The BCG of my DPMS AR15 filmed at 1200 frames per second, with some really nice lighting, which is essential when trying to film a black object at 1200fps.

Quite a bit of bolt bounce, maybe a heavier buffer would hellp 😉
This is an overgassed system. Bolt velocity is too fast too soon and the case doesn't have time to rotate properly and is slamming sideways into the rear of the ejection port and then ejecting/bouncing forward to 1 to 2 o'clock. Good ejection is from about 3 to 4:30 with 3 o'clock being straight out to the right. About 3:30-4 o'clock is the most ideal. To create an ideal ejection pattern, a heavier buffer and/or spring could be used if there is a non-adjustable gas block. Of course with an adjustable gas block this could be fixed easily.
@weaponeer Thanks, yeah I usually use 600fps, but this one was shot at 1200fps then slowed down even more in the editor.
@ThrottleJunkie Thanks, probably American Eagle or PMC ammo…the cases go flying, its just hard to tell because the camera is so close to the rifle & has that narrow cropped frame
What ammo were you shooting and what extractor does your BCG have? Normally those cases fly 5 or 6 feet after they hit the deflector. Nice vid
@wavelength1970 Thanks for replying….
Yes you are right about light.
For one more time: Excellent job !!!
@Aegeanhawk Thanks! – yes full sunlight or bright overcast I can't remember…its tough to get enough artificial light for this kind of filming, plus the light sources always flicker
Amazing filming…..Thanks!
The video is with natural light ?….
