Shooting this will never get old.

I modified one of the printed SuperSafety trips (debo’s version) so the dwell time is basically 0. I’ve estimated it at 1200RPM based on slow-mo video. (20 rounds per second)

I also printed my bolt weight, and filled it with tungsten powder. This works surprisingly well, I cant see ANY bolt bounce in slow-mo.

Most of it is printed in PA12-CF some in PLA+ (like the brace)

I used to have so many issues with my barrel nuts softening when I used to shoot binary. This PA12-CF is taking repeated mag dumps like a champ. over 1k rounds through this exact configuration.
