The question is often asked, “what is the best handgun for concealed carry?
” There are many valid answers to this question and they usually begin with
, “well, it depends on a number of factors.” However, in my humble opinion
, there is one universally valid answer, and that is, “it is the gun that
you have on you when you need it.” With that said, the purpose of this

The 13 percent decline in the Dollar Index since June has led some OPEC
members to call for oil to rise to $100 a barrel.
The U.S. currency's weakness means the "real price" of oil is about $20 less
than current levels, Venezuelan Energy and Oil Minister Rafael Ramirez said
after yesterday's meeting of the Organization of Petroleum Exporting
Countries in Vienna. The group, which accounts for 40 percent of global
crude output, left targets unchanged and called for greater adherence to

New York-based Murti first wrote of a ``super spike'' in March 2005, when he

barrel是卡在upper receiver上的。bolt gun不同,barrel是旋在action上的。
“Video truing a Remington 700”这个系列里说了要让Rem700打到1/2MOA的话,
需要true action (its thread), bolt face,让他们都在轴线上。
AR barrel 的结构是
barrel旋在barrel extension上,barrel extension提供了locking lug。
只要barrel extension, bolt都在barrel的轴线上,就和upper receiver没有关系了。
GA Precision的GAP-10可以打到3/4,factory guarantee。Les Baer和Larue都有
类似的精度保证。我在想,如果我自己要安装同样的精度的AR话,是不是只要

Re: Cylindrical bore vs rifled barrel for shotguns
If the barrel is true cylinder it's probably a riot gun, cut off, or a
barrel meant for slugs or buckshot. These are, or should be, pretty
inexpensive and rightly so. There just isn't much good application for
hunting with these barrels. I'm guessing you will find an improved cylinder,

我喜欢9mm,用开花弹力量也够了。
Glock G26 Sub-Compact: Haggle Price $500-$530
Polymer frame. Weight: 19.8 oz., Barrel: 3.50", Magazine: 10 rounds
The Glock 26 was specially developed for concealed carry. The G26 is a good
backup companion pistol for those that carry the full size 9mm Glock. There
are tons of accessories and holster choices for the Glock 26. The most
popular police backup pistol of all time.

很早之前看到的,nick和我朋友小猪,老陈,都买了这个BCM SS410,以后要多蹭。
枪老板的Noveske SPR,以后也要多蹭!
"For my money, in the 5.56 AR arena (tactical side, not match side) I've
been extremely satisfied with BCM SS410 barrels and will continue to go that
route in the future. I think they got the profile right as far as weight
goes. Not too heavy, but heavy enough so that POI doesn't walk even when the
barrel is heated up. They are also hand lapped, and do well with a wide
range of ammunition. 1/2 to 3/4 MOA performance with 77GR SM... 阅读全帖

恭喜入新枪
加州禁止short-barreled shotgun / rifle
short-barreled shotgun: barrel less than 18" or overall length less than 26".
short-barreled rifle: barrel length less than 16" or an overall length less
than 26".
所以 18" barrel 是你在加州可以买到的最短SHOTGUN BARREL长度了
千万不要自己锯短

来自主题: Military版 - OPEC 达成减产协定 zz
The Organization of the Petroleum Exporting Countries on Wednesday committed
its fractious members to their first oil production limits in eight years.
Now comes the hard part.
OPEC has agreed to cut production by about 1.2 million barrels per day, or
about 4.5 percent of current production, to 32.5 million barrels per day.
Top oil exporter Saudi Arabia faces the unenviable tasks of policing cartel
members and keeping crude prices within a range that will relieve pressure
on oil-producing countr... 阅读全帖

If you want to know what is hot in the gun industry you have to get to the
annual Shooting, Hunting, and Outdoors Trade (SHOT) Show held every January.
Manufacturers, retailers and even we members of the press all descend on
Las Vegas to see what products will dominate the market in the coming year.
Earlier this month, the 2011 SHOT Show gave us a pretty clear view of what
cool new guns to expect this year. Here is a sample of just a few of the
great new guns co... 阅读全帖

Futures jumped as much as 2.2 percent after the UN voted to establish a no-
fly zone over Libya and demanded a cease-fire with rebels. Oil clim... 阅读全帖
