offers OSHA-safe hearing protection – for the shooter and those around -- that is ready no matter what surprises the job may bring. Connecting directly to the threads of an AR15 and other similar rifles makes the TREK low-cost and short (adds only 4.7 inches to the system) solution to hearing damage claims and an increase in officer safety. The suppressor is inexpensive enough to be used patrol-wide yet durable enough for SWAT.
