Hi all,
I will soon be starting my second AR build. The new rifle will be used for coyote and fox hunting and the occasional paper punching at the range. I think I read somewhere that there is an upper reciever that does not have a forward assist at all.
Question #1 - Is there such a thing and where could I get one?
Question #2 - Is it available in a flat top?
Question #3 - If there is such a thing what are the pro's and/or con's of this design when used for the purpose I intend?
Any help would be much appreciated.

DPMS makes low-pro and high-pro upper receivers : www.dpmsinc.com/10Browse.asp. (select upper receivers under "Category" there to view them)

They have no Foward Assist and no dust cover.

Yes, Les Baer carries uppers without forward assists.
I have a flattop model, and they retail for about $100, stripped.
I'm running mine without the dust cover as well as part of a fixed magazine AR pistol.
I also have 2 DPMS lo-pros and like them very much, but they are slightly heavier than the standard flattops due to the significantly thicker sidewalls.

Pros: theoretically less weight, one less part to add to a stripped upper

Cons: it isn't really a thinner profile for the the brass deflector is still there on the Les Baer model.
The upper required a lot of fitting to a non-Les Baer lower, but the result is a super-tight matchup.
No forward assist when you may need it (obviously) -- this is an issue with a finicky AR pistol recoil spring assembly often failing to fully close the bolt carrier in semi-auto fire. (I haven't tried my stronger recoil spring yet) It may or may not be an issue for you.

Having tried the standard flattop upper sans the f/a route, I would recommend against it (unless you use the lo-pro).

Cheers, Otto

(just checked www.lesbaer.com/pricnga.html $108 stripped.

I just ordered a couple Vulcan carbon-fiber uppers. They are flat top, no forward assist and no dust cover. Not to mention Damn light.
