My son just took the AR we built from a stripped lower out to the range. Two problems surfaced. One was that the trigger pin that the trigger rotates on kept backing out to one side. This was after about thirty rounds or so. Then a spent case got stuck in the chamber. Not a big deal as we took a cleaning rod and a light tap pushed it out. My question is, aren't all these parts supposed to be machined to mil spec? Could the trigger pin be a little small in diameter? It did slip in quite easily. I don't remember what LPK we used.

Make sure the hammer spring is installed correctly, the hammer spring should rest in the outer grooves of the trigger pin and hold it in.

In other words, the hammer spring legs should sit in the grooves on the top of the trigger pin.

I'm looking at it now. The "legs" are just laying on the floor of the lower receiver.401765

Looking at the picture you posted, you can see the grooves that the legs are supposed to be in...it's an easy fix..

Pull the hammer out, put the "legs" in the right spot, put it back together.

Problem soved...

Kns makes anti rotational pins to completely erase this issue as well. If you wanted to go that route.

Get to know your dental hygienist...Mine gave me a handful of old tools and one of them works perfectly for lifting the spring legs. ;)

or a set of plastic picks (if you don't want to use metal)... pretty much all gun retailers have them, but here's PSA: http://palmettostatearmory.com/index.php/gunslick-gun-cleaning-swabs-picks-doubl-end-brush-gunslick-91924.html

They are pretty rigid and durable - and are great for cleaning too.

But with the retard search, you're the only one that knows where that is at...personally, I wonder why peeps don't get some instructions on how all those springs and things go together...it's not a 'it only goes together one way, the right way' kind of thang...

It's a quick fix. There are plenty of youtube videos on lower assembly to show exactly how it goes in.
