Early Colt "Many-Circles" magazine button, used throughout 1960's Colt AR-15 production. These are original surplus magazine buttons and are correct for virtually any early Colt build from the 601 to XM177 and everything in between. These can be distinguished from regular M16A1 magazine buttons as they have more "rings" engraved into the face of the button.
These are genuine surplus parts in good to very good condition and will show minimal signs of wear/use and feature a nice original gray anodized finish. Condition options are available.
