The deadline to register Bullet-Button Style Assault Weapons has passed on JUNE 30, 2018.
If you are currently in possession of a UNREGISTERED BULLET-BUTTON STYLE ASSAULT WEAPON...



STEP 1: First, always make sure you have cleared the firearm and that you visually check to make certain that the chamber is empty and the firearm is not loaded.

STEP 2: Remove the rifle’s existing magazine release assembly making sure not to discard the spring and button parts that will be used in conjunction with the FC Hook.

STEP 3: Using the rifle’s existing mag release spring and button, install the FC Hook through the receiver while threading the arm bar of the FC Hook through the spring and into the button. (This step may vary if the rifle has a Bullet Button or RADD Lock type device installed. In such a case, you will need to slowly thread the bullet button device onto the mag catch arm and follow STEP 4 at the same time.)

STEP 4: When you have threaded the FC Hook onto the button to the point where you can no longer turn the arm, you need to press the spring-loaded detent with a flat tool or fingernail to allow the FC Hook to enter through the mag catch hole in the receiver allowing the FC Hook to lock into place.

STEP 5: The final step is to carefully install the 10 RD magazine into the receiver. First you will need to press the spring-loaded detent to allow the FC Hook to unlock and pass slightly back out in order to allow the magazine to slide into position and lock back into place with the FC Hook’s spring-loaded detent engaged properly locking the magazine catch from movement.

STEP 6: Verify that the FC Hook is working correctly to prevent the release of the magazine.  If the magazine in any way can be used to disengage the spring-loaded detent, you need to use another brand or type of magazine.

STEP 7: If you have installed your FC Hook with a RADD Lock®, or Bullet Button®, you will want to set your RADD Lock® to the open working position and put super glue into the screw hole to make the installation "permanent" so it cannot be removed while the action is closed.  With the Bullet Button®, this process is a little different.  You want to use super glue or maximum thread lock on the inside threads of the nut that screws onto the FC Hook.  If you put super glue into the BB, it will not function.  Put it on the threads only.  

NOTE: When the magazine needs to be removed for repair or replacement; Use a 1/8” thick or less mini slim flat type tool to slip between the magazine and the lower receiver in order to disengage the spring-loaded detent while pressing the magazine release button at the same time.  This action will allow temporary free movement of the FC Hook to release and replace the fixed magazine. You can trim off the edge of a credit card or gift card to make yourself a slim tool. 

WARNING: It is important to make the distinction between a rifle that can accept any magazine and a rifle that has a fixed 10RD magazine. Only a rifle with a properly installed and properly functioning FC Hook and 10RD magazine can have the distinction of being a rifle with a fixed 10RD magazine.  The rifle must have the 10rd magazine installed and fixed at all times to maintain this distinction. 

CAUTION: Once the FC Hook has been installed, NEVER FORCE the magazine into position without manually pressing the spring-loaded detent to allow the FC Hook mag catch the freedom of movement to clear space for the magazine to pass into the mag well and lock into place.  FORCING THE MAGAZINE WILL DAMAGE THE FC HOOK.   

CARE AND MAINTENANCE: We suggest that you occasionally drop a bit of light weight penetrating gun oil onto the stainless steel lock-pin to keep the shaft lubricated.


We regret to inform you that PayPal has shut down our account because
non-ffl firearms accessories violate their acceptable use terms.
Earlier in the year STRIPE Credit Card Processing also shut down on us
for the same reason. Our webstore is compatable with one last
credit card processing vendor. It is a matter of time
before our current and last optional vendor realizes we are violating their acceptable use terms by
the nature of our business. We are currently working
to rebuild this website with an alternative host so we can utilize
other credit card processing vendors. At anytime our current
credit card processing vendor can shut us down, rendering us unable to do business on this website.
If such a case happens, it will be impossible for you to purchase from
Torque Precision, until we launch our new website. This could mean
we may be down for a few weeks. We hope to launch our new site by August 1st.
