Early Colt SP1 Rifle

[RCS]

Photos are from a Colt SP1 with a three digit serial number, rifle still appears new and the original owner
had stated that he never fired it. Nothing has been changed only the small white dots were removed from
the magazines. Sling is Colt

some of these photos will not upload - states "file is corrupted" ?

Amazing, Robert!!!
Where do you find these things!!!???

As for the photos.......four are showing up in the thread. Do you have more to share? If so, you can email them to me and I can try to get them in on my end.

It says 4 photos, however you see 3 in the post. When you click a pic too see better details all 4 do show up. I might just be that's all you can fit on the starter post?

Robert,
With a three-digit serial number, what year would this rifle have been manufactured?
Thanks,

This three digit Colt SP1 was manufactured in 1965

Just like collecting M1 rifle en bloc clips, collecting AR-15 magazines is also interesting

It sure is. Those early Armalite mags are really neat!

[CCyooper]

Yes those waffles are neat!

That mag is cool, I've never even seen one. Thanks for that pic posting up!

The magazines that came with my three digit Colt SP1 had the small "CAL. .223" and a block inserted so only five cartridges could be loaded

I recently saw one of those early Armalite 'waffle' mags sell for just over $300.00!!!

I have a few 20rd Colt mags. The floor plates are marked with the std. Colt nomenclature with two exceptions, the CAL. .223 floor plates are attached too unmarked bodies that I suspect were for commercial and civilian rifle sales. The CAL 5.56mm floor plates are attached too Universal Industries bodies that I assume are/were USGI for the M16. Both magazines have the Zinc followers and have been 100% dead nutz reliable. I prefer the straight bodies too the current semi curved/chopped down 30rd too 20rd mags that are on the market now.

the first 30 round magazines only had a slight curve and started to appear around 1969. This magazine was still in the original envelope and is sterile, these fit both AR-15 and AR-18/180 rifles

[Phil McGrath]

That looks like it could pass for current production it looks that clean, I wonder how it compares too the current 30rds profile? I know if you chop off the top 10rds the lower curved profile look pretty severe. That's why I prefer the straight 20's.

Sorry but a 3 digit SP1 would be 1964 manufacture. 1964 closed the year out at approx SN 2500. I own an unfired in box with all accessories AND a made in US Colt (actually made by Realist for Colt) scope acquired from the original owner. I sent in for the Colt historic letter. Mine is SN 118x and was manufactured Nov. 16, 1964 and was shipped out on Nov. 20, 1964. Here is a pic of mine that was loaned out to answer a Q on one of the other forums and ended up on arfcom.
