Hello I am new to the Gunsmith group and I am still getting a feel for the site, Any suggestions and advice anyone can give me is welcome! I am a novice DO IT YOUR SELF kind guy, I have some physical impairments but still love playing in my shop. I would love to find some new sources of drop forged lower receivers For AR 15 and or M 16 also AR 10 .308 stuff. I also enjoy my old rolling block Sharps 45-70, But have not had the opportunity to compete in some time now.
