Default AR15 Assembler check list

I know there was a list here at one time. I can't find it, so I just made another one. Several people have asked for one, so I figured I would just type one out. This is basically from memory so PLEASE if you spot an error tell me so I can change it. Copy this, paste it and print it. Then use it while you are buying all the parts for your next build.

The major Assembly is on the left, parts inside that assembly (SUB-ASSEMBLIES) are under tabbed to the right. So you can check to see if the part you are buying has all the sub-assemblies needed with it.

ar15builderpartslist.pdf <-- needs check box for lower itself, but isnt that big a deal This is for printing
AR15-SchematicPDF.pdf <-- Very nice visual ref.

Plz see post #4 for a clean copy of this,
#16 for an updated PDF file
Post #20 for a PDF with computer check boxes
and Post #24 for Brownell's own order form, its 14 pages long, this single page makes a great cover page for that!!!!

Good luck.
