What do you guys think, does a flash hider affect accuracy or not? My buddy says his AR didn't come around accuracy wise untill he took off the flash hider. Have there been any test done on this subject or not?
Thanks~

An awful lot of highpower service rifle shooters would tell you it is not a problem.

Vortex flashiders actually help accuracy. Don't think a properly made flashider would hurt anything.

Some people think that crush washers put stress on the barrel and effect accuracy. I don't know either way, but I guess its plausible. I used peel washers on my precision build because once I spent all that other money on it, the extra .50 didn't seem like expensive insurance to wring out every bit of accuracy.

I don't know what level of accuracy you need, but I have a couple RRA guns with flash hiders that will shoot sub 3/4 MOA, 5 shots with match ammo.

I had one on my M&P15 and I don't think it did anything. I think it's all marketing hype. |

How is the noise level with the vortex???

If the barrel didn't have one yet had a perfect crown, that would be the best scenario, no ?

Flash suppressors, or muzzle threads at least do two things from a mechanical point of view.
First, by turning down and threading the end of the barrel, there are enormous forces being put on it. It is possible that reducing the diameter of the barrel can cause the bore to expand ever so slightly and threading does not help matters. Second, is the torque from the muzzle device. Many highpower shooters will time the suppressor with a peel washer and then put some blue Loctite on the threads to keep it in place, thus putting a very small amount of torque on the terminal end of the barrel. Torquing up a crush washer, again, puts some pretty serious stress on the barrel. All of this is from a pure accuracy standpoint. Most ARs are not accurate enough to notice it, but if you stack up enough variables, something will bite you in the ass sooner or later. |

The more you post the more I value your opinion, (not like I didn't from the start, cause you always made sense to me), so.... anyway, what do you run ? |

I run a brake on my carbine, held on with Loctite, and a Phantom on my SPR-ish rifle secured the same way. They torque to position hand tight. Both of them are 1/2x28. Neither are what I consider precision rigs, though. I run muzzle devices on those because I'm more concerned with running the crown into something than anything else given the way they're used. Any new barrels I make will have 5/8x24 threads, if they have threads. If I build another Service Rifle, I'll probably just crown it and go.

As a highpower shooter, I hand-tighten the A2 FH as does the AMU. I dont torque it.
