AR18 突擊步槍

I'm a target shooter at heart and any gun that can't

shoot reasonably accurately (for a military rifle,

2-3 MOA or 2-3" group at 100yd) I'd call junk.

探討步槍命中精度

暫且排除射手因素　純以槍械機械設計觀點

以AR18而言　必須找出其影響原因

我們暫不將其可以抑震制退防火之槍口裝置導入　以免掩蓋住真因

分階段下改良對策　（一次只針對一項機件）

　最後綜合各項改良　作系統組合印證

　首要　

活塞活塞環

瓦斯鋼管瓦斯通道

瓦斯導管　活塞環

氣筒　瓦斯排氣孔

復進導桿動作連桿氣筒座夾環

連桿彈簧

Ar18 was derived from AR16 (Stoner designed in 7.62NATO,

mostly stampings for easier manufacturing and low cost)

after Stoner had left Armalite.

The purpose for AR18 is to be licensed to 3rd world

countries that did not have the necessary industrial

know how to produce the (much desired) AR15. AR18

has never been sold in large quantities nor has been

licensed to any military. The manufacturing right was

passed around and eventually to Howa in Japan and later

to Phillipine and never goes anywhere since the

late 70's (I think).

The only thing worth noteing is the fact that the

British firm "Sterling Manufacturing" copied most of

the design and transformed it into SAR80 used in

Sigapore.

The design philosophy of the AR18 is actually very close

to that of the AK's - cheap, reliable, and easy to

manufacture. Because of that, tolerance is loose and

accuracy is ... let's say "not so great".

: : 　邁向突擊步槍時代　晚了8年而已（六五式步槍研發成功）

: You are right in that M14 is not a good assault rifle.

: It was never meant to be. M14 was designed to compete

: AR18 is junk.

哇　我的字典中 junk 意為舊而無用的廢物

（曾有外籍槍械專家憑論 T65 為 COPYCAT）

: Maybe there are merits in its design,

相較M16

　AR18確實是只需中技術層次工業國家即能製造

就如上文所提

　需　”將AR18的設計理念能再精進研伸”

　主要修改是∼　復進系統設計與材質

　　　　　　　　機匣設計與材質

　　　　　　　　折疊槍托設計

聯勤民國62年仿製AR18突擊步槍　亦有修改

　防火帽　刺刀座　固定槍托　…….

　並非完全仿製

AR18並非如此拙劣

　從後期一些突擊步槍來印證 AR18

　您會發當年設計者的前瞻

但若以實用可靠性來憑論AR18

　確實是不盡理想

M16的威名　已難讓其他國家接受 AR18

: : 五七式步槍讓我們錯失　以AR18作為基本架構所延伸設計的國造突擊步槍

: : 　否則T86就不是今日的模樣了　

: : 　相對民國75年國軍換代更新SS109彈藥　所使用的新式突擊步槍

: : 　絕不是今日近似M16A2的T65K2

: : 　將可能採BULL-PUP設計　

: : 平心而論

: : 聯勤失去了幾個國造突擊步槍的重要轉型契機∼

: : T57步槍　　　　　＜－　未能說NO　：（

: : 　（M14）　　　　　　　^^^^^^^^^^

: How can anyone refuse at the time? M14 is big, accurate

: and powerful. And most of all, it was free. ROC military

: got hundreds of thousand of M14 *free* through lend－lease

: type of military aid program for year before they acquired

: the entire production line for a good price in 1967.

: Remember that after the retreat to Taiwan, the ROC military

: was still armed with bolt action rifles dated as far back

: as late 19 century (such as some of the Hang-Yang mausers)

: and M1 and M14 was such a big leap forward.

: What more can anyone ask?

以當年中美關係　爭取到M16並非不可能

　美國士兵的體型　都難已掌控M14

　更何況是平均中等身材

M14到臺灣成為T57

　改進為僅具半自動射擊模式　是為正確對策　

: BTW, the assault weapon concept was still very new at

: in the 60's and even the US military (Dept. of War) rejected

: the concept by barring Springfield Armory to participate in

: the small caliber rifle development program. M16 was

: a design that had to be forced down the military's

: throat by a civilian committee...:

武器系統的設計　是隨戰術需求與科技水準而改進提升

但非每一項武器需要到實戰考驗後才知落伍

有時這將付出許多代價

不過　M14輕量改良設計的Mini-14與AC556　卻令人激賞

Don't know what is AC556; but Mini14 (designed and manufactured

by Ruger) has nothing to do with M14. Totally different

design.

或許是我分析之差異吧

　因是設計的觀點而言

M1－＞M14－＞Mini-14－＞AC556

AC556系列相當多　（下次再列出）

上圖只是其一近似構型

主要差別為∼折疊式槍托　射擊模式　手槍式握把

各型之間還有∼槍管長度　折疊式槍托　準星座　防火帽　上護木　材質…..等不同

不過　AC556應該在美國民用槍械市場上　已無法販售

　除非是舊槍

Two Types of Mini-14 Ejectors

I recently received a series of e-mail letters in which writers were debating about how violent the ejection of empty brass was from a Mini-14. One side contended the brass was about as dangerous as the bullets being fired while the other maintained the brass was propelled only a few feat and landed in a neat pile about a yard from the shooter.

As noted by another in the group, actually both sides were correct. As one owner of a Mini-14 noted, the Ranch models do throw the brass some distance while the standard Mini-14 ejects brass forward and to the right about 4 feet.

Why is this?

The standard Mini-14 and AC556 series have a spring-loaded ejector on their bolt (like most military rifles including the M16) while the Ranch series uses a bumper ejector more like the .45 Auto pistol. The spring-loaded ejector is pretty gentle when it kicks the empty out. On the other hand, the "bumper ejector" works like a hammer to kick the empty out with a lot of velocity. Both work well, but you don't want to stand to the side of a Ranch Rifle's ejection point. (Or the ejection port of any gun - but especially those with a bumper ejector.)

將Mini-14非常輕巧的改裝BULL-PUP設計

以前亦曾有國內槍械專家發表建議　將M14改為BULL-PUP設計

　不過7.62mm之彈藥　還是不適用於BULL-PUP設計的槍械

如果是在美國合法擁有M1A　定想依其設計理念（槍口裝置需再重新設計）

　修改為M14　 BULL-PUP　（具全自動射擊）

　一定非常”酷”　　　^_^

: :以M16A1對M16system如此詳細分析,本人覺得十分難得,相信花了

: :不少時間在這問題上,不知提出此問題的人,對此答覆是否滿意?

: :尤其提到M231這是設計給裝甲運兵車兩側射擊孔用的特殊槍支,可

: :見M16A1對M16系列有深入的研究,不是吹牛的.

喜愛M16　所以特別關注　^_^

M16A1是另一個筆名∼槍神的代稱

事實上我已極少使用此頗具爭議性的筆名
