The USMC armorers manual I have gives the specs to fabricate both a piviot pin instalation tool and a removal tool. The installation tool I don't have the resources to produce, the removal tool is pretty simple. Is the a commercial source for an installation tool, or, perhaps a "two-in-one tool? |

The clevis pin is a good idea indeed. When I looked at the drawings in the book, it was very "machinist oriented" as in "+ or - .004" or whatever. I'm a woodworker, thsat kinda stuff gives me angst! [%| ]I was under the impression that the needed diameter was not found on something easily obtained...... |
.
The clevis pin holds the spring and detent in the compressed position, allowing you to put the takedown pin in with virtually no chance of it shooting off someplace. It is a slick, cheap, effective device. Insert clevis pin, line up holes, drop in spring, then detent, compress them, rotate clevis 90 degrees, insert takedown pin from other side using it to push clevis pin back out. |

The clevis pin trick is indeed the way to go. No razor blades to worry about cutting yourself. No working under sheets, no working inside plastic bags, and no spending money needlessly on something that can be obtained at a fraction of the cost and works just like the more expensive tool. Why everyone who builds ARs don't do it this way is beyond me. I guess some people just do not want to change the way they have always done things even if their way is inconvenient or outright risky or think there is something sexy about using expensive custom tools to build their "custom" AR. The entire pivot pin install using the clevis pin tool takes all of 30 seconds to complete. The only down side is that you take "the hardest part of the build" and turn it into a non event so there is not going to be any great since of accomplishment like there might be if you play with razor blades under a sheet while holding a flashlight in your mouth and working inside a plastic bag.

+1 to the almighty clevis pin! I just discovered this trick a little while back on this very website and I will never go back to the old way of doing it. |
+1 on this technique. I start the pivot pin with the groove up until I capture the detent and the pivot pin is in the first lug. Then rotate 90 degrees and the pin snaps into the groove and captures the pivot pin. As an extra precaution I do this inside a 2 gallon ziploc bag. Takes 5 times longer to describe than to actually do this. |
