来自主题: GunsAndGears版 - CMMG Stripped Lower 和 RRA LPK
Well, I immediately switched to a YHM stripped lower and the RRA NM trigger
LPK installed without a single issue, after I had not been able to insert
the pins into the CMMG lower even with a mallet to tap.
Both are touting mil-spec, so one of them is NOT. It is much logical to
regard the CMMG as the culprit. Plus, there have been concerns on QC issues
arised in CMMG manufacturing in recently timeframes.
I will get a DPMS LPK to see if their holes are GTG or otherwise.

Well, got a DPMS LPK, and it installed OK with no major issue, into the CMMG
stripped lower.
Observations are the CMMG seems to be built with tighter tolerance per MIL-
spec. The trigger and hammer were barely pushed into place, and bolt catcher
roll pin was tough to drive in. Otherwise, it seems to work, and function
well.
So lessons learnt, be really careful to mix and match LPK and lowers from
diff manufacturers.
Thanks for the excellent insights and feedback here.
Muchas gracias

To all who might be in the market to build or who just like firearms info in
general,
Palmetto State Armory is offering their Classic LPK for $44.99 +s/h. Sales
Tax dependent on shipping address.
LPK - Lower Parts Kit - the components that are installed in the lower
receiver of an AR15, ie the trigger assembly, etc.
I would consider this kit equal to or better than many other standard
military triggers and components.
Price is normally $49.99.

It is RRA NM trigger LPK that I was installing.
I think the trigger and hammer pins of the NM trigger are slightly bigger
than normal pins, but it shld still fit into the mil-spec lower's holes. The
pins are designed so to eliminate possible "play" in the holes.
CMMG lower's trigger and hammer holes are tighter than the spec, I guess.
Switched to a YHM lower, installation was a breeze - everything fits, the
holes and pins, etc etc
Time to sell my CMMG lower...

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。

来自主题: GunsAndGears版 - 第一把AR15,初步构想。
buffer不一定是越重越好。Vltor A5系统中也有几个不同重量的buffer。
gas port大小,bolt/BCG重量,action spring弹性和可压缩程度(部分和extension
tube长度有关),buffer重量和子弹装药多少等很多因素决定了AR的射速(全自动时)和
可靠性。个人可以容易改动的就是buffer和action spring,光看buffer重量不能完全
说明什么问题。
.223和一些老毛子的子弹不如5.56给力,buffer太重可能会short stroke。
从后坐舒适性和控制性考虑,使用可以保证可靠抛壳装弹最重的buffer。重一点的
buffer也有助于开锁延迟使抽壳容易些。
Vltor A5使用rifle length action spring,extension tube也比普通carbine
extension tube稍长可以进一步缓和感受到的后坐并且积累更大的弹性势能保证装弹的
可靠。
如果用了.625 hand guard cap的话装Magpul mid-length hand guard应该没有问题。

1. 是的,一般这些东西(grip, trigger,spring等)通称lower parts kit (LPK),
including everything you need to finish the stripped lower.
要注意 LPK有好几种,有全都有的,有不带stock的,有不带fire control group的(
就是trigger等),一定要买全了。
组装lower要远比组装upper简单得多,可参见下边这个网页和视频
http://www.ar15.com/content/guides/assembly/lower/
http://www.youtube.com/watch?v=p6AZ1jxJGRM
注意最好备齐合适的工具,可以减少很多headache,最好要有一套punch。
upper对于新手是比较困难,所以直接买barreled complete upper就好了。

It's more likely that both the hole and pin has the same nominal dimension,
both are to the mil-spec, but are manufactured to different tolerance. So
