I'm in the process of installing a FA Binary trigger. My eyes aren't the best at 73 so I need to know if that is a roll pin that holds the rt. side short lever. Thanks in advance.

Yes its a roll pin. I would leave the grip on, so selector stays put, tap it out slow.

But if you are going to put it back on, you might try removing the grip, selector spring and detent, then rotating the selector to the Full auto position, and often that will be enough room of for the trigger to be removed. Much less work than messing with roll pins.

I have replaced my MPX safety, and I can tell you firsthand, yes, it is a roll pin. Turn the lower upside down, put some tape (for padding) over the "top" of the roll pin (side that would point up if you were shooting, and then use a punch from the bottom side. Be careful once itsclose to coming out, as the pin itself is long enough to make contact with a raised point in the frame and make a tiny ding in the anodizing (ask me how I know...)

As stated above, it's a small roll pin.

Not sure if it's in common with any other AR LPK roll pins, so tap it out slow and keep your receiver over a magnet or someplace where it's easy to find a small part when it inevitably drops away/out.

It took you 10 years to post, but it was a good one Wink

BTW you qualify for a CUT Big Grin




When in doubt, pinky out.
