Posi-lock click is satisfying
Reviewed on May 7, 2026Verified with Build

Geisseles posi-lock detent gives a clear tactile and audible click that you wont second guess. The ambi sides are matched in feel which not every ambi is. Throw is short, around 45 degrees. Worth the price if you do drills where safety manipulation matters.

Posi-Lock click drops in
Reviewed on April 21, 2026Verified with Build

Geissele ambi Posi-Lock safety drops into any milspec lower without modification. The posi-lock detent gives a more positive click than a standard safety. Both sides are matched in feel. Worth the cost for a serious AR build.
