3 prong flash hider timed or no?

[EMT4hire]

I recently finished putting together a parts kit build. I've got a 3 prong flash hider and a lock ring on the barrel, Just want to confirm that the 3 prongs were not timed because I will not be able to get it to line up with one of the slots pointing straight up or straight down without going over torque spec. Unfortunately I've seen a lot of photos were it appears 3 prong flash hiders actually were timed, just want to verify that is by chance and being 10-20 degrees off vertical is not unusual either.

Thank you

No, but I like having a prong at 12 o clock or near it to push any flame to the sides.

Shims for the win.

I have two, 3 prong flash hiders. I timed neither. Just torqued to spec.

If at all possible, this is what I have done as well. As said, timing is not required on a 3-prong FH.

Three-prong designs are supposed to be pretty effective at mitigating flash, has anyone compared the effectiveness at hiding flash of the early 1st and 2nd three-prong types vs the A1 FH and the A2 that followed.

I get there were practical reasons in getting away from the three-prong design in Vietnam (Breakage due to misuse, catching on vegetation) but was it any more effective at the singular task of hiding flash than the A1?

I had the 2nd pattern three-prong on a 10.3” SBR for a while and it didn’t seem very effective at mitigating flash from what I could see, but that might have had more to do with the fact that it was a 10.3” SBR. I never fired the SBR without a muzzle device at all to compare, so it’s possible the flash hider was helping more than it looked.

EDIT: Double post. I dunno what’s up with my phone but this is the second time this has happened today.

The Truth About Guns tested the three and there is not much difference: https://www.thetruthaboutguns.com/ar...hiding-test-2/

I cannot attest to the accuracy of the tests.

I timed my Surefire mainly for aesthetic reasons. I wanted the logo at 12 o’clock

Interesting, thanks.
In addition to messing with the older Retro 3-prongs, I’ve got a Surefire 3P Eliminator on an 11.5” SBR that I sometimes consider swapping for something shorter, seeing that *according to this test* the Surefire doesn’t seem to perform substantially better than an A2 might be an argument in favor of going with a more compact muzzle device.

Unfortunately I don’t have the opportunity to shoot in low light very often to test this stuff out myself.
