The necessary parts and tools are listed below:
Magazine Release Button
Magazine Release Button Spring (largest spring in the parts kit)
A punch or dowel
Slide the shaft of the magazine catch through from the left side of the receiver.
Push the button down flush with the receiver. Make sure the mag catch is still captured in the receiver. If it comes out of the receiver enough so that it can turn, you must take another revolution of the threads. Make sure the mag catch will go past flush on the inside to ensure it releases the magazine. Insert an empty magazine and make sure it is captured tightly. Now, actuate the button. The magazine should release cleanly and easily.
Unparsimonious Potential Upgrade
My lack of fine motor skill notwithstanding, I am able to actuate an AR’s magazine release with my right hand. Therefore, I view choice to select Norgon’s Ambi-Catch more of an “Unparsimonious Potential Upgrade” instead of a necessity. The reason is simple: In addition to being a fan of “America’s Rifle,” I’m also a fan of the 1911. My trigger is used to pulling double-duty when the time comes to replace mags. Yep, you’ve guessed it: there’s something to be said for familiarity and pre-established muscle memory.
The next entry will cover installing the trigger guard.
