will the old early m16 furniture and the triangle hanguards fit on the standard 20 inch a2 ar?
It's the little piece of metal directly behind the front sight base. It's the piece the handguards fit into. If yours is triangle shaped, your GTG. If it's round, (not likely) you'll have to change it out for a triangle shaped one. It's clearly visible in my pics.can u post a pic of the hanguard cap so i know what i need ?
