Different charging ear design? - Griffin Armament Suppressor Normalized Ambi Configurable Handle

Waiting to finish my build so I can’t speak to durability and design, HOWEver, I CAN speak to the fact that the charging handle received is different than what my buddy’s snach charging handle looks like. His finish on the charging ears look more durable and have an L sort of shape on the rear of the ears vs my square or flat back ears. Not sure if griffin changed manufacturers or finish, but his just feels more durable and sturdy tbh. I’ll have to update this review later but I’ve emailed griffins customer service to explain why the shift in finish and charging ear design. Honestly, at the cost of this I’d probably have done a bcm or raptor knowing the finish would look exactly the same. Can’t speak to its effects on suppression yet.
