    Here's a prototype 6310 (has been redesigned for better flash suppression) vs a longer factory AR10 flash suppressor on a 13.5" barrel.



    We again see more flash in the flash suppressor body, and towards the end of the slots there was blooming.

    Open ended and longer prongs do a better job than close ended and short flash suppressors.

    I take it that the camera sees more than the eye concerning the pictures you posted. The flash would seem much smaller to our eyes in the field than these pictures show.

    The flash happens so fast, the normal 30fps camera can miss the flash entirely sometimes, really need to use a high speed camera to capture more frames. We take side way pics, even though it's not from the shooter's vantage point, to better capture the flash, since from the shooter's position, the flash from various devices all looks pretty similar, unless it's really noticeable. If it appears a little brighter to the naked eye, it's much brighter on camera.

    In the 6310 tests, the flash signature looked identical to the shooter and bystanders. It's only after we captured still frames from the footage did we realize they're not the same. An M16/AR15 A2 has TDP dimensions and tolerances, not so much for the 308 "A2", it's an elongated version of the military A2. 6310 is a tad shorter than the Armalte Ar10 A2, the intermediate and secondary flash characteristics are quite different and that can't solely be traced to the shorter length. The original 6310's exit hole is larger and its cone shape quite different, which we believe caused the shape and size of flash to vary.
