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.

    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.
