Colt SP1 6001 carbine

Here are the pictures of my Colt SP1 6001 carbine. It is nicer than I originally thought. The slick side carrier and chrome bolt are a really nice touch. The chrome bolt a surprise.

There is next to zero wear on any of the internal parts!

I was really surprised to see the old style funnel shaped pin.

The butt stock has one small spot that shows wear. It is not near as bad as the photo shows.

The muzzle is not the slightest bit worn.

Sportsmans Guide has some Colt mags if you need more.

I was looking over the 20 round magazines I have and comparing them to the magazine that came with the carbine and notices the pop rivet. Wondering what the heck I started putting rounds into it and sure enough, only five will fit. Is this how Colt did these? I know that all the books say they came with a five round magazine but I have never seen one. I have 15 Colt 20 rounders and none have the same round hole in the slit of the floor plate. I tried to remove the floor plate and it won't budge. I also noticed the five rounder that came with it has a small tab broken off :( Does the rivet need to be removed to remove the floor plate? I have no intention of messing with it at all, just curious.

The rivet comes out and the little tab needs to be pressed in. They built a frame inside from steel strap to limit. That old style firing pin retaining pin is sure an oldie...

Mebbe we need a SP1 thread? Think I will scrounge mine up for a closer look. Thanks for the pics Bill.

That whole BCG had to have come out of a 1960s rifle.

Roscoe, after some extensive reading on these carbines, they could have any BCG in them. It was a hit and miss thing. The carbine came out long after the advent of the forward assist but for the SP1 rifles and carbines the general consensus is any of them could have either BCG with or without the FA cuts, with or without a chrome bolt. I feel fortunate to have gotten the early configuration bolt.

You also have a non-notched hammer. I'm surprised there isn't a three prong flash hider as well!

It strikes me that the bolt carrier isn't cut back on the bottom, either. Or is it that it just isn't cut back very far? Not all that many early semi-auto guts show up in these parts, so a little education on my end probably wouldn't hurt!

Here is a better shot of the BCG and FCG:

The disconnector looks to have been broken and patched at one time...

It's just a flake in the finish. There was some rush in the channel and around the spring. I'm glad I took it apart and cleaned it good.

Long tail safety sear. There's got to be some sort of chronological sense to these...or no? What's the safety look like?

I thought in the beginning they had the long tail disconnectors because without the full auto sear, it didn't maker any difference. In the beginning there was auto and not...and no one cared...?? It also has the open ended trigger tail. That changed later.

It looks to be a standard AR safety, not the M16 with all the cuts.

Yep. I tried drilling mine out but haven't achieved it yet. It's pretty hard. I just set it aside. I have other 20 rounders.

That's a really nice carbine. Those stocks alone are worth a small fortune. Well, not that much, but they go for a good amount of money. Over 200.

Bill, sweet carbine.. It is identical to the one I had in the late 80s. I registered it with the original 1990 AW bill in California. I sold it in 1999 after I got forced out on disability retirement.

That is nice to know. I sent an email to a well known retro black rifle guy with some questions but he did not return my email. Do you remember the serial number? And, it had the same bolt configuation as mine? (slick side phosphate, chrome bolt and old style firing pin retainer pin)

Those are Colt commercial mags not USGI, you can drill out rivet
Nice SP1

Bill, I see if I can find the serial number. Mine had an M16A1 BCG when I got it. I doubt that it came from the factory that way, though.

My SP1 rifle came from Colt with 20 rd mags that had the capacity limited to 5 by means of a U-shaped piece of sheet metal under the follower. Easily removed by removal of the floor plate.

I drilled out the rivet on some Colt 5 rounders, shortened the "U" limiter and made 10 rounders out of them. Once the dumb law passes and I have to register them, the number of rounds in the mag is irrelevant, and I can take the blocks out.
