looking for a little schooling on building my 1st AR....

jmac3434 · Mar 7, 2011

So i have decided to put together an AR from scratch, I do have firearm experience but this being my first ground up build I am looking to have someone check my work and able to kind of walk me through the rest of the process. I want to be completely sure this riffle is in safe working order before shooting it. Upper and lower are complete and the barrel/FF rail/ & gas assembly will be here in a few days. So anyone out there with a lot of AR building experience would like to help me out it would be much appreciated!

here is how it sits as of now...

Assemble your own LOWER, UPPER, FREE FLOAT, TRIGGER, GAS BLOCK - Step by step instructions! - AR15.COM

I sat down on the floor with the laptop during a football game, and went slow. Had it done before halftime.

The Lower parts kit will be fairly straightforward, and doesn't require tools. Putting a barrel on that stripped upper receiver will require an AR-specific wrench, and an action vise (both available from brownells or midway).

Have fun.

If you were in Eugene I'd help ya out. Hardest part of LPK's is the front takedown detent and bolt catch, but maybe that's just my fat fingers!!

Brownells has a free multi part video on AR15 builds.. I am using it for my first solo build and it has been of great assistance. I used Download Helper in Mozilla to save it to my hard drive and I can now start and stop it any time, anywhere in the video, off line

Buy some 100 MPH or Gorilla tape to mask off parts of your lower to protect the finish as you assemble

as you can see in the pictures, the upper and lower are already assembled. I was looking for some check the head space and help install the barrel and FF tube since i do not have the tools for the and maybe take a peak at the rest of the gun to check my work.

As long as the barrel came with the extension installed the headspace should be good to go. Very rarely is there headpsace problems unless you mess with the extension. Find some one with a good FF wrench and an action block and the rest is easy. Those are the only two specialty tools I needed to do my AR
