S**********s 发帖数: 4534 | 5 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

and accessories designed specifically for these firearms. Legion’s

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。 |

S**********s 发帖数: 4534 | 25 “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

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.

我也说下我的经验
琴颈的relief不一定要0.5mm,可以根据需要调整
如果要调整nut可以用nut file
一是不需要把nut敲下来,二是可以分别调整每一条弦的高度
缺点是nut file太贵,一套至少50
我也用过welding tip cleaner来锉,好处是便宜,只要3块
缺点是操作不方便,比较费时,毕竟不是专用锉刀
但是锉得不多的话还比较划算 |
