I'm not sure if this is the right place for this but I couldn't find anything else about it. Here we go. On a 9mm ar can you use a standard 5.56 upper with out theforward assist? I'm notnbig on the looks of the standard 9mm upper with the shorter ejection cover. I know spikes makes a upper that's a standard 556 without the forward assist. Also anyone use a ddles dedicated 9mm lower? What's a good barrel length 5" 7.5" or 10.5" will attach a gemtech suppressor later. Ballisticly speaking best barrel length with a suppressor for 25-50yrds and 50-100yrds.
thanks. |

What is that mag block... and how can I get one???
Quoted:
I also hate the short door. The only difference would be the 556 deflector bump and the hole for the gas tube If you find a 9mm upper, no bump, forward assist, or gas hole 
And yea, my front sight is on backwards

VM Hytech mag block.
Takes un modified UZI mags. Only issue I have with it is muscle memory, I keep trying to eject the whole block and mag. Rather than using the UZI style release on the left side. I hate to say it, but I may have to voluntarily install a CA compliant bullet button to prevent it. |

Look a little farther down for the Rimfire and Pistol Caliber forum for lots more on 9mm ARs.
Any, (that means any standard upper will work on a 9mm setup (speaking specifically of the Colt-type 9s). You can even go with one with a forward assist - it won't hurt anything. The short ejection port door and plastic gas deflector are helpful in some situations, but they aren't necessary. And using a standard upper with a gas tube hole won't hurt anything either. I use a Rock River block, which stays in the mag well and requires either SMG-type magazines with a slot for the standard mag catch or Uzi mags with that slot added, so I don't worry about muscle memory messing me up. I don't know much about the best barrel length for a suppressor, but a 10.5" barrel (SBR here) kicks serious ass. |
