Every time I open my new build the buffer spring and detent fly out.
The buffer detent spring has a solid pin inside the spring, is that supposed to be ther? What gives???????????

At first read, I'd say your buffer tube is not screwed in far enough, it's supposed to be in far enough to almost be touching the tip of the buffer plunger, and that is what keeps the little spring loaded monster from shooting across the room.
check the build guides and youtube vids to see what you may be doing wrong during your setup, screw the buffer tube in to hold down the pin, then run your locknut up tight to the buffer tower. Let us know if this fixes your issue. Second read, you may need to show us a picture so we know what pin your talking about, the normal buffer Detent (plug) sit's on a small spring in a vertical position, think a cap on the top of a small spring, as mentioned above, you screw in the buffer tube to hold this little cap with a point on it, down and captive. The buffer stays locked behind this little cap/pin if installed correctly. |

This.... and possibly a spare roll pin from the LPK ended up inside the spring not causing it to compress? Quoted:

Sounds like your receiver extension in not screwed in far enough... This.... and possibly a spare roll pin from the LPK ended up inside the spring not causing it to compress? +1 This. Oil-coated tiny parts love to hide inside of other oil-coated parts. Also, the little c-clip in an ejection door kit can sometimes be undetectable. It could be stuck on or inside the door hinge lip, package, etc. Takedown and Pivot detents sometime hide out in the channel of these pins. I have found small springs riding inside larger springs. It can be a little confusing until you lay everything out and take inventory. I thought I was cheated out of a hammer once, found it migrated inside the grip Remove the pin, it does not belong there. Screw in buffer tube to capture the buffer plunger cap/spring. Tighten castle nut. Check buffer plunger to see if you can now depress enough to release the buffer and spring from the buffer tube. |
