Need rear pivot detent pin

[mx'r]

Did my first AR build today and lost the rear pivot detent pin. Found the tiny ass spring, but cant find the pin. Thought it was in and seated but I thought wrong. It flew away I guess. Anyone know if a vendor at the Tanner tomorrow might have one? I'm sure it costs about .002 cents, but I'm dead in the water until I find it.

There should be at least one "misc AR parts" vendor, but if you don't find one Bowers' should have them.

There's usually an AR parts guy at the show but I can't think of the booth name- he's always there though. [Beer]

Got it at the show for $1.00 . Guy selling all the Black Rain stuff all the way in the back. Didnt catch the company name, but nice guy and great parts selection.

Yeah, he's the guy with the engraved port covers. Gotta love 'em. The daughter also had a fun chat with Rain's daughter.
