Anyone familiar with the quality of AR-15 parts and especially the upper parts gun kits from American Spirit Arms at www.gunkits.com
I am building a California Legal FAB10 (flat top with 24 inch barrel for target shooting) and need a source of AR-15 parts. The complete upper kit with everything to finish the FAB10 (including trigger and recoil buffer parts) is included. They have a gun show presence in So. Cal which is nice (Arizona company).
