AUXILIARY MUZZLE BRAKE

The Barrett QDL Suppressor system comes with a detachable auxiliary muzzle brake. The suppressor functions with or without

this brake, depending on your preference. The auxiliary brake will alleviate some recoil, but maximum sound and ﬂash

suppression is accomplished without the auxiliary brake.

1. To install the auxiliary muzzle brake, you will need a T-25 Torx Wrench.

2. Clean the face of the suppressor and place the auxiliary muzzle brake on the front, aligning the bores.

3. Install and torque the four (4) T-25 Torx Screws to 30 in./lbs. After ﬁring the ﬁrst ten (10) rounds through the

suppressor, it is necessary to remove the suppressor from the riﬂe and re-torque the auxiliary brake attachment

screws to 30 in./lbs. to ensure proper ﬁt before further ﬁring.

4. Removal of the auxiliary brake is in reverse order.
