Hammer has circle C with circle 7. It had rifle handguards on it that I swapped out to triangular. Have some questions though. Did these ship with the A1 FH or 3 prong?
Was the delta ring the flat style or the tapered style? Were the HGs triangular or rifle? Did the stock leave the factory with a trapdoor? Not sure what was changed or updated, I think it's still in factory config except for the HGs, I think the triangular fits it's personality a lot better. AZ, USA.

Colt took two directions in. The Colt SP1 shown here is one of the earliest available AR rifles offered to the general public on a wide scale.
Colt took two directions in marketing this rifle: As this was an era where gun ownership was typically equated with hunting, the rifle was marketed to private citizens as a lightweight, space age sporting arm. For law enforcement, it was marketed as an accurate, handy, powerful and light recoiling carbine. Colt sales reps would even place the stock to their chin and fire off an entire magazine in front of police officers to demonstrate the light recoil.
The reason for the slabside and slickside nicknames by collectors. Photo: Francis Borek. Unfortunately, memories of the recent war in Vietnam were still fresh. Among those memories was the utterly disastrous introduction of the M16 into service and how that could be seen as a metaphor for the war itself.
Thanks to problems with the ammunition and the idiotic decision not to issue cleaning kits, the M16 initially gained a poor reputation. The rear sight only adjusts for windage. The markings also indicate the upper was forged for Colt by Kaiser Aluminum. Though it may sound strange, the AR was not once the universally accepted rifle that is today. Although this is an AR rifle, it is a bit different from what most shooters are familiar with these days.
Outwardly, the rifle looks like most ARs, but as one comes closer the differences are apparent. Gone are the forward assist and shell deflector making this a slick side upper receiver. The rear sights are only adjustable for windage. This solid stock has a hard rubber buttpad, a sling swivel instead of a fixed loop, and no provision for storing a cleaning kit. The handguards are triangular shaped and probably the most distinctive feature of the rifle. They provide a solid flat surface when resting on an object and are heat shielded.
Some might not find them comfortable. Conversely, some may find them to be the most comfortable AR handguards ever. They are also inconveniently separated into distinct left and right halves instead of symmetrical halves which can be used for either side. Back in the day when you only had the M16 or M16A1. The thin pencil barrel is chrome lined and features a glacial twist rate of 1-in inches. The A1 pistol grip lacks the annoying finger ridge found on the A2 grip, and has a provision for a sling swivel.
Finally the lower receiver is a slab side receiver, lacking the magazine button fence. The rifle is all original, just as the day it was delivered. One other difference is that the forward receiver pin is actually a pair of screws. It is unknown why this is so, but there are two prevailing theories: The first is that the US Army asked Colt to do this in order to prevent soldiers from stealing upper receivers and using them on privately owned SP1s or vice versa.
