Don't think your second question is a side issue at all. 9mm Luger ammo was designed for a 5" barrel. Wait til some heavyweights offer up their wisdom, but my guess is no supression would flash the same as a hider. I doubt there's anything left by the time you get to the end of that 16"

Quoted:
Does anyone know why RRA 9mm uppers come with A1 flash suppressors instead of A2s? Is there a reason - A1 works better w/9mm? Side issue: Do 16" 9mm barrels with regular load (Blazer Brass, WWB, etc.) 9mm produce enough flash to worry about suppressing it? Are they as bad as 16" .223s? Damn good questions. I will wait for dark and report back. |

I have a RRA 9mm upper that came with the A1 FH. My ST-22 upper also came with the A1 FH. Actually I dont have a scientific explanation, but I exchanged both A1s for A2s and havent noticed any change in accuracy nor recoil.

Because that is what COLT put on them in the first place.

Wouldn't that be a reason to do something different?

As a pseudo-submachinegun you are unlikely to shoot a 9mm from the prone positon, thus you are unlikely to need an A2 flash hider with the closed bottom hole.
My guess, it may be a little quicker to assemble (i.e. cheaper) since you don't have to time the flash hider. I doubt you need to worry about flash. Look at the end of an MP-5 barrel. It's a lot shorter than 16" and there isn't even a flash hider on them. Same for the Uzi. |
