| Hi all...I bought an SP1 rifle today, serial #174xxx, 20", birdcage, Triangle HG's. A1 sights which I assume is correct, think this is an all original rifle. Paid $1000, it is a little dinged and dirty, but not bad. Say, 90%. How did I do on the price? Also, where can I go to find out info on this gun, original build configuration etc...? Thanks |

Produced around 1983. Here’s part of my old rec.guns faq on the SP1. The Colt AR-15 model SP1 (cat.#R-6000) was in production from 1963-1985.
