Anybody? And do all buttstocks and lower receivers fit on any lower receiver?

if you want just a plain flat top upper, this is probably the way to go $87 in stock

just about all buttstocks designed for ARs will fit on any AR lower receiver. the caveats are you need to make sure you buy the right buffer tube (aka receiver extension) which could be commercial or military type, rifle or carbine length. some versions of buttstocks are also made for AR10 vs AR15

What's nice about buying just an upper is that they can ship it directly to your house...

March 25, 2010, 03:11 PM Click "barrel assemblies" This is best deal on the net I have seen so far.

March 25, 2010, 06:27 PM
Yes any lower will fit any lower.

And any upper will fit any lower. BUT Colt used smaller pins in their commercial AR15s for awhile. So while one of those Colt uppers will go on another lower and another upper will go on those Colt lowers you may need offset pins to make it work.

For the Del-Ton assemblies, is that all I need besides the lower and the buttstock and pistol grip?

What about this? What do you think?

What about this? What do you think?
I would buy a stripped lower and an assembled upper (upper, barrel, handguard, gas block, etc) since spacing would have been checked. You can then buy a lower parts kit for your stripped lower and a stock (either collapable or not).

A lower is the only item that needs to go through a FFL (the portion with the serial number). I have a RRA assembled upper mated to a Spikes lower.


March 27, 2010, 04:46 PM is this a complete assembled upper?

Why does everybody read this, but don't reply?

March 27, 2010, 09:44 PM
get a Bushmaster Upper they are mid ranged priced and they are much better then Rock Rivers. RRA has better lowers but i rather have Bushmaster lower and upper - u cant beat its accuracy and reliability for its price!

Except for some Colt lowers all AR15 Upper/Lowers are interchangeable.

I suggest you buy a Bravo Company upper:
or a Daniel Defense upper:

Either is worth the price and there really are differences between the various makers.

The two I mentioned are considered "tier 1" and will not only perform well but will also hold a decent resale value.

Personally, I like the mid length gas system uppers (unless you want rifle length). The midlengths are much easier on parts wear and perform very well.

Because when a reader opens the thread and sees the absence of any specifics in your post, they don't want to waste a bunch of time repying to such a vague question.


"Considering price"?

You should at least include what kind of upper you want... M4 copy, carbine, Midlength, A1, A2, A3, NM, barrel length, barrel material, handguard configuration, etc. Intended use?

What price point? $500? $1,000?

March 28, 2010, 02:28 AM
I will be using this gun for coyotes, rabbits, squirrels, plinking, and for pretty much anything else I can. As far as specifics on what kind of upper I want I am not sure and that is why I have this post. I am wanting something as close to the $500 range as I can get.

I'll poke in here, from an AR newbie...

Is it 'better' to get an upper with or without the M4 ramps? Can one with them be used for anything but .223/5.56?

March 28, 2010, 07:19 AM
has a good deal on a stag 16" m4 profile upper with BCG, Charging handle, and BUIS.

March 28, 2010, 09:25 AM
M4 ramps are better. They aren't key for 5.56, but are rally nice to have. They are important to help feed larger rounds like 6.8spc and especially 6.5 Grendel. due to the rounds larger diameter, the bullets tip sits lower, and hits the ramps lower.

So If you choose to rebarrel to one of those you must have m4 ramps.

I would check out this page:

$500 doens't go too far, but there are a few pretty good uppers at about that price.

Personally in a 16" I would look for light weight barrel profile, chrome, and mid-length gas system, or a 1:8 stainless barrel if a heavier profile was desired.

In a 20" I would consider stainless 1:8 twist.

I want accuracy at a few hundred yards for varmints, I want reliability, something that will last for a long time, and I want to spend as little as I can.

March 29, 2010, 10:04 PM what about this place?

March 29, 2010, 10:10 PM
Found this one...looks pretty good...?

March 29, 2010, 10:14 PM
I'm kinda aimin towards something with a bull barrel or at least stainless. What about this?

March 29, 2010, 10:27 PM
If you're looking for a straight up varminter, check these out. Come with everything you need in an upper, sans sights, ready to be slapped onto a lower, and all under $600

Do some research and develop some specific questions. Provide us with your parameters/wants at the beginning of the thread. Otherwise a lot of folks will be throwing around opinions that have nothing to do with answering your questions. You will find that many of the posters on this site take a tremendous amount of their time to help point you in the right direction. Do your part and make sure they aren't wasting your time or theirs. I'm not trying to be critical, it just seems like the thread was started prematurely.

March 29, 2010, 11:41 PM
I think the uppers I posted above are going to be your best bet for a varmint rifle.

It's like a car accident. You can't help but to look.

March 30, 2010, 01:00 AM if I were to get this, could I shoot 5.56 military surplus ammo? I've been told that you can shoot .223 from a 5.56 and 5.56 from a this true?

March 30, 2010, 01:04 AM
You'd have to call DPMS to find out if it's 5.56 or .223. You CAN shoot .223 from a 5.56 rifle, but not the other way around due to cartridge pressure. So I'd call them to be sure what it's chambered for.

March 30, 2010, 01:06 AM
Is it that big of a loss if I can't shoot 5.56 rounds?

March 30, 2010, 01:11 AM
Not if you're using it for hunting. All of the good hunting rounds are .223. 5.56 is more military rounds. Whether you're hunting, target shooting, or plinking, you can find what you need in .223, so there's no big loss at all.

March 30, 2010, 01:13 AM
Forgot to add, .223 is generally more accurate than 5.56 as well.

March 30, 2010, 08:51 AM
What makes you think .223 is a more accurate round.
