把柄那一边较粗的部分钻孔, 自己做一个小金属柱,把金属柱子塞进孔里面, 用JB
WELD 粘, 应该可行
可以先粘一下, 试试

我也觉得可以试一下J-B Weld。不过应该可以直接用,不用像须刀说的那么专业。不行
了再专业点或买零件也不迟。

谢谢各位的建议,零件是根本买不到的。与厂家联系过两次,就根本没有配件卖。

JB WELD看起来比一般的SUPER GLUE更强大,还真没用过,试试先。
再次感谢!

来自主题: GunsAndGears版 - FNAR 还是FN FAL?
I've done my homework in searching for a .308 battle rifles and I would
strongly recommend an AR 308.
An AR can be lighter, cheaper, and more accurate than G3/FAL/M14
Parts, accessories and upgrades are readily available, and competition
lowers their price and brings up their quality.
Accurizing an M14 is viable for a hefty price, I can tell you that from
experience, but in the end you will get a heavy lump of a rifle.
Accurizing an FAL? I've only heard it has been done by some gunsmithing guru

You might not like the knoxx stock, because if you like consistent cheek
weld, it not only doesn't offer that, it also slams back in your face.
maybe you can put a soft cheek rest over it.
and swapping any barrel on mossbergs should take the same amount of time,
which is about 30 seconds:
unscrew the retention cap
take barrel off,
put new barrel on,
rack the slide,
screw on the cap again.

当然, AR上最容易出问题的几个地方之一。
在美军里M16也是USGI铝弹匣最爱出问题。 刚发的还好, 旧的用时间长了就不爱好好
供蛋了。
另外....不妨把前准星座去掉,换个折叠的, 这样就不需要那个riser了, 不然瞄准
基线这么高你枪托还没有cheek riser, 如何cheek weld?
镜子可以换个短的或者再往前装点, 这样就可以NTCH。

来自主题: GunsAndGears版 - legion usa 和毛子的legion有没有关系?
有些疑问,希望诸位解惑。
一: legion usa的website上说:
Legion USA, Inc. is a an importer of AK-based Saiga rifles and shotguns
produced at the Russian Izhmash factory, as well as authentic Russian parts
and accessories designed specifically for these firearms. Legion’s
headquarters are located in Izhevsk, Russia. The American division of our
company, however, is situated in southern Florida in the city of Hallandale
Beach.

我自己没用过任何降低recoil的东西, 站着打霰弹从来不觉得后座大, 倒是夏天的时
候坐着打slug肩膀会疼, 这时候我用背包或者厚衣服垫一下就好。 那个limbsaver
recoil pad不错, 可以考虑shoulder pad这玩意, 基本上就是一个比较厚比较硬的东
西, 抵消一些后座, 并把后座均匀的分布开。
我强烈推荐一个cheek pad, 我用ITC cheekrest, 黑色wet suit的, 里面塞的是一
层层的泡沫塑料, 可以自己调厚度。 本来我买它是为了垫高cheek weld适应瞄具的高
度, 但后来发现装了这个贴腮要舒服太多了。

The FN PS90 is a very interesting carbine with many wonderful attributes.
Unfortunately, the factory ring sight leaves a lot to be desired.
Picatinney rails are available for several sources and while they allow the
use on any desired optic they are very often too tall for the user to get a
proper cheek weld. We currently offer 2 different optics mounts for the

来自主题: GunsAndGears版 - 推荐个flash hider给自己装AR的朋友~~~
NJ 不许用 Flash Hider,YHM Phantom 5M1 或 5M2 都是 Muzzle Brake,NJ 合法。
5M1 带尖刺,样子比较“邪恶”,5M2 是平头的,“清纯无辜”一点。两个都不错,网
上一般卖 $25 到 $30 之间。螺纹都是 1/2 x 28 标准的,但NJ 不许螺纹枪口,所以
Muzzle Brake 必须 pin & weld ,光拧上不行。

1. Are you shooting slugs? Should have gone with a compact scope with a

experience few cheap red dots will.

Jpoint and docter reflex are very good open reflex sights.
But if you already have a red dot, try and google vent rib rail adapter. IMO
they usually raise the sight height too much in comparison, and the major
cause of shotgun cheek slap is improper cheek weld.

网上有人这么说:
If they are plastic mags you can epoxy the blocks in yourself easy.
If they are Metal mags use JB Weld steel embedded epoxy.
Someone can correct me if I am wrong but converting high cap mags to legal
mags in CA must be permanent.
Pinning the block in would be to easy to remove and would not meet the

不管是大洞小洞, 觇孔式瞄具需要眼睛贴近后瞄。 眼睛贴的越近, 后瞄就越虚, 挡

我常提到的nose to charging handle就是一个很好的cheek weld reference point.
再近就是那些打service rifle match的姿势了, 不适合实战。

来自主题: GunsAndGears版 - 我特警打枪都不用贴腮?
“无托枪贴个屁腮”
说这话的人我应该罚你20个俯卧撑。 如果你是来喷人的, 那慢走不送; 如果你想学
知识, 不妨看仔细了。
我得从哪说起呢...从贴腮说起吧, 无论是铁瞄, 光瞄还是反射瞄具都有视差(
parallax), 从射手的角度, 减少视差最好的办法就是一个固定的贴腮点, 因为你眼
睛离瞄具的高低远近都会让弹着点有相对的变化, 如果没有一个固定的贴腮点, 那枪
就打不准; 另外一方面是速度, 每次举枪, 脸都贴在同一个位置能节省很多瞄准时
间。
从瞄具基线到枪托贴腮位置的高度叫drop at comb, 太低了没法瞄准, 太高了没法贴
腮, 影响瞄准的速度和精度。
再说说无托枪, 无托(bullpup)不过是把action挪到了扳机后面以缩短全长; 无托枪
通常是直枪托, 所以瞄具所需要的高度和AR15这种有托的直枪托的枪是一样的----固
定提把的M16, 95, Famas等枪的铁瞄高度是正好的, 允许射手正常贴腮射击。
而95, FAMAS, M16在固定提把上加了瞄具以后就不能正常贴腮了, 而是所谓的"chin

A 12 gauge shotgun should weight around 8-8.5 lbs. If it's too light the
felt recoil would be hard to handle.
Stay clear of PGO (pistol-grip only), those are hard to shoot; or any of the
recoil absorbing stocks. They are either spring loaded or hydraulic, they
may reduce some felt recoil, but too much rearward movement of the gun means
improper cheek weld or get smacked in the face by the receiver.
