AR10T, what's the difference?

[yoyogreg]

Does anyone know the difference from an AR10T and a regular AR10.
I have an Aero Precision AR10 lower reciever and I have seen AR10T complete barrels with upper recievers for sale and I want to know if they will fit my standard lower and if it is a good idea or not. I guess overall I want to know the difference.
Thanks,
Greg

Ummmm...I would start off by erasing this post and looking to see what lowers are legal/not legal. I'm fairly certain that AR10 lowers are listed...

I think when the OP says he has "an Armalite style AR10 lower reciever" he probably means that he has "an Armalite AR10 style lower reciever". Transposing the words "AR10" and "style" in the sentence can make it sound like he has a listed AR10 lower rather than an AR10 compatible off list lower like a Noveske or Aero Precision.

Armalite AR10T upper receivers will fit on Armalite AR10 compatible lower receivers, like the Noveske N6 and the Aero Precision.

Not an Armalite Lower

Now that It's clear that I don't have an illegal lower Does anyone have an answer?

u should call aero, ask them what upper design will fit??

If your lower is an Armalite-pattern lower, then you need to use armalite-pattern uppers.

As to the differences between a 'standard' AR10 upper and the AR10T upper appears to be a free float tube and a stainless barrel without a flash-hider. Is that what you wanted to know?

Don't spread FUD, Aero AR-10 lowers are perfectly legal, just as Noveske AR-10 lowers, because they are not listed.

note that Sypder's post was from before the OP edited the OP and and stated that he had an Aero lower.

There are three tiers of uppers in Armalite's inventory:
1) Armalite Eagle uppers are chrome-moly, not chrome-lined (it appears that Armalite is sort of dropping the Eagle name brand). Least expensive.
2) Armalite upper are chrome-lined double lapped chrome moly barrels. They are service oriented, mid-range in price.
3) AR-10T are accuracy oriented, most expensive, and as mentioned, free-floated stainless steel barrel. The barrel manufacturer may very from Lothar Walther, Obermeyer, etc. depending on the batch.

Your Aero lower will fit any of these just fine.

I did not notice, thank you for bringing it to my attention. Post deleted with apologies to Spyder.

Thanks Everyone,
my question was answered. I think that I am now leaning towards the AR10T upper due to higher quality and accuracy.

FWIW, I have the mid-range Armalite AR-10 on a Noveske N6 lower. It is a chrome lined double lapped heavy 20" barrel. Today I was reaffirming zero on my scope. Strung the first three rounds right and high about 3". Fourth shot was 3/4" right. Clicked 3 times left at 1/4" per click and put one dead center. Then I picked a virgin sight-in bullseye and shot a 5-round 3/4" group. The stainless steel triple lapped barrel is likely more accurate and I've heard will likely wear our sooner too. I'm very happy with mine.

Your Aero Precision AR10 lower will fit Armalite AR10-compatible uppers. (It will not fit DPMS/Fulton uppers.)

Be aware there are numerous reports (incl Armalite) that the AR10-T is tuned expressly for 168gr Fed Gold Medal match ammo, and may not cycle other common loads - including milsurp like Aussie, Radway Green, Portuguese milsurp 147gr ammo - as well as bulk white-box Winchester FMJ 147gr ammo.

If you are looking for more general purpose usage and want the ability to use other than Fed 168gr GMM ammo, you should avoid the AR10-T - while a fine upper, and tremendously accurate, it will barf with other loads.

I have a regular AR10A2 upper and it shoots very, very, well with match ammo and it's not even freefloated. And it feeds milsurp just fine.

Most folks do not necessarily have the shooting ability to detect the quality of, nor ammo budget to feed, an AR10-T a consistent batch of match ammo.
