Must have received a defective one - Presma Ambidextrous Charging Handle 223/5.56

I really wanted to like this handle. Good price for features. Lightweight, and strong enough. The only issue was that it would not stay latched on a heavier recoiling .300 Blackout upper. I noticed that the handle was popping me in the nose every 2 or 3 shots; having come unlatched. I would push it in, and it seemed secure, but it would do it again. The range officer noticed, and wanted me to put away the gun as malfunctioning. I swapped to another handle, and no recurrence. Will save the handle for emergencies, I guess.
