Parts interchange with ar 15

No. Parts will not interchange with an AR15.

Trayce, for the most accurate information on possible AR parts compatibility, I would ask ARMALITE Customer Service at 800-336-0184 or 623-780-1050 M-F 7am – 4pm MST.

Different gun .. but sort of, kind of slightly similar. Even the magazines won't interchange without modification. The AR-18 is a piston driven system. The biggest similarity is probably the name "Armalite". Trigger groups are said to be 'the same' ... bu
