Some detailed photos of a three digit Colt SP1 from 1964, both the sling and magazine are original to this rifle. There are early features that were changed during the four digit production, the front sight base being one of the first along with the thin barrel. The gas tube is not steel. The early buffer continued into the four digit production.Attachment 54818Attachment 54819Attachment 54820Attachment 54821Attachment 54822Attachment 54823Attachment 54824Attachment 54825Information
