Does anyone make a light weight upper of the follow spec, which I'm thinking would be a great ultralight build:

-14.5" bbl, pinned to 16" with one of those lightly stretched A2 flash hiders.
-light weight / skinny bbl
-Standard front sight with bayo lug, with a flat top upper  (would consider a railed no-sight block though I suppose for the weight savings..)
-No forward assist (As Stoner intended) - but with the shell deflector  (only time I use that thing is when I probably shouldn't.)
-and while at it, chrome 1/8 or 1/9 bbl with M4 ramps (this ain't an 80 gr launcher).
-Carbine gas system.

Anyone make something close to that?

You might have to build this one.

Daniel Defense lightweight barrel and a Ranier Arms or Spike flattop upper without the forward assist housing.

Pretty much this.



It's unlikely you'll find that specific set of features on a pre-built barreled upper. Almost all of the pre-built flat tops come with a forward assist. Only exception I can think of is possibly the DPMS Sportical or the S&W M&P Sport. But those won't have the barrel length or profile you want.

Thanks,  yea, I think I'm hosed on this one.  Was hoping to just buy something pre-assembled.  I did find someone that makes exactly the upper I'm looking for:

$140 seems a bit high for a stripped upper though...

i agree but they make them in smaller numbers using a modified spec so its not surprising thats it costs more. check out aero precision

In my recent 3 gun build I used an AP slick side upper $100ish, 6.6oz and Rainier MedCon barrel $260ish, 30oz.  

Why carbine gas?

The AP upper is solid and the Rainier barrel is very accurate.

Your barrel specs is the hard part. Most 1/9's will be commercial type barrel and most 14.5" carbine gas is going to be M4 profile.

so you're dead set against 1/7? it shoots 55 grain fine and presents some better options...

That sounds like a neat build - very light!  Do you miss the brass deflector though?

To answer your question, it seems like the designers intended it to be ~4" from the gas port to the muzzle.  Carbine gas system was designed for 14.5" carbine length bbl.  Middy gas system for 16" bbl.  So if doing a 14.5" build, wanted the carbine gas system.  Plus it's kind of neat being able to mount a bayonet if you really want to.

Thanks I had a different interpretation of "slick side".

I still prefer midlength. I have 2 carbines, 1 was my first AR the other is a 10.5" SBR. Anything 14.5" or 16" and over, I want a mid gas. Over 16" I want rifle gas. My mid is much smoother shooting, without a doubt.

Sorry for the bad description. I like the upper. I don't miss forward assist, but I would want it for HD or hunting.
