"Alright. We've got our upper receiver attached to our lower receiver and we've got our bolt slid in right here. Now this right here, this part of the whole process is the trickiest part is the reassembly of this main spring housing. It can all go back together just fine but be just a booger to get it done. So what we're going to do is I just kind of take this main spring housing in my right hand here and I kind of balance that bolt pin stop on my index finger. And what we're going to is we're just kind of slide this in here. There you see it kind of slipped out there. And you're going to let that bolt spring slide up. And its going to be some pressure so what I do is I take my right hand and I just kind of grasp the bottom of the main spring housing and I grasp the top of the receiver and I just kind of push up. There's a little bit of pressure there. Don't feel that as if there isn't. It can be a real tight fit between the lower receiver, the upper receiver and here in the very top where your catch is. We're going to do one more little pop there. And as you can see, here's our bolt pin stop sitting right outside of the top of the receiver. And so now we know that this mechanism or this main spring housing is in there, the bolt pin stop is inserted correctly. So the next thing you're going to do is you're just going to kind of look in the top here. As you can see there, you can see our hammer strut sticking out right there. Now that hammer strut has to reengage the plunger here for this whole action to work. So I'm just going to take my light here and I'm going to give a quick little shine inside here and I'm going to make sure that my hammer is in a fired position or an up position. You need that hammer to be inside the bolt. So I'm going to take a look and see where we're at. I'm looking. It looks like its in the up position. We're going to swing this down. Alright, we're going to check one more time here that main spring. There we go. Like I said, this can be a difficult part for most people here and its a difficult part for me sometimes. I joke around that this is my arch nemesis is this last step in the reassembly of this Mark 2 because that main spring strut and your hammer have to be in the specific location for this action to work. As you can see, we're going to reinsert, this is just going to slide back in, and its going to be tight just like it was when we took it apart, but its going to be easier to insert simply because you're just pushing it back in and you're not pulling it out by this lever. We're going to insert it here and you see here we are flush and we're just going to take this lever and we're going to put that lever back in there. And right now, we have an assembled firearm but what we're going to do is we're going to do one more check."
