Acme North has a limited edition Aero Precision ghost gun marked lower which was the basis for a nice AR 15 build in 5.56mm
This rifle features Magpul furniture incl a fully adjustable stock, BCM charging handle, BAD lever, EZ take down pins, RF marked upper receiver, Anderson bolt carrier, Diamond Head free float hand guard and enhanced trigger guard.
Note: the receiver and selector markings are a reference to a ridiculous interview given by a California law maker where he references ghost guns, 30 caliber clip banana magazines that can be emptied in 1/2 second and other foolishness.
Item number is G-67893-3
