my first ar 15 build please help...
Hello every one . Like the title says I am building my first ar 15 and need a lil bit of help.. the problem im having is that I want to build it in the 7.62 by 39 caliber.. I already have my lower complete and I have the stripped upper now the question is what kind of bolt or bolt carrier assembly do I have to use or what parts are going to have to be different than a regular 223.. or can I use all of the regular parts of the 223 and just change the barrel
my fear was thrown along with my last diaper..
