具体结构的区别在哪里？
刚看了一下KAK的介绍，说是铝的。

To avoid potential patent infringement, the KAK cans do NOT have a muzzle chamber large enough to create sufficient back pressure, which is crucial in Noveske's KX design. Although they share the same look and almost exactly the same external dimensions, the interior chamber dimension of KAK cans is smaller than Noveske's. In addition, the KAK can has a one-piece body design, whereas the Noveske Flaming Pig has a two-piece body; the latter design allows you to clean the inside of the muzzle chamber, which will get carbon deposit over extended use. One last difference between the two brands lies in the material used, just as you have mentioned. I actually prefer the aluminum KAK slim can on my 10.5" DI AR pistol, as it is much much lighter than the fat and chunky Noveske KX3. However, the $35 KAK can might not work so well on the 7.5" midget ARs due to the inability to generate back pressure, according to the KAK official response on AR15 forum.

Sorry to hear about the issue...I really wished Adams Arms could live up to my expectation, but I guess my growing confidence in this brand is somewhat misplaced.

Midget AR pistols do seem to have a much higher risk in having gas related issues. Well, case proven.

这帮人直接抄保加利亚四件不就行了，绝对没有专利问题。

当年我买的spikes的AR手枪，叫做concussion，就是直接抄KX3。
这个东西里面的锥容易被枪口焰烧蚀，外壳用铝是没问题的。

Don't worry, most people will not have shot enough ammo through the can to even scratch the funnel, me among one of them. No one has reported any issues with the chamber erosion on forums yet, we'll wait and see whether aluminum is just as good as steel in regular range use. My take on this product is that if you have $35 to spare, give it a try on your AR pistols, it's fun!

You should not mail them your lower or to anyone who do NOT have the legal paperwork, such as a legal FFL license. I am not a legal expert, so I'd always err on the safe side. Maybe someone else here can weigh in on this issue? I am just not sure...

寄回原厂的枪拿到了。试射4个弹夹，有556和223，无一卡壳。厂商说是receiver out of specs.他们给我换了个新的。Adams Arms 客服还算不错。整个过程比较smooth...... 我对这把PSA下身，Adams arms的ar pistol还是很满意。相当的准。
