Hello AR-10 was created by markthenewf
I've managed to find an Armalite dealer and they have two readily available. One is the standard AR10 flat top 20" black barrel. The second is the stainless match 20" barrel with the 2 stage NM trigger and it's $50 more for the second one. I don't get it. Why only 50 bucks more for the second one? My other question is, that stainless rail and barrel: does it interfere with sight picture when using irons? Is there any particular reason why wouldn't I want a SS barrel? I actually want a plain-jane AR with a nice trigger, but it's pretty much too good a deal to pass up for the SS one.

Mind posting what price they are offering you? To me it does not make sense.

I too am curious.... :huh: :dry:

I looked at the Home site...ArmaLite....there is a big difference in price all the way around...
The standard AR-10 A4 is $1557
The A4 with the SS barrel is 1657
The A4 with the NM trigger and SS barrel is 1757
if it a match barrel (bull barrel)and NM trigger, then it is a AR-10 T
which runs $1892...now granted these a MSRPs....so you can usually get them a bit cheaper...
Look at the lower receiver and see what it says for a designation as to the model...
It the SS is a T...then it may be used.....
I would ask some questions...use the force...USE your aggressive feelings...Make them divulge the true source.....:dry: :laugh: :laugh: :laugh: :laugh: :laugh:
Sorry...couldn't help it.....:laugh:
Seriously I would do some checking and make some inquiries...hey if you want to get sneaky about it...get the serial # and call ArmaLite and ask about them....
that is if they won't tell you...

Well I gave $1498 for my AR-10TBNF 20" SS barrel in basic black a couple of weeks ago.

The short answer is no, the rail won"t interfere with your sight picture with irons. Your rear sight will attach to the back of the upper receiver's rail. An AR-15 (5.56/.223) rear sight will work with no problems here. For the front sight, you have two options - use an AR-10 specific (it's slightly taller than a front sight for an AR-15) front sight and attach it to the pic rail on the gas block. OR attach an AR-15 type front sight at the end of the railed forend (if so equipped). Either method will place both the front and rear sight on the same plane. The biggest advantage to using an AR-15 front sight is that they are more numerous and easier to find. The slight disadvantage to mounting an AR-15 front sight to the railed forend is a slight - ~1" or so - loss of sight radius.

The biggest reason for not going with an SS barrel is longevity. The throat of an SS barrel tends to erode much quicker than a chrome-lined one. Typical barrel life for 416R stainless runs 9-12,000 rounds. As always, YMMV.

That sounds familliar and about right. Like I said, the standard black 20-incher was only $50 cheaper or something.

It's definitely not a "T". I understand that those start around $1700-$1800 and I am not willing to shell that out up front. I'd rather install a NM trigger and a floating hard guard first then do a NM barreled upper (24+inches perhaps?) if I feel better groups are 'necessary'.

I'm told that I'm a tad aggressive by nature. Definitely not passive about it. Played hockey for many years and it helps to have a rough-streak in you. I also call BS when I smell it and when someone says "I think....", I ask for proof. As an engineering type I am used to using and providing validated info.

I've dealt with this gun shoppe before, and they're fine. They beat all other prices for my last purchase there and got it shipped in from a distributor in Dallas in 2 days (for free). Perhaps I could save a few bucks somewhere else, but I think I'd have to look pretty hard. Mid/High 1400's seems like a reasonable price to me for an Armalite AR10.

Good to know. I do like to shoot irons now and again.

use an AR-10 specific (it's slightly taller than a front sight for an AR-15) front sight and attach it to the pic rail on the gas block. OR attach an AR-15 type front sight at the end of the railed forend (if so equipped).

This is also good to know. I'd rather use the front gas block and leave the hand guard clean (except for the bipod). So if I get this right, I can't use something like the Magpul MBUS? It has to be a taller sight set?

The biggest reason for not going with an SS barrel is longevity. The throat of an SS barrel tends to erode much quicker than a chrome-lined one. Typical barrel life for 416R stainless runs 9-12,000 rounds. As always, YMMV.


Then it seems that, assuming I don't want 1" groups, that the 20" black chrome-lined barrel may a better option for me. I will probably want to replace the trigger group with something like a RRA 2-stage (very nice pull & break on these) or the Armalite NM 2-stage (I've not used or felt before).

Is there that much of an advantage to the standard 20" barrel over the carbine (16"??) if I'm to be shooting 600 yards or less?

You can use a Magpul rear sight. But because the gas block sits a bit lower than the upper receiver (about 1/2" or 6mm), it requires a taller front sight to put both the front and rear on the same plane. With both sights level, it allows them to be adjusted to the shooter more easily and within the front sight's range of elevation.

At 600 yds/575m, there isn't a lot of difference. You do get more MV from a 20" barrel, which allows for longer shots if necessary. And you get a longer sight radius when shooting with irons. But you get less barrel whip from a 16" barrel, which affects bullet flight. A 16" barrel gives you a lot of flexibility - short enough to be handy close-in, long enough to reach out and touch the target when you need it.

You mentioned triggers. While the Armalite NM offering is pretty good (There's a little creep and grit in it,) take a look at Gieselle's triggers. I have their 2 stage SSA trigger on one of my 5.56 rigs and it's probably the best tactical trigger I've ever used. Coulda REALLY used it on my last deployment

Interesting stuff. I'll definitely go with a taller front sight. My handguard is for my bipod and hand only at this stage so a full rail isn't necessary right now.

From what I've read, you loose between 200-250 FPS between a 20" to a 16" barrel. That may make a difference to WWB 147gr rounds, but I think it'll have a minimum of an effect when slinging good Nosler BT, Sierra MK, or Hornady AMAX bullets down range. I think I'll be considering a carbine one at this stage because of this.

Those Giselle triggers look very nice. I wonder how a $200 trigger compares to the nice RRA 2-stage @$120. As for the Armalite NM trigger, I wonder if a good gunsmith (who knows his finishing stones) could smooth it out. That way I'd have a complete spare. I've become very accustomed to a 2-stage trigger (M1, M1A, RRA-LAR8) and others who've shot it smile afterwards.... so I eventually replace any single stage trigger should that be whats in the rifle.
