Should I be concerned if my A2 flash hider is not properly indexed?

Howdy,

I picked up a Norc CQ-A (which I am really happy with), but realized that the A2 flash hider is not properly indexed.

Will this affect accuracy in any way? What are the cons of leaving it this way vs. re-installing with a new crush washer?

It looks like the Chinese LE team are not too concerned about it (see the poorly indexed CQ-A flash hider in the first pic in the following post), so should I be?

Thanks,

If all the flutes are top and side and none on the bottom it is correct, it doesn't matter where the flats on the hider are. The Chinese seem to actually index the threads and use a lock washer rather than the lazy north american way of using the crush washer!

mines not true on my norq, just how it goes,

not an issue at all, unless you need your muzzle flashes to be perfect 90 degree muzzle flashes
 
Same here to, mine is a little off to one side, effects nothing, mine is a tack driver........out shot my buddies xcr , put his $2000 plus toy to shame.........with a cocked flash hider.....he he he....
 
That's funny, everyones norcs seem to be off, yet it's a well good rifle.

Maybe it's like that on purpose. I think I've read somewhere, that sometimes flash hiders can have a slight tilt to them to also help compensate for some side movement from how the shooter holds his rifle.

Like, if a right handed shooters rifle, jumps slightly to the right while the recoil causes their body to twist.

What direction is are all your flash hiders pointing ?
 
Alright, it doesn’t really matter, but the A2 does have a slight compensation affect. Having one indexed properly and one that was off a little I thought I could fell a slight push to the side with the poorly indexed one, but it may have just been my imagination. Furthermore, it may actually be assisting your shooting, which is considering one may be pushing the rifle to one side while firing. With all that being said I would fire it and see how it feels, if you think it is pushing to one side try to adjust it.
 
As I understand it, the flats on the flash hider should be vertical, with the solid portion on the bottom to prevent the muzzle blast from kicking up dust when prone. I was just curious as to whether the current position of the flash hider could be affecting my shots (i.e. moving them off centre to the right, as the flash is being directed left). Here's a pic. As you can see, it is more than just a "bit" off.

 
Yeah, that’s more than I would have imagined… it would almost definitely be creating some push to one side. I would fix it, if for nothing else, so it doesn’t look stupid.

It wouldn’t so much as say that it is affecting your accuracy so much as it is affecting your follow up.
 
I would just spend a few dollars on a crush washer and properly index it yourself. I wouldn't think that would effect POI but it may make the rifle recoil slightly to the left.

Edit: Mirk beat me to it
 
Some Old school Service Rifle (US Army shooting team) used to index their flash hiders/brakes to counteract the rifles tendancy to wander sideways and maintain a better follow-up sight pic/follow through.
Not sure on exact amt of indexing or if it really had any benifit or not as I have never tried it myself
 
Jerry Miculek says to put the top of his brake at the 1 o'clock position for right handed shooters, I guess the same could be done for a flash hider.

Eh . . . It's a crush washer. If you are careful and have the right tools, you could get another rotation out of it.

I just this yesturday, installed an A2 on to my 16" with an old well used crush washer. If I recall, it snugged up right about where you are now, and I forced it the rest of the way till I had it lined up. I was able to feel that the torque was consistent, which told me that the washer was crushing properly, and not damaging the threads.
Trick is to vise the barrel somehow, cause if you're going to force it, you don't want to be feeding that torque into your receiver.
I clamped the Gas block in a soft jaw vise to do this.

Be advised, I do not recommend this for someone who is not intimately familiar with building AR's, and practiced at installed flash hiders.

The norinco does not use a crush washer , its a spring type lock washer ..
