I'm installing a Palmetto State Armory lower parts kit into a stripped Spikes lower receiver. This is my first build from a stripped lower. Everything seems fairly straightforward, except the rear take-down pin and detent pin. I installed the rear take-down pin, slipped the detent pin (both ends are equally pointy) and spring into the hole on the rear, and installed the locking plate and castle nut. Everything seemed to go together as expected.
However, when I checked the rear take-down pin I noticed that it did not seem to lock into place when fully in or out. The detent pin just barely prevents the take-down pin from falling out, but doesn't seem to stick out far enough to make contact with the dimples on either end of the take-down pin slot.
In looking at the detent pin, it seems like it should pass all the way through the hole from the rear, and press fully onto the take-down pin. But my detent pin seems to only peak out of the hole, preventing it from fully making contact with the take-down pin.
Can someone confirm, is the rear detent pin supposed to be captured inside the slot, or should it be free to fully exit towards the front into the slotted take-down pin?
