Flash suppressors and accuracy?

Well-known member
I have a Rock River Arms A4 with a Wilson SS 16" Varmint barrel and would like to either have a flash suppressor installed or purchase another 16" standard (Elite CAR) barrel with the flash suppressor already installed.

However, I'm not going to do either one, if there's an adverse effect of a flash suppressor on accuracy.

Do flash suppressors adversely effect accuracy?

Thank you, Bowhunter57
 
Sometimes yes there is an adverse effect on accuracy when adding weight to the end of the barrel. but often the only change is the point of impact(POI). I wouldn't worry about it.

Your right about the girls, /ubbthreads/images/graemlins/smile.gif however, I will take all of the fat girls you do not want! /ubbthreads/images/graemlins/tongue.gif lol!

I had 3 post ban barrels threaded after the ban was over and using an A2 flash hider accuracy was exactly the same as before on all 3 guns. I have heard a few reports of the phantom causing a few flyers but the only one I've tried worked fine. I ordered 2 Smith enterprise Vortex flash "eliminators" today and will try the out as soon as possible.
 
Like rufus said you may see a shift in POI, but it shouldn't affect your accuracy at all. If it does I'd guess whoever you got to thread your bbl spun it between centers and didn't touch up your crown afterwards. I've done all my post ban bbls, and haven't had any accuracy issues at all. Tom you're gonna LOVE those vortex flash hiders. Best ones made IMO. First one I got made me a believer. I'm puting them on everything I can think of at this point. Haven't done the .30-30 lever guns yet, but I'm not ruling it out either....
 
I have heard many reports of flash-suppressors, when over torqued, causing accuracy problems. I have heard of armorers removing the FS and using lock-tite instead of a peel-washer or chrush-washer.

I have numerous uppers with flash-suppressors and they are all tack-drivers.

All this being said, any time you put a weight on the end of a barrel that wasn't there before, the barrel harmonics will change. It is possible to have a load that shoots good before installing the FS and poorly afterwords. Not to say that the "barrel has become inaccurate" just that the new barrel harmonics don't do well with the old load.
 
Dtech is right on.
Anything threaded onto the muzzle should never be tightened up, almost a guaranteed accuracy killer. Just get it close and locktite in position. The armourers working on service rifles have known this for at least 20 years.
I once worked on a commercial Colt upper that would change POI 6 feet at 100 yards if the muzzle brake was tightened.

Also anything on the barrel will change harmonics. This does not really degrade accuracy but will most likely require working up a new load.

I'll pass on having a flash suppressor installed, if it's going to cause accuracy problems. I may purchase another barrel with a flash suppressor already installed.

Thank you, to all that replied, I appreciate your information. /ubbthreads/images/graemlins/grinning-smiley-003.gif

Good hunting, Bowhunter57
 
Went and shot the new Vortex and it did not change my point of impact and accuracy was the same. The Smith Enterprise Vortex flash eliminators (that's what they call them) is only tightened to 10 ft# of torque with no washer of any kind, it will not come loose on it's own.

On a side note, me and my cousin both noticed it did seem to make it a little quieter, anybody else notice this?
