Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

Have 3, need more!


Very happy with this Geissele ambi selector. Positive engagement with smooth rotation. I used the included detent and spring because why not? Highly recommend. Will buy more! A perfect compliment to the Geissele triggers.

Ok. A little disappointed actually

by -

I bought this with high hopes. Everything I have Geissele is first class. This fit the GGP lower very tight. It was difficult to cycle one handed, but did snap very positively. I tried it on a PSA lower, it was a tiny bit better. Finally I made an attempt on a M&P 15-22. Had to press it in forcefully (Polymer loser) Would not move hardly at all. My guess is the barrel of the selector is slighty oversized. 3 lowers, too tight on all of them. It is in my parts bin now.

NOT Configurable

by -

Just got this safety and installed in on my AR. Unlike what the description says, this is NOT configurable as to which side the long and short levers go on. They only go on one way with the long lever being in the conventional position on the left side of the receiver. I am very disappointed in this as I am a left handed shooter and need the longer safety on the right side of the receiver and the description on the website said you can configure it either way which you cannot.

We wee happy to speak to you on this matter and get it resolved for you.

When they say Posi-lock, they mean it

Extremely positive tactile lock. the selector bouncing around mags on a plate carrier is not a concern with this selector. Yet its not too stiff to be hindersome in manipulations.
