Description
RetroArms CNC receivers are manufactured from one block of aircraft aluminum (Dural) EN AW 7075 T651 on our multi-axis milling machines. The strength of aircraft aluminum EN AW 7075 T651 is 550MPa, standard construction steel has only 390MPa. Our receivers are not from cheap zinc-aluminum casted alloys, they are completely milled from one solid block of aircraft aluminum (Dural) EN AW 7075 T651.
