是说那个牌子的Muzzle Brake,还是泛指。 |

p********f 发帖数: 5148 | 4 我家俩猫肯让我刷牙,可不知为何特恨grooming,刷毛,剪指甲都是一场战争。前两天
买了这个muzzle
今天初试,确实容易多了。猫咪两眼一抹黑,啥都看不见,乖乖就范。只是心里还是很
怨恨的。陪陪还好,剪的时候稍事挣扎,剪完照样在身边粘着。cocoa从头到尾气鼓鼓
的在肚子里咆哮,完事后muzzle一摘,不敢把妈妈怎么样,只能拿陪陪出气,上去劈头
盖脸一顿巴掌,陪陪被打得一愣一愣的。好可怜。 |
|
l******8 发帖数: 9475 | 5 可以试试。 只是不推荐带muzzle, 因为有很多时候是没有muzzle可带的。
让LG带, 他有劲。 有情况时他可以一下把狗拉开。 关键是人要时刻眼观六路耳听
八方。 |
|
p*******y 发帖数: 4518 | 6 啥叫没有muzzle可戴啊?我们周末出去到人多的地儿就戴上muzzle不行么?

mix of WWII weapons after the war's end.

14.5和16拿在手上比差别也不大
14.5和18拿在手上比差别很大
考虑16的可以考虑18
18可以可靠的上rifle length gas system(RLFS),17也可以,但17基本全是定制的,
拿18或20的管子锯短些,17现货一般没得买。18上的gas system比较多了些,有mid
length, intermediate length和rifle length,从后坐舒适性还有零件磨损性来讲,
rifle length最好,但市场上不是很多见,BCM(Bravo Company Mfg)的18 upper都是
rifle length,质量非常高,可以看看。
18的初速比16高一些,存速也大,可以比较有效对付较远目标,特别是配合重些弹头使
用(如77gr OTM的Mk 262子弹)。Navy的Mk12 SPR就是这个用途。近战,看家,一两百码
打猎,SHTF等不一定需要18,其实16的AR对付三四百码之外的目标镜子配好了也可以.
18的份量要重些,可以考虑不用四面全长导轨,而是像Mk12上碳素纤维护木加3/6/9短

新浪军事

暗战一般指的是有别于正式军事斗争的情报战。对于委内瑞拉近期国内的动荡局势,美
国一直扬言将武力干涉委内瑞拉作为一种选择,使得该国如临大敌。
然而,最近委内瑞拉警方缴获了一批从美国发出的武器弹药,其中步枪、弹药、瞄
准镜、电台等应有尽有。看来美国是选择了武力扶持委内瑞拉国内反对派或者是反叛军
人这一“暗战”策略。

委内瑞拉内政部周二表示,这些美国制造的武器是在委内瑞拉巴伦西亚市阿图罗·米切
莱纳国际机场的堆场发现的,据称来自于从美国佛罗里达州迈阿密飞来的一架空中客车
N881YV航班中携带的包裹。
这批武器包括19支步枪、118个弹匣、4套携行具、3套高倍狙击瞄准镜、90台电台
和6部手机。目前委内瑞拉内政部门已经展开调查,以确定该批货物的预期接收人。

D******r 发帖数: 491 | 39 The conversion job is so so, but it's a sweet shooter.
But the barrel is not threaded(no muzzle brake), and no bayonet lug.
I tried one with a ak74 type muzzle brake installed, the recoil is reduced
at least 50%, muzzle jump almost non exist, but that sucker is really loud. |
|
L*******r 发帖数: 8961 | 40 I agree that the longer the barrel the higher the muzzle velocity. It again
says that the energy is the product of the air pressure and the bullet
travel distance.
E = F x L
E is the energy, F is the air pressure and L is the length of the barrel.
L is fixed for a particular gun. Unless F is different when shooting bullets
of differnt mass, the muzzle energy is the same regardless of the mass of
the bullet. With the same muzzle energy, the speed of the lighter bullet is
higher.
E = (M x V x V)/2 |

b*****e 发帖数: 5133 | 43 加州合不合法需要自己调查了,我就只对配置说两句:
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
stock有点小改进,主要是locking更好,如果不在乎,可以用更便宜的MOE。另外既然
考虑SOPMOD这种比较贵的,就可以考虑一下Vltor A5,和它有名的E-MOD stock有配套
出售,也有分开只卖tube, spring和buffer的。A5比其它的carbine stock稍微长些,
使用rifle action spring,对整枪的可靠性有帮助,开锁抛壳减少short stroke,闭
锁减少bolt bounce,对付over gasing也有效。A5极有可能成为下一改版M16的标准
buffer和stock系统。如果用镜子打远目标可能大比例高的话而可以牺牲一点份量和整
枪灵活性,可以考虑Magpul PRS,调整到合适的length of pull和comb对稳定枪支打远
距离很有帮助。

b*****e 发帖数: 5133 | 48 应该是这个Brakeout 51T compensator,后边的孔算muzzle brake,前面三个叉算
flash hider
这个页面是AAC他们的7.62消音器产品,有转向使用90T快接头的趋势,51T在5.56消音
器里AAC好像还用的较多。
http://www.advanced-armament.com/762mm-Rifle_c_19.html
先看中意哪个消音器,然后装个支持这个消音器接口的flash hider或muzzle brake就
成了。也有不使用快接口而就直接使用螺纹的,muzzle thread pitch要相匹配。 |
|
b*****e 发帖数: 5133 | 49 Muzzle brake和flash hider大不一样,工作原理和重量基本没有关系,当然效果好的
muzzle brake需要一定体积,小不了也轻不了。
好的muzzle brake枪口火焰可以很大。
好的flash hider对抑制后座和枪口上跳能力很有限。
两个功能都有的膛口装置大都两种效果都一般,但很多情况下足够了。 |

要我不套上一个金属筒就可以吗?那这个真的不麻烦,
其实只要在靶场测一下枪口的noise spectrm,然后根据这个设计一个Resonator,然后
去掉外面的筒,就说是Muzzle Brake。用CAD设计一个然后用一个小型CNC加工一个
Muzzle Brake很容易啊。真正要用的时候加一层吸音背板,然后用金属筒一套就是一个
