Original Colt complete Rear Sight Assembly for all Colt AR-15 / M16 / M16A1 models before the introduction of the M16A2 sight in 1983.

These are used 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 and Daniel Defense A1 Rear Sight Units.


Notes on Options:

- If is our belief that the smaller sized font on the Wheels are earlier Generation Wheels, possible Gen 2. Larger Font is likely a later version. Understand this is not verified, just our guess as of now.

- Choose Black or Grey to better match the color of your Upper.

- Battlefield- Will be damaged, numbers may not be visible, may have chipping, may be discolored (no preference will be given to type of damage)


We also offer these parts individually:

    I called RetroRifles to enquire about the products I saw on its site online. They answered immediately and the person on the Phone was very friendly, knowledgeable and professional. I immediately ordered the items and they were shipped almost instantly (less than an hour). It took only a few days from Reno to Ontario Canada and it would have arrived earlier because we just had a long weekend holiday here for Canada Day. I am impressed. The Colt A1 Rear Sight assembly will look fantastic on my build. I also ordered a Triangular Hanguard. It is very sturdy and beautiful ! I am more than happy. RetroRifles is my place to go for Retro Parts when I can't find them up here in Canda. I definitely recommend RetroRifles. After Talking to the man on the Phone I deducted that he loves and knows what he is doing and this was more than enough for me to decide to order without hesitation.
    I send many many Thanks from the North.
