The best-looking unsafety on the market - ODIN Works Ambidextrous Modular Safety Black for AR-15

Initially, I really liked this fire control selector. The levers are a nice size and after some hand fitting, it engaged crisply. However, after a few hundred cycles, this safety refuses to prevent the hammer from falling. Lucky for me (and everyone that could have been around me), I found this out firing prone at the range. Alone and by myself, I fired a five round group and went to engage the safety... it was engaged. I selected fire, fired a round, selected safe and tested the trigger.

POW!

No bueno.

I contacted ODIN and they informed me it doesn't work with some aftermarket trigger groups. I installed it on a lower with a mil spec trigger/hammer set up.

Hammer still drops. Set it for a 90 degree throw. Hammer still drops when safe is selected.

I've managed to solve the problem by wrapping the barrel a few times with electrical tape, making it safe enough until the Talon arrives. Unfortunately, the malfunction didn't show up until after the return window closed and ODIN won't replace it.
