Just picked up my Lower!! SWEEEEEET!! It's pretty nice, can't wait to get the rest of the stuff and put it all together. It's like Legos for Big Boys!! KICK ASS!! 
Yup, get it over to Nikkon for proper staking and lubeSounds like your new lower is a POS. Send it to me for further testing.
Haha... Exactly!Yup, get it over to Nikkon for proper staking and lube![]()
A little advice after using their guides for my first build.... Their thread has one guide using vice grips to push in roll pins rather than tapping them in with a hammer. I tried it last week. Don't waste your time. It's great in theory but the only scratch I put on my new gun is from the vice grips which were well taped up. IMO use a hammer and proper size punch to do it. It worked better and didn't damage anything.Now I have to wait for the wife to finish watching Desperate Housewives on the Laptop so I can pull up the AR15.com "How-to" threads.
Those pictures are a lot better than the ones on ar15.com.here is another how to with more pictures and cruder language lol

Also, when you put in the pivot pin detent, do it inside of a plastic bag like a gallon size zip-loc bag. Otherwise you'll likely be without a detent and maybe you're eye. And looking for a chunk of metal the size of a grain of rice in my besement workshop was not fun.

I saw the guide and thought it was a great idea. Then I proceeded to scratch my brand new lowerI've had better luck with the vice grip method than the hammer/punch![]()
Normal and congratsOne question about the charging handle... after I pull it back, I can push it forward with no resistance and lock it in place...I'm guessing that's normal?
I bought the installation toolit took FOREVER to get that sucker in there
