Talk:ArmaLite AR-10

message: Somebody repeated the commonly stated error that the AR-10's gas system was based on the Ljungman AG42B.  This is not true.  In the Sweedish system, the gas tube is used as a stationary piston and a cylinder is formed in the bolt carrier.  The AR-10 channels gas directly behind the bolt and the piston is the bolt while the cylinder is the bolt carrier.  There is no stress on the gas tube therefore unlike the Sweedish system.
I also clarified and revised some other sections.  There's a lot of misunderstanding and supposition going around about the AR-10 and future Armalite Systems.  I'll reference the following books when I get some more time:
The Great Rifle Controversy
Black Rifle, A Retrospective
I also revised some other erroneous information.  In the future, I'll add that Stoner was not the sole designer, but Sullivan had actually patented many identifying features of the AR-10.--Asams10 00:12, 29 July 2005 (UTC)
thread_title: Minor Edit Done

message: A tech note released by Armalite in January of 2006 mentions some problems associated with adapting the significantly more powerful round to the AR-10 platform:
The .300 RSUM cartridge is much wider than the 7.62mm cartridge for which the AR-10(T).  This forces the bullet tip low and in towards the centerline of the magazine.  It makes feeding far more difficult, and some loss of reliability compared to the AR-10 is to be expected.  In addition, the larger diameter cartridge cases are forced into a tight, tall stack in the magazine.  Each round loaded resists insertion more than the last.  A magazine that holds 10 7.62mm rounds will hold 5 .300 RSUM cartridges.  Higher capacity magazines are not practical. Great care must be taken when loading the magazine for the AR-10(T) Ultra.  Simply pushing the cartridges into the magazine will likely result in miss-feeds.  Once the cartridges are in the magazine, it is necessary to push up and down on the top of the stack to remove any binding that resulted in loading.  A tell tail sign that there is binding on the stack, is that the magazine will not fully engage the magazine catch if the bolt is closed or excessive force is required to insert the magazine.
In contradiction to this, a post in the Armalite forums by "Art" mentions this:
Magazines that fit any of the Armalite AR10 series (recent manufacture) are easily transformed from .308 9aka 7.62x51) to the new .300 RSAUM merely by using a dremel tool or die grinder and milling a slice out of the rounded portion of the follower, nothing more. After making the modification to the follower, 10 round mags hold 5-6 rounds of .300 RSAUM, 20 rounders hold 10-11 rounds of .300 RSAUM. Both of which fit and function perfectly. That is if you have any 10 or 20 rounders you don't mind changing to the new cartridge. Suffice to say after you mill the slice out of the follower, forget using them with the .308, because they won't.
Despite this, Armalite does not currently plan to ever sell magazines with capacity greater than 5 rounds.

thread_title:  Pulled UltraMag info to discussion: 

message: I went about revising the article.  I moved the text around alot, but most of it is the same.  I made a few corrections and additions.  The style is more wikified and there are now section headings.  If there are any fans out there with an AR-10 photo, feel free to post it.  I might have a picture of mine here somewhere.--Asams10 21:15, 10 April 2006 (UTC)
thread_title:  Major revision. 

message: I've changed the spelling in this article from Aluminum (AmE) to Aluminium (BrE). However, this change does not imply that one English national language variant is preferable to another. The article generally uses AmE in words like fibergalss. While Aluminum is the preferred spelling in North America, the International Union of Pure and Applied Chemistry states that Aluminium is preferred. In a technical article such as this, we should attempt to use proper technical language, and spellings thereof.
I made the change in good faith and for what I would consider a good reason. Such changes should not be reverted just because someone "doesn't like it". Please now leave it as it is (Aluminium) and place any objections to the edit here. If the consenus is to revert it then I'll gladly do so - give it say five days to collect some other comments.

replies: text: REVERT: You should not have made the change in the first place. Wikipedia:Style#National_varieties_of_English says that in articles of American origin, American spelling should still be used.  Whether you prefer this spelling or not, Americans still spell it this way.  The British can still make their guns out of "Aluminiuiminimium" if they prefer, but this is an article about an American gun.  We don't ship the guns on lorries and bum fags to smoke during breaks while we're making them.  We call it aluminum and the article should to.--Asams10 03:22, 5 June 2006 (UTC)

text: Meaning that, in America, we use American english.  We ship our guns on trucks and bum cigarettes during breaks.  I can make various comments about Brits and guns, but I won't bother. :-P  --Asams10 23:23, 9 June 2006 (UTC)
thread_title:  Aluminum vs. Aluminium 

message: "in-line stock, aluminum alloy receiver, and reinforced fiberglass furniture."
Maybe avoid using "furniture"? It might not be apparent to non-gunnies, what you mean.

replies: text: That's not a reasonable expectation.  The word Furniture is the proper word and the only word that applies.  It's absurd to dumb-down the article for the sake of somebody not wanting to learn the proper term.  This is not a technical term, it's the right term. --Nukes4Tots (talk) 00:17, 17 July 2008 (UTC)
thread_title:  Use of "furniture" 

message: Why Ruger's SR-762 is listed as an example of other companies making the AR-10 pattern rifles is a mystery.  The SR-762 is a unique Ruger design, it uses a piston, which is counter to one of the signature features of Stoner's original AR design. 
Much better examples of the modern AR-10 would be Aramalite and DPMS.   Armalite owns the copyrights to the original manufacturers name and logo, and was the first, aside from Knights to revive the AR-10.   DPMS was another early entry into the field.  It's rifles are highly compatible with the original AR-10 and Knights designs.  Neither companies's rifles deviate significantly from Stoners design, unlike the Ruger. 
Unless someone can come up with a compelling reason for Ruger being mentioned I intend to delete them from the article and replace the modern makers with makers who actually make AR-10 pattern rifles, not look alike guns with very different internal designs.
