Well everything has gone pretty smooth up until this point. I am having trouble with the Pivot pin, Take down detent and spring. This thing has been an unholy bitch, I all ready lost one spring, it is somewhere on the carpet, luckily I have two extra. Is there any tricks of the trade for getting this damn thing in, I have been working on it for over an hour. Also in putting in the rear pivot pin (I managed to do this one pretty easy) it locks in place either open or all the way in. From what I can figure the pointy end on the take down detent goes into the channel on the rear pivot pin. Well this is all fine and dandy but the thing will not release from the little hole, thus allowing me to either take off the upper or put it on. Is there anywhere that has detailed pics? Or video? Last this is all for a AR pistol build. I have gotten all the accesories I need including the pistol recoil buffer. However I can not figure this thing out. How does it go together? The buffer is nothing that I am used to seeing on an AR and I have no idea how to put it to work, nor how to keep it in the tube. The way it looks now it the spring will be in the upper receiver. Does it use a standard buffer? I would not think it would? HELP!!! |
They can be stiff at first, just tap it open with a plastic punch or something and close it again - repeat a few times and it will work fine. |
Well that is pretty much the best that I could figure on the rear detent, it must just be stiff. Now onto the pistol buffer. How does this thing go together, there were no instructions with it. What I am wondering is what holds the buffer back? I am sure there is something I am missing, but for the life of me I can not figure this out? All I have ever dealt with is the standard buffer and a telescopic buffer, both essentially the same. This new pistol one has me baffled.

There is a buffer stop pin, and spring.. Taken from the guide here on ARFCom. 9. Thread the rifle/carbine buffer tube slowly into the receiver... taking care with the takedown pin spring. The tube should be threaded in just up to the buffer hole.... and then insert the buffer stop pin and spring:  Then thread the tube a little more, so that it holds the pin in place, but does not touch the center part of the pin and bind its movement:

| I appreciate the pictures FlyByWire but I have the tube on, that is not the problem. The problem is that the normal buffer that you would use with a rifle or carbine is nonexistent in the pistol buffer format. This is what I am not used to and do not know how to make it work. What appears to be (from pictures I have seen) buffer looks like a long cap in which the spring would go inside. However this cap is a lot smaller than the circumfrence of the tube itself. In other words once I get some spring pressure behind this, I see no reason for it to not jump (after one round) and end up somewhere in the upper receiver with the Bolt. Now I know of course that I am looking at this from the wrong way, but I am having a hard time at being objective and thinking this one through. If someone has a pistol lower and could show some pics I am sure this would be cleared right up and I would be able to get it right? Thanks Eric |
Pistol eh, sorry.. My bad |
