Dangerous trigger releases hammer on reset - OpticsPlanet Exclusive Timney Triggers Calvin Elite AR Triggers, 1.5lb Pull, Small Pin

Purchased this trigger and took it to the range. First magazine was great and suddenly I had a few double fires; at first I assumed with the 1.5lb I may have been "bump" firing so I tested by slowly letting the hammer reset and after 4 or 5 attempts sure enough randomly it would fire on reset. After returning home and removing / reinstalling the trigger I performed repeated function tests and had the same results.

Contacted Timney via their website form and no response.

Having this occur randomly is absolutely terrifying.. This is my first and last Timney trigger.
