Geissele Maritime Bolt Catch
I just installed one of these. It looks and feels real nice. As noted, it gets in the way of a trigger pin installation.
I took off a few millimeters with a drill and a dremel attachment. The metal was very hard and it took a very long time. It was very precise work and hard to hold it together. I had to take an edge off at the point where the trigger pin install and the catch collided.
Despite the extra effort, I think this is the best bolt catch available.
