AK vs AR
Here is my take on AK (Kalashnikov) style rifles vs AR-15 style rifles. For
simplicity's sake, I will consider AKs in 7.62x39 and ARs in 5.56x45 NATO. I
own both, and I like both, and I have experience running both in carbine
classes, for whatever that's worth. AKs and ARs have different design
decisions. In general, the design decisions that give one its strength, also

Compact 9mm Pistols for Concealed Carry
We didn't do a "best list" because your personal requirements for a
concealed carry pistol will not always be the same as ours.
The rules for the 9mm CCW list: Weigh 30 ounces or less, barrel 4.1 inches
or shorter, and cost less than $600 from a dealer. Most confrontations will
be at 7 yards or less, so any choice you make from the below list should be
good for concealed carry. Some of these compa... 阅读全帖

AR15 gas system goes by the distance of the gas port to the chamber. Typical
systems include pistol, carbine, mid length, and rifle gas.
16" barrel can utilize both carbine gas and mid length gas system
The closer the gas port is to the chamber, the higher the force that is
applied to the bolt.
By lengthening the gas system with mid length, the bolt and receiver
lifespan is somewhat increased and the felt recoil is slightly dampened.
That is the merit of mid length over carbine gas system.

For people interested in Japanese firearms of WWII, the name Mukden Arsenal

In real shtf or in a situation where ur scope or cco is either damage,
broken, or sometime come loose out of the scoket, ur are screw/fuck.
If u keep the iron sight, if the scope fail, u can alway put that iron sight

12月27日去靶场测试96FS,旁边一老美在打他的Taurus PT 145。和他聊了一会儿后,提
出借用他的枪打20发体验一下。
口径:.45ACP
长度:6.1", 3.25" Barrel
高度:5.1"
厚度:1.2"
弹夹携弹量:10+1
frame: polymer
slide: steel
night sight: available
这把枪不是特别合适我的手。握枪的时候小指总是放在弹夹的seat上。Grip手感不佳,
可能设计时候对手小的人没有特别照顾。
枪很轻,感觉比G19还轻一些。.45ACP的后坐力贼大,打完一发后居然把手震的枪口向
上60度左右。第一发准确度不错,但是每次把枪口调回射击位置时间长;三次double
tap第一发在9环内,第二发都在6环线上;估计需要一段时间的磨练才能有效使用。
枪的front sight和rear sight都是fixed,但是今天偶所有20发都偏左上,那个老美打
得pattern也是偏左,不知道是sight alignment还是俺们俩人握这把枪的姿势不对。
枪上有night sight,但是大白天的根本看不出来效果。

SOPMOD对有些人来说宽了些,而且价格比较辣手,性价比不高。Magpul CTR比MOE

来自主题: GunsAndGears版 - Daniel defense M4咋样?
研究了一下,V3的sight是fixed。如果打算装flip up front and rear sight,应该是
V5更好些,可惜12"的rail长了一点。flip up sights跟fixed sights比有何缺点?

来自主题: GunsAndGears版 - SIGP226的射击感受!
P226是用的combat sighting,不是6oclock sighting. 目标要被白点盖住。从6oclock
sighting 换到combat sighting就会偏低。

是的,sight pusher都是上百的,如果是universal sight pusher,可以用在不同枪上
还值这点钱。
如果只是更换一次,还是找个有经验的gunsmith,邮寄也可以,套筒法律定义上不算枪
,随便寄。最好的是gunsmith会给你test fire,这要求你把套筒,枪管和复进簧一起
寄出去,对方有套筒座装上就可test fire。还有就是能拆能装的sights就一定有松脱
的可能,所以一定要找一个有经验的gunsmith。最不爽的就是装完新的sights却发现打
偏了或过了一阵自己掉下来。

来自主题: GunsAndGears版 - SubCompact对射手要求挺高啊。。。
很少看到过HK,good, trigger三个词在一个帖子里出现,呵呵。试过HK所谓的match
trigger(USP elite,expert),不要说1911,跟sig的da/sa扳机比都有差距。
HK的塑料枪比别家的贵一倍,搞出的产品很让人体会到HK hates you的精神。就拿USP
来说,USP的bore axis比1911高,1911又比XD高0.2寸的样子(XD比glock高0.1寸,
M&P在两者之间),大伙都明白高bore axis后座枪口跳的厉害吧。
为了减轻后座又弄了个双弹簧,双弹簧把后座能搞出很奇怪的pattern来
(有人说是figure8,有人说是inconsistent muzzle flip and sight
return of the USP),速射或比赛大忌。做的也不是多耐用,别家坏的地方它还不是这样坏,看看以前为HK打比赛的运动员现在改HK为生的枪匠怎么说的

来自主题: GunsAndGears版 - 反省一下,NRA Pistol Exam考题
昨天把NRA Pistol Instructor Exam的考试部分提交了,回复是50道题错了一个,而且
是不应该错的问题,贴出来反省一下:
The basic rule for sight adjustment is:
a. move the rear sight in the opposite direction that you want hits on the
target to move.
b. move the front sight in the same direction that you want hits on the
target to move.
c. move the rear sight in the same direction that you want hits on the
target to move.
d. none of the above.

来自主题: GunsAndGears版 - 新采购的M&P45的扳机
M&P新枪扳机不爽,主要是trigger bar, firing pin block, sear, striker leg等都
不算精加工,打磨光滑靠自己多打。
普通M&P,扳机感觉(主要是最后击发)改进最大的还是那个Apex hard sear,也非常容
易换,只需要一个1/8" roll pin punch,同样在Brownells上可以一同买了:
http://www.brownells.com/.aspx/pid=5551/sku=230-100-004/Product
当然还需要榔头啦,呵呵,最好还有几个软木快,破布等垫着就成了。
sear block pin敲出来,sear block拿出一半让sear pin露出来。sear pin是松的,一
顶就出来了,换上hard sear再原样装回就成了。当心sear下面的弹簧弹出来,顺便看
看是不是大号的sear plunge/sear spring。
firing pin block边角笔直而不圆滑,扳机杆推动时比较涩,但一旦顶上去后也就好了
,不影响最后一段击发,你不在乎就不一定要换那个圆滑边角的Ultimate Strike... 阅读全帖

来自主题: GunsAndGears版 - 今天的USPSA比赛体会
我曾经抱怨过我的sig combat sight picture.甚至差点换掉它。今天突然发现其实自
己已经习惯它了。仔细想想主要是因为终于找到了速度和精度的合理平衡。过去是心理
习惯性地单纯追求精度。眼睛总是在sight和target之间不停扫描好几次才开一枪。现
在基本上精力集中在sight上,USPSA的目标其实都不太远,基本上不太用费劲看目标。
这时候combat sight picture就显出优势了。这个我觉得主要是心理关。
今天还试射了一起比赛的S&W MP和CZ75 shadow
两个都不错,上手很舒服。body index很自然。CZ75shadow比较重,射击感觉和我的
sig没太多区别。
特别说说S&W MP,真的真的很棒。虽然这个是trigger job之后的,但除了trigger其他
感觉也特别好。尤其是指向和复位。我特别加快了速度射击,仍然非常准。真的很喜欢

来自主题: GunsAndGears版 - 新枪处女射- 什么问题
Q: My SigSauer pistol is not accurate. Why? What should I do?
A: All SigSauer production duty/combat pistols are set up to use a "combat"
sight picture. This is where the front sight completely covers the bulls eye
of the target. Using a six o'clock ("pumpkin on a post") or center mass ("
half'n'half") sight picture will result in low impact. SigSauer, Inc sights
in all non-sporting and non-target pistols for 2.5 inch groupings @ 15 yards
