GENERAL SILENCER INSTRUCTIONS

Please refer to TBAC General Suppressor Instructions & Safety Information.

SR SERIES MOUNT INSTRUCTIONS

Although the ULTRA50RR-BSR uses the "Big-SR" mount, the SR Series Suppressor Instruction Manual applies to this suppressor as well. The BSR is just larger than the SR mount.

USER LEVEL ULTRA50RR-BSR INSTRUCTIONS


MOUNTING THE BSR MUZZLE BRAKE ONTO YOUR RIFLE

Only a qualified gunsmith shall install the BSR Brake onto the rifle threads. The "BRAKE MOUNTING VERIFICATION" form included with each BSR brake shall be filled out and signed by the gunsmith. The last step of mounting the BSR Brake on the barrel is measuring the runout of the ULTRA50RR-BSR when mounted on the brake, compare to the bore axis. Failure of a qualified gunsmith to install the BSR brake and fill out the form properly may void the ULTRA50RR-BSR warranty. BSR muzzle brake installation shall ONLY BE DONE by a qualified gunsmith due to the consequences if mounted incorrectly.

Additionally, in order to mount the M14x1FM brakes on the AI rifles, the face of the muzzle MUST BE faced at a 90 degree angle to the bore line. See thread print for engineering spec. AI rifles do not come from the factory with this surface faced precisely enough for suppressor alignment.


THREAD SPECIFICATIONS FOR ULTRA50RR-BSR MUZZLE DEVICE MOUNTING

INSTALLATION WARNING

The SR/BSR collar is a SECONDARY LOCK. It is NOT the primary mechanism that holds the suppressor on.

Failure to SCREW THE SUPPRESSOR FULLY ON THE BRAKE before locking the SR/BSR collar WILL CAUSE YOUR SUPPRESSOR TO BE LAUNCHED and WILL DAMAGE THE SUPPRESSOR and MAY CAUSE INJURY.

The LOCKING COLLAR is NOT what holds the suppresor on the rifle.

Here is a video demonstrating shooting the 338 ULTRA SR without the locking collar.

Damage from failing to mount the suppressor properly is not covered under warranty.

INSTALLATION

The following numbered instructions are engraved on the suppressor and must be followed to mount the suppressor properly. FAILURE TO DO SO WILL CAUSE YOUR SUPPRESSOR TO BE LAUNCHED and WILL DAMAGE THE SUPPRESSOR and MAY CAUSE INJURY.

** BEFORE CONTINUING, VERIFY THE RIFLE IS UNLOADED AND SAFE. **

STEPS

1. TURN COLLAR TO UNLOCK POINT

2. HOLDING SUPPRESSOR BODY,
SCREW SUPPRESSOR ON
(7+ TURNS TO SHOULDER)


3. TURN COLLAR TO LOCK REGION

4. CHECK GO/NOGO LINE ON BRAKE

Finally, Verify the module (if present) and RR brake are both tight.


Only the word "GO" is visible on brake (bottom of photo- on black brake). This indicates the suppressor is fully screwed on and locked.


If the word NOGO is visible (see bottom of photo- on black brake), at all, on the brake, this indicates the suppressor is NOT MOUNTED PROPERLY. DO NOT FIRE.

MOUNTING BEST PRACTICE
Once rifle is verified unloaded and safe, stand the rifle vertically between your knees.
Use both hands to screw the suppressor onto the BSR brake.
Turn it the 7+ turns until it shoulders solidly on the brake shoulder.
Once the suppressor hits the shoulder of the muzzle device, back the suppressor off slightly and, using two hands, snap the suppressor firmly onto the shoulder of the muzzle device.
Finally, turn the collar to the lock region and check the Go/NoGo Line on the Muzzle Brake

It is NOT recommended to tighten the suppressor body or collar additionally when the unit is HOT. Doing so may cause a dramatic increase in the torque required to remove the suppressor later.

INSTALLATION OF MODULE

  1. . Clean the tapered mating surfaces on the last baffle of the base suppressor and the module.
    • To clean use a Q-Tip and solvent. For the Ti surfaces use CLR, for the Aluminum use Gun Solvent
  2. Screw the locking ring onto the base can until hand tight
  3. Tap the end of the module with the palm of your hand towards the base can
  4. Tighten the locking ring with the included wrench
    • Do not overtighten -Both wrenches are not necessary for mounting the Module or Can Brake. The second wrench should only be used if a single wrench is not enough to loosen the locking nut

INSTALLATION OF RR BRAKE

  1. Verify weapon is unloaded and safe
  2. Clean the tapered mating surfaces on the last baffle of the suppressor and the RR Brake.
    • To clean use a Q-Tip dipped in CLR or gun solvent to clean any carbon on the tapered mating surfaces
    • Once clean using a second Q-Tip apply a thin layer of Permatex Ceramic Extreme Brake Lube to the tapered surfaces (as seen below)
  3. Screw the locking ring onto the suppressor until you feel it start to snug. At this point you should be able to orientate the RR Brake to the rifle in the orientation of your choosing. If not loosen the locking ring and try again
  4. Once orientated, tap the end of the RR Brake with the palm of your hand towards the suppressor
  5. Tighten the locking ring with the included wrench
    • Do not overtighten -Any time you change the orientation of the RR Brake it is suggested that you fully remove the RR Brake from the suppressor and double check that the mating surfaces are clean. It is possible that when you reorientate the RR Brake that carbon in the last chamber will come free and land in between the mating surfaces


Clean the "inside taper" before mounting module or RR brake.


Clean the "outside taper" before mounting module or RR brake.
