My lpk from PSA includes a front takedown pin that (at an OAL of 1.318") appears too short (by maybe 1/4" or so) for my Aero lower. Am I missing something? Isn't this a standard part? The upper fits properly to the lower at the hinge, and the rear hinge pin from the same package appears at first glance to be okay in length.

NM, the pin goes in the other way! Great big 'ol DUH!

The following complaint still applies though!

Also, the lpk did not come with the front pivot pin install tool. Launched one detent and spring into low earth orbit and had to walk away. Boo!

Advice? Assistance? TIA!

That looks a lot easier than the way I was trying to do it! But then I thought the pin was too short when I was putting it in bass-ackwards. :oops:

Thanks for the link @beamernc !

Hey, it's my first time building a lower! The way I work, I'm lucky to still have all of my digits intact! :D
 
use the clevis pin trick and also a small 'garbage' bag to contain the shrapnel...

Press the spring and detent in flush with a small flat screw driver from a glasses repair kit and then slide the take down pin in place, removing the screw driver only when the pivot pin is in place to catch the detent and spring and then lock into place

Yeah, low earth orbit using this exact technique. :(
Eventually found the spring, surprisingly. The detent, not so much.
This technique is highly susceptible to the JT Jitters Syndrome. o_O

I do it this way except I use a thin metal putty knife.

Go outside and look towards the sky. One of mine should be passing over any minute.

Ok this reminds me of the joke about the two good ole boys working a constrution job. One was goin thru the box of nails throwing some away and keeping some. His buddy asked him what he was doing. He said some of the nails had the heads on the wrong end. His pal said "you idiot they are for the other side of the house".

At the risk of revealing my ignorance what difference does it make which way the pin goes in as to how long it is?

If you go in from the wrong side, the detent holes don't mate up. It was a real rookie error. :(
 
Threadkiller Update:
Problem solved in 30 seconds start to finish with a clevis pin. Thanks to all for their assistance and/or sense of humor! :D

I keep 2 clevis pins in my parts box. Money well spent.
