Colt factory magazine block from early AR-15 rifle
When Colt started selling the AR-15 Sporters to the civilian market they placed a magazine block in their magazines that only allowed five cartridges (for hunting).
Interesting to collectors is that not many of these magazine blocks are found today as most were soon thrown awayAttachment 96104Attachment 96103

also the early AR-15 bolt carrier
Found this early bolt carrier (center in photo) in both three and four digit Colt SP1 semi auto sporter rifles. The machining is quite different from the common full auto and semi auto bolt carriersAttachment 96105
