ADCO just threaded my barrel and installed a FH. My question is why are the flanges on the FH not lined up with the top of the barrel, or FH?

They are just wrench flats and don't have to be in a specific position.

I thought it just looked better when they were parallel to the top of the rifle.

Rifles don't care about 'looks' - performance is the only critera.

If you want looks buy an airsoft.

Don't worry about it, that's normal and any installer would do the same.

Perfectly normal. It looks like you have an A2 there, and as long as the flash hider is timed correctly (closed end on the bottom), the position of the wrench flats does not matter.

Hmm. That is indeed odd. On all of my ARs, the wrench flats line up vertically when the FH is correctly positioned with the slits covering the nine-through-three-o'clock positions, as depicted in the following image:

Based on your image, my only conclusion is that the FH was machined incorrectly. However, as others here have mentioned. the placements of the flats are irrelevant as long as the slits are correctly positioned.

Thanks for the replies, just wanted to ask.

it probably depends on how the threads were cut. im sorry your OCD is so severe.

It is not a function of how the threads are cut but, rather a result of where the "flats" were positioned on the FH when it was fabricated.

One of my ARs has a set screw type FH on it and I would like to remove it and but a threaded one on. My question is what if who ever put the current FH on ground flat spots on the barrel to hold the set screws on the barrel can I thread over these? Also what size and thread count are the A2 type flashhiders?

my ADCO installed FH is the same way. i also have a Colt with the flats on the sides like in the other picture...

if looks dont matter, why does everyone hang all that crap off their rifles when they make those hideous M4geries?

edited to add:
looks like we both have 2 different FHs as well. look at the slots in each of the pics. the newer ADCO installed one has very small slits when compared to the second picture...
