    Has anyone installed a bianary trigger in their 15-22?
    I see that a company makes one called a double tap trigger but, it is only pull and release firing. It will not do single shot so that one is out for me.
    I was wondering if either the Fostec Echo or the Franklin Armory triggerwill function in a 15-22.

    Franklin Binary: Yes

    Franklin binary trigger works on AR-15, AR-15 with CMMG .22 conversion bolt, PSA AR .22 upper, and PSA 9mm AR without any additional hardware.

    Fostech echo:
    Works on Ar-15
    Did not work on a 22 upper with a CMMG conversion unless I install a CMMG auto sear trip: https://www.cmmginc.com/product/auto-sear-trip-kit-22arc/

    ** based on available hardware that I was able to test the trigger.

    I am not sure if the M&p 15-22 has such a part (sear trip). If not the Fostech echo will not work.

    No. The M&P 15-22 doesn't have anything to push the trigger block forwards. You could use a Franklin BFS Gen 3 and it should work pretty well.

    Thank you Al. I will be installing a BFS III in my 15-22. I will update this thread when I finish it up and run some rounds through it
