I have a DPMS "post ban" rifle and considering on installing a DPMS A1 flash hider. While doing a little research, a local gunsmith said that adding a flash hider would change the harmonics of the barrel and could affect the accuracy of the rifle. Is this true

not on a DPMS rifle. The FS dinks with harmonics at sub MOA numbers. so if your groups are 3/4-1MOA you won't have problems. now your gun smith can easily mess up the barrel if he installs the FH wrong. he can turn a 1MOA gun into a 3-4 MOA gun. MOA is minute of angle. 1 minute is about 1" at 100 yds. good luck. find a good smith! |

I tend to believe that idea, that a flash hider isn't exactly the hot set up if you're interested in accuracy. And if you think about it, when was the last time you saw a flash hider on a dedicated target or varmint rifle? On the other hand, you have to wonder, "How much does it affect accuracy?" I have a post ban Bushy w/20" chrome lined barrel. This rifle is plenty accurate enough for me and it serves as my test bed for testing all my handloads. I'm actually glad that its muzzle isn't "garbaged up" with stuff it doesn't really need. On the other hand, my new Super Light 16" carbine is going to get a flash hider (pretty much just for the Hell of it and because the Liberals don't want me to have one).

Yes. Find a good smith that knows the formula for cut back. Also watch that they do not crush the barrel while threading the muzzle. And for gods sakes do not damage the crown (sticking steel in the muzzle, ie die guides)! |
