[edit] Minor Edit Done

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)

[edit] Pulled UltraMag info to discussion:

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.

  • Note, this is not my entry, I just pulled it from the primary section as irrelevant to the article.--Asams10 18:40, 9 April 2006 (UTC)

[edit] Major revision.

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)

[edit] Aluminum vs. Aluminium

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.

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)

Due to a complete lack of interest regarding this matter it seems that the status quo should prevail. I'll revert the article to the orginal spelling. We don't ship the guns on lorries and bum fags to smoke during breaks while we're making them. Meaning?? I could make various comments about Americans and guns, but I won't bother. Arcturus 19:51, 9 June 2006 (UTC)

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)

[edit] Picture Request

It would be good to get a picture of an ar10. The origional ar10 would be ideal.

[edit] Use by the IRA?

I seem to remember that this weapon was also widely used by the Irish Republican Army in 'the troubles' in Northern Ireland. Perhaps someone could confirm either way and, if so, should this then be added to the list of users and conflicts? Andywebby 00:19, 15 November 2006 (UTC)

That's the AR-18 actually, there's some discussion in that article. Maury
