Be sure to check EVERYWHERE for all the components of your lower parts kits

So about 3 weeks ago I was building a lower (EA stripped lower, DD lpk) and became evident that my kit was missing the bolt catch plunger. I was pissed and began cussin DD and midway for all they were worth. Ordered another one for like .99 or so and completed my lower when it came. Was still waiting on my stock, however, which came in today. So I go to seat the buffer retainer on the spring and it would not go down all the way. Upon inspection, low and behold there it was: the bolt catch plunger wedged inside the buffer retainer. CSB, the more you know gif, etc.
