| Sorry no pics. Why buy a tool you'll only use once or twice. All I used was an hobby knife and tweezers (wear eye protection). With the lower facing up (butt stock down, mag well up), install the detent spring. Pick up the detent with the tweezers and place it over it's hole and hold it in place. With your other hand, use the blade of the hobby knife to push the detent all the way down. With the hand that was once holding the tweezers, insert the pivot pin. Pull out the knife blade. This works because the blade is thinner then the gap between the flat side of the pivot pin. Hope this helps some one and saves you a couple bucks. |

I use the clevis pin method. No worries about launching the spring. I did this ... got one at Home Depot for like .75 cents.

They make a tool? Yep

| I just finished my first lower using a razor blade. I was going to buy the install tool but got impatient and just used a razor blade. I launched it once but luckily found it without too much searching. I'm positive that I would have got it the first time if I didn't get distracted by my two year old. |

I have done quite a few builds this way, still have managed to launch the detent. Bought a clevis pin for a buck & have not launched one since.

| I've been laying the receiver down on its side and installing the pivot pin with part of the round side pushing the pin into the hole then as I get the pin in further I turn it til the pin pops into the grove, job done.... we don't need no stinkin' tools for a simple job like that. |

This guy gets it. Pivot pin installation rivals trigger guard roll pins and lubrication as the two most over thought out and easy tasks made difficult that get discussed ad nauseum on this site. |

THIS ^^^^^^ It's in our assembly sticky, too. ^^^^^^^^ First build, first time. No knives, tools, expense, hassle. Done. If some would spend as much on reloading equipment as assembly tools, they could shoot more often. |
| I used a punch the same diameter as the pivot pin, get detent down in the hole, push the punch over top of it through the holes, going backwards, and then push the punch back out with the pivot pin... simple, had no issues whatsoever. This was my first build(took about 30 minutes) and I heard all the complaints of launching things across the room... I was scared, but now realize that it couldn't have been easier. |

Exactly what I did for my first build. |
| Or you could just go with the KNS push button take down and pivot pin set and forget the silly detent all together. Looks good, works good, makes life real easy. Although I really do like the suggestion about using a dowel rod with a hole drilled in it. Thats very clever. Think I'll have to do that for my next build. Bravo sir. |
