I have a Scout Squad with SA's proprietary muzzle brake.  Works great.  It's loud.  Flashes like a roman candle.  Does all it's designed to do.

Given my intended use for this gun, I'd like to put a flash suppressor on it.  Does the Vortex offer anything more than the standard M1A flash suppressor?  Only advantage I see is that it's slightly shorter in length...which isn't too important from my point of view.

Secondly is there a flash suppressor for the M1A that would prevent/eliminate a dust signature when firing prone?

I think the USGI suppressor is better at eliminating a dust signature when firing prone in daylight, but the DC Vortex is better at flash suppression in low light/dark conditions - it also eliminates the castle nut.

A Gemtech HVT works as a good FS that eliminates dust signature.

Does the M1A flash suppressor have closed bottom port?

YES

10-4, I think I'll just replace my SA brake with the USGI flash suppressor then.  I like the general pupose role of it's design.  Furthermore I weigh eliminating a dust signature over absolute flash suppression.

Thanks guys
