"Slick Side" upper- no forward assist or brass deflect
Guys,
I scored another upper w/o the brass deflector or forward assist. :super:
I have debated on going the M231 route (now the sights wouldn't be correct in this case, but could be closed up).... or make an early SP1 clone.:confused:

The lower would be no problem if I go with a slick/ slab side build. I would go with a Tactical Machining 80% and zip off the offending protrusions.:cheers:
Oh, that cool mottled finish was due to the primer and paint that was applied! Sorta like a camo coating to keep buyers away!:lol:
Used to purchase these Colt SP1 rifles in lots of ten at $219 each
Back in the early 1970s when I had an FFL, the going price for those slab side AR15 Colt rifles was $219 each in lots of ten. The going rate for a single unit to a dealer then was $229. A pal of mine would buy ten Sterling built AR18 rifles and then we'd trade five for five.
Some of those Colt AR15s without forward-assist were just a hodge-podge of then obsolete and otherwise scrap M16 parts thrown together into complete rifles for commercial market sales. Others that became available to civilians from older stock, were in fact very early AR15 rifles that were built with the intention of easy conversion to M16 military rifles. While working for a defense contractor in the mid-1970s, part of my job was checking in weapons to be used for testing purposes. Would sometimes have a half dozen M16 rifles sitting out on my desk. While munching on a sandwich I'd spend lunch time examining the weapons. Remember being intrigued that on the left side was the rolled Colt logo with AR15 model designation. On the right side was deeply stamped in larger size font "M16 and just below "5.56 NATO". Of course the selector switch on those M16 rifles turned all the way around so to point at "SAFE - SEMI - AUTO".
Those early civvy AR15 rifles had a lower receiver that, except for the selector-switch stop nubs being ground-off, was identical to the selective fire M16 version. To transform one of those first edition AR15s into a rock n' roll genuine M16 was by swapping out a few then easily available internal components.
It's quite interesting to me to see people scrounging around these days for beat up parts in order to "restore" the things into vintage SP1 Colt AR15 rifles.
