My partner on the church security team put a binary trigger in his colt AR
He can switch from regular semi auto to binary mode with the safety selector.
It is a blast to shoot and in a rare instance have practical application.
One thing to watch our for is if not properly set up you can " out run the bolt" and wind up with a bolt over case jam .
His hasnt but he had it put in at a shop that builds ARs . I have seen it happen on another friends AR that just dropped it in himself .
Trying to understand how the binary trigger can cause a bolt over case jam. In my experience BOC's are typically an issue with either the mag (weak spring or lip drag) or the system being under gassed (or both!). In those instances, you can just as easily got a BOC even without a binary trigger
