Yes, the safety selector detent is pointed on one end too and the point goes into the safety. The detents I'm speaking of are the takedown and pivot. Is my Model1 kit, they are not pointed at both ends. I too launched one of the detents across the room, into the ether/another dimension some where, never to be seen again. So, in preparation for launching another one, I bought a DPMS pin kit. It's detents are pointed/rounded at BOTH ends.
I did notice that (for the takedown detent) that it was almost impossible to move the takedown pin when I used the pointed end INTO the takedown pin. A little lube might have helped, but it was VERY hard to used. With the flat side into the pin, there was a bit of resistance, but the take down pin was able to move.
Anyway, I'll keep the pointed end into the spring. Thanks for the help!
