FC Hook

$39.99 $36.00

THE 'FC' Logo has gone DARK.  It will no longer be bare metal, We're now coating the FC Hook with Black Oxide in the final step of production for a beautiful semi-gloss finish. 
Awarded U.S. Patent No.: 10,132,584 B2


The FC-Hook is a 100% U.S.A. made Patented Magazine Lock Device. Essentially it is a Enhanced Magazine Catch device that contains a spring-loaded locking-pin that is built into the Magazine Catch with laser-guided surgical precision.  It replaces the AR rifle’s standard mil-spec Magazine Catch.  It works with any standard mil-spec Magazine Release as well as the *RADD Lock®, and the *California Bullet Button®. 

This devise turns your rifle into a "fixed magazine" rifle that is compliant according to 2017 California Penal Code and recognized by the DOJ as a rifle that is not required to be registered as an "Assault Weapon".

Just like a standard Magazine Catch, The FC Hook can only be removed or disengaged when the takedown pin is pulled and the rifle upper receiver has been pivoted away from the lower receiver.  

Removal and reinstallation of the FC Hook takes less than a minute.  

Simply use the Slim Tool provided, to disengage the locking pin while the action is open to remove and replace the Magazine.  

You can also reload your magazine through the ejection port with mag loading products like the BEAR FLAG DEFENSE BF-10®.

Retail Product Package Contains:

    • FC Hook

    • Slim Tool

    • Installation Instructions

Mil-Spec Magazine Catch Buttons, Magazine Catch Springs, and Replacement Slim Tools can be purchased separately. 

(*)(When using with a RADDLock® or Bullet Button®: We recommend that you use an epoxy or strong adhesive thread lock to install with The RADDLock® or Bullet Button® so they cannot be removed while the rifle is assembled.  Otherwise, we recommend switching your RADDLock® or Bullet Button®  out to be replaced with a standard mil-spec mag catch button and spring.)

Here's a short little installation video



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.


Due to the changing landscape of legislation and regulation in California, All sales are final.
We will replace any defective FC Hook or Torque Precision made products within 90 days
from the date of purchase as long as you have proof of purchase from us or any authorized Dealer.
We do not have a warranty or implied warranty, however we do strive to provide excellent customer service,
and we will consider issues on a case by case basis.
Please contact us if you have any problems with your order or the products you have purchased.
