So stupid question : I recently acquired a transferable m16 lower (colt) and now am looking for an upper as always I gat my self a HB long 20 inch and small 14inch m4 HB upper but now am looking to go with 9mm option. I see there lots of them but as I already have plenty of other 9mm smg’s and I have fired 9mm m16 smg (rental) and dislike it (its no MP5) I decided that only a 9mm upper worth my interest is if it was suppressed. So hear is my question to all you NFA fans : what suppressed upper you liked ? and if you can have only one of then what well it be if you can ignore the price ?
I personally found 2 “LRM suppressed upper” http://www.triplebreakproducts.com/
And the “Knights armament 9mm SMG suppressor” http://www.autoweapons.com/photosn/photosjul04/771knights.html the cost is about 3x then LRM but why I have no idea ?
THX 4 help
Ps yes am going to get my self the regular 556 suppressor 4rm AAC on that 14inch upper but I like to get 9mm option for my m16 gun 2
THX

Personally, I think you would be extremely happy with the LRM unit. I've shot Lee Minors (LRM) on a couple of occassions and was more than impressed with it, in both workmanship and suppression.

No need for subsonic ammo either, and I like that! :D

I have an LRM upper and it is awesome. You will not be disappointed w/ the quality and service IF you ever need it.
I think you are paying for the name w/ Knights. Also note that unless you are LE/Military, good luck w/ support from Knights.

Thx 4 info but hear is one more question first of is 9mm a good idea or perhaps the new SW40? Second of all what mag dose that 40 take and have any of you ever had any experience with it ? and finally what about advanced-armamentSpec-919 ?

I don't like the idea of integrally suppressed uppers. They all are designed to use 115gr ammo and bleed off the pressure to reduce velocity. It turns a 9mm into a .380 auto. I have a short barreled upper with Uzi threads so I can put my Uzi suppressor on it. My setup works well for me. I can get spooky quiet with 147gr ammo if I want. My 5.5” barrel is plenty short to keep moderately supersonic ammo out of a 10.5” barrel subsonic. I would contend that you shot a stock M16 9mm SMG. No wonder you didn’t like it. A 9mm M16 upper needs a heavy buffer and ramped bolt to smooth them out. My Uzi suppressor starts after just 2” of barrel.

My next pistol caliber upper will probably be in .40SW by Oly Arms. They have a mag block that fits Glock mags that I want to try out. Oly uppers use a standard bolt carrier I think, so they are already ramped. If they are not ramped it is rather simple to make them so.

I would recommend you try out somebody’s ramped 9mm upper before you run out and buy an integral upper. As mentioned the LRM uppers have a very good reputation. If I were to get one I would have him make mine with less aggressive porting so that it would not neuter the 9mm rounds. I’m not sure if that is possible, but I would pursue it still the same.

I would say that he has already been doing that. His system is not like an MP5SD that leaves the 9mm weak. I think you should talk to him about it. The rounds leave the can just under the speed of sound.
I have two 9mm upper setups. 1 I made before I got my LRM setup. Below is a picture of the one I made. That is using an UNported Gemtech 5" barrel w/ my Gemtech MK9k.
Then the bottom pic is w/o the can.
They both have their advantages and disadvantages. LRM's is nice for when you don't have want to have to reload or buy subsonic.
My 5" upper is subsonic w/ some 124 grain but for the most part I feed it my 147 grain reloads.
I think the LRM upper is a real nice smooth shooter w/ its porting.

Get an LRM upper. I have one and I use it over my .223 uppers. I have an MP5 with silencer too and shoot LRM more. Uses regular 9mm, non Walmart, not subsonic.

Paul 556 and Amphiban...that's exactly the upper I am looking for. I tired to contact a few people to make a complete on upper, 5.5" barrel that is threaded to accept a Vector screw on suppressor, but haven't had much luck. Do you mind me asking who made that for you?

Right now I have a Gem-Tech Talon 9mm integrally suppressed upper. I bought it with my M-16, used, and I have no idea of the round count. It looks perfect on the outside. However, my uzi suppressor is about 4 times quieter. My other question is...is there anyway to get this reconditioned? I don't really know too much about suppressors even though I own a couple.

Thanks.

If you get the LRM upper, Lee Minor, the LRM guy, can cut Uzi mags to fit the upper.

It is a curved Madsen mag.
Even though the ban is over Colt mags are still expensive. I think I've seen Bryan Pritchard advertise them for $75.
Topglock has them advertised for $57 but I don't think they actually have any.
And of course LRM does modify UZI mags for the Colt system for little money.

Mine is using the same barrel that is used on the Gemtech Talon but has a 3 lug adapter threaded to it.
Mine was done by Dater himself.
At that time, nobody was doing them. Now, I'd contact Mark at Tros:
Below is a pic from his ad on subguns:

Link to his ad

Regarding the Talon, Gemtech will service it. It is best to call them rather than email.

Hey Paul

That must be the cool AR you shot when we were at Marksman, Huh? Man, where did you get that barrel. I didn't realize I could use my Mossad with it. I want one of those.

Pro-Mag Colt SMG mags

As has been pointed out, Pro-Mag is making 32 rnd 9mm Colt mags in polymer ($28 retail, mfr part COL-A3).

I have it from a good source that there were problems with the first batch - lips sat a bit too high causing problems on F/A. They worked fine shooting S/A. If you see some that are unreasonably cheap, they may be early run mags.

The newer ones work fine, I have personally observed them in full auto action on a friend's gun.

How is accuracy out of the 5" barrel? When I first got my uzi I was very impressed with how accurate it was. With the 5" inch upper does giving up a few inches make a difference?

I was thinking the same thing when I got mine. Note that the Gemtech Talon is using a 5" barrel.
I asked Doc Dater at Gemtech and he was saying that it would be plenty accurate and must say that I agree.
I am VERY pleased w/ the accuracy I get out of mine.

I bought my barrel from WA Tom. It is made out of stailess steel.
The company name is Total Silence Inc. He charges $175 for a barrel like mine. The problem I have is finding hand guards that my Coastal will fit under. I want to get some that are carbine length with rails, but I haven't found any yet.

Sound Technology .38 caliber suppresser upper w/ ramped bolt by Lee Minor with a standard buffer.

Mine has 4 ports in the barrel that bleed some velocity of the bullet. Supersonic ammo will still have a pronounced crack w suppressor. With 147 gr. very quiet.

Ok, next question. Where can I find handguards that will fit a 5" upper? I don't really want the handguards to overlap the suppressor because I want to be able to fire it without the suppresor attached. Can carbine length handguards be cut?

I'm using a screw on uzi suppressor.

Why would overlapping be a problem for you?
Mine overlapps and its fine.
You a rail handguard, you can get the olympic FIRSH which is what I'm using.
For a regular free float a lot of places such as Model 1 sales sells pistol length FF handguards.
