Complete rear sight assembly for all Colt AR-15 / M16 models before the introduction of the A2 sight in 1983.
Authentic Colt parts that came off old rifles; in good condition.
This is the set of rear sight parts you need for a multitude of upper receivers, as well as some stand alone rear sight units - including Canadian C7/C8 builds using the C7 (M16A1E1)upper receiver.
Made in USA
Note: Very limited supply.. When this small stash is gone we do not know when we will have these again.
