I am trying to design a moderator as close as possible to the real thing, not for deadening the sound but for the cosmedic look. I can use any input that I can get. Like the outside diameter, how long are the flash slots ect. I know the length is 4.5". Here is what I have so far. It's made out of aluminum so it will be easier to make any changes to it as I try to get it as close to the real thing. Once we get the right design, they will be made out of metal.

| Before wasting any more machine time I would recommend you buying a copy of the prints. They are commercially avaialble if you seach the internet. That is where I bought mine from. Your slots are off and the wrench flats need some work. But the print I spoke of will tell all. Best of luck to you in your endeavour |
Aluminum is a metal.  . As another poster stated, aluminum would be nice for weight reasons.

I've made some out of aluminum, just to see if I could machine them. I don't plan to shoot them, though - there must be a reason why nobody makes aluminum flash hiders... It's a real PITA to make them out of mild steel, especially drilling the big holes. I used a lathe with a lever-actuated tailstock, and even that was a pain. |
Dawg180 had an aluminum one a while back and he said that it looked good but, he couldn't keep it tight. It would work loose without too much use (I don't remember if he ever said how many rounds it took for it to loosen up). Doc ETA: Fixed my spelling. Sorry Dawg, I thought it looked funny when I typed it.

I still have that one, it has a set screw in addition to threads. It woudl loosen up after only 5-6 rounds, maybe 10-12 at most, almost sent it downrange twice before I wised up and stopped shooting with it installed! Part of the problem is the aluminum is not only softer than the steel but it also has a different expansion coefficient than steel. When you thread it on, you can feel the trheads 'give' slightly each time and it screws on a little farther, and I suspect the vibration and heat of firing works it loose. I thinik even with red Loctite the would manage to work itself free. If you were trying to save weight I would just bore out the inside as much as you can prior to the threads. Unless someone is looking down the muzzle they won't be able to tell. |
