Colt SP1 AR15.  This one was made early 1974, all original in very good to excellent condition.  It has an excellent C MP B marked barrel which were fully chrome lined.  Trapdoor buttstock and original silent sling and early Colt magazine with an aluminum follower.  Bolt carrier is C marked and the bolt MPC marked with the hash marks behind the lugs.  Has some marks and rifle rack wear, no cracks and all of the teeth are intact on the handguards. People talk about only shooting 223 through it, but the SP1 used the same barrels as the M16s, so 5.56 55gr ammo is fine in them.  The SP1 lower will accommodate an FRT too, no block.
