Complete upper receiver：PSA#46027，$700
http://palmettostatearmory.com/i ... -iron-sights-1.html
Followed this post: "[枪·火] look at this upper"
http://qiangyou.org/bbs/forum.php?mod=viewthread&tid=11346&extra=
这个upper虽然被认为贵了些，但是基本上包含了我想要的主要features:
- CHF
- 410SS over 416SS or 4140/4150
- .223 Wylde over .223 or 5.56
- 1:8 twist rate over 1:7 or 1:9
- rifle-gas over mid/carbine/pistol gas system
- keymod 15" over shorter rail or other type rail
- NiB BCG
- muzzle brake over flash hider。这点对我很重要，因为MA不允许用flash hider，这下不用费心费钱另外买了。看照片这个brake不会差。到手之后查到用的是“Lancer Nitrous Compensator 1/2-28 - Stainless Steel LNC-223-SS”， （http://palmettostatearmory.com/i ... eel-lnc-223-ss.html），PSA#33994， 售价$70
- 另一个购买动力是，这个upper和前一个upper可以一起送到gunsmith那里pin+weld，省了一趟跑

Lower Build Kit: PSA#37346, $150

到手之后，觉得那个STR stock太bulky，不喜欢。MA又要求把stock pin死。正好周末有个gunshow，去买了图中的固定托，$50. 找机会把这个STR stock卖了。

固定托装上去非常稳当，纹丝不晃，长度大概是神所托2~3click的位置（0最短）。虽然1的位置最理想，但差那么一点点倒也无所谓。

Lower: Joe Bob billet, $110, following the post of: "喊一嗓子，快去抢又便宜又漂亮的lower，Free Shipping"

装了一个forged lower，组装这个就更容易了.

front/Rear folding sight/set: PSA#38182， $70

Pin+Weld muzzle device: $40, local gunsmith

Lower Build Kit: PSA#37712, $230, for premium full-auto profile BCG, and MOE grip and stock

Muzzle device: Rainier Arms XTC Muzzle Compensator, $48 when on sale

Pin+Weld muzzle device: $40, local gunsmith
The upper originally came with A2 flash hider, which is illegal in MA, have to either remove the thread or permanently attach (blind pin + weld) other muzzle device.

lower组装比想象中的容易，两个pin基本上是用钳子（Tongue and Groove Pliers）加进去的，记住钳子上要垫东西保护lower的表面，剩最后一点点不好夹的部分，用冲子+锤子轻轻敲进去就行了。
