Hi everyone,

Been lurking and finally bought a RRA Lower and J&T kit and putting it together. Thanks to everyone here for all the information I have read. It is making my build go much easier. One question though. The Pivot Pin Detent has a flat end and pointed end. Do I install the pointed end in or out?

Thanks all,
John B
PS Did a search, but limited to 30 days and did not find any info on it.

I'd like to know too, the instructions on this sight for assembling a stripped lower does not specify. It says the pivot pin detent is usually rounded on both ends. Maybe you are looking at the selector detent, double check to make sure... Perrito

Pointed end should go toward the pivot pin and away from the spring. Most that I've seen were pointed at both ends. Another common problem is that manufacturers don't always clean the debri from the detent spring hole. You should clean it out by hand with a drill bit. A cheap tool to help install the spring and detent is a 1/4 inch diameter clevis pin available for about $1 from most hardware stores. They come with about the right size hole drilled through them. Bushmaster sells a nice tool if you expect to do more. Someone here suggested installing it with the lower inside a clear plastic bag or standing in the bathtub with the shower curtain closed. I just do it at my desk but confess I've lost one before. Finally, I have had some springs that were too long and would not compress far enough. Some guys simply trim off a few turns but I've always found correct ones. I keep a few spare springs and detents around.
