Old Colt SP1 and Full Auto FCG???

[goodlookin1]

The carrier is from a later model, (note the cuts in the side for a forward assist)

It's a proper SP1 type carrier ground from an m16 bolt, but it's not correct for that upper.

The thing is, if it's early enough to have the m16 FCG then it shouldnt have a later model bolt carrier.

And since there is almost NO wear on the FCG, it's hard to explain away by 'it wore out'

I'm not saying it didn't happen (some of the early slick side carriers were chrome and some people didn't like the glint while they were out hunting etc. So it could have been swapped out for cosmetic reasons...

But it does set off my 'not quite right' detector.

You definitely can determine year by serial number, I'll look it up when I'm in front of a computer.

As for the carrier, are you sure you were looking at the right one? This is it.



Someone else posted the different carrier types....I'm not seeing the forward assist cuts on this carrier????


As for looking up the serial 3, thanks! I tried looking but couldnt find it.

Looks like late 70's to early 80's....(my guess is 1979)

WAY to late to have a FA FCG

The forward assist cuts are visible through the ejection port on the right hand side of the bolt carrier.

Look at the top carrier in this picture:

Here is what it should look like through the ejection port for a slick side gun:

Thanks AJAX, i'll pass the info along. I guess it does appear that someone put in the FA FCG way back when.....probably back when you didnt have to worry about stuff like this.

Are you absolutely sure about that? The Colt SP-1 Model AR-15 had its own SP-1 Bolt Carrier which was absolutely semi-auto. In other words, it came with an SP-1 AR-15 carrier, not an M-16 carrier, which is what is considered a "Full Auto Bolt Carrier." Here are the differences:

The one on top is an AR-15 bolt carrier (semi-auto)
The one in the middle is a Colt SP-1 bolt carrier (semi-auto)
The one on the bottom is an M-16 bolt carrier (full-auto) ***Notice the firing pin shroud on this one***

I suppose I can't say with absolute certainty that it came with the FA BCG - I'm quite familiar with the difference.

The original owner of the rifle was my father; I talked to him about it this morning and he swears the only thing ever changed was to accomodate the DIAS. My brother is nearly 10 years older then me so he'll have a much better memory of the change then I do...unfortunately I haven't heard back from him yet. I'll update when I do.

The original aquisition story is essentially the same as Flight762s bought new in the early 70s as essentially a nostalgia piece from my dad's time in Southeast Asia. My dad isn't, and never really has been a gunnie...he's owned maybe 5 guns in his entire life and he turns 73 in a couple weeks.

I was the one who posted the 3 carriers. And as far as you not being able to see the forward assist notches, take another look at the first picture that you posted. Now look into the ejection port --




.......Voila'!

DOH!!!

Shoulda seen that.....thanks

Hehe...Great rifle, by the way. Just have him (or you, or someone else) get those M-16 FCG parts outa' there ASAP & swap them with some nice, new AR-15 parts. Maybe a nicer trigger, like an ArmaLite 2-stage Tactical. Inexpensive and one of the best triggers out there for the money.

And, when you buy the whole parts kit with it the price even gets BETTER (that's why they are frequently sold out) -

Except that's not even close to what actually happened....

Maybe so, but that the way that I heard it, and the defense Olofson made (unsuccessfully) at trial. There may well be other issues, I don't know, and I don't want to get off topic. I do know that it was not uncommon for SWG/Olympic Arms and Pac West AR kits to come with FA parts back in the 1980s (saw more than a few like that). That is why Olofson's story made sense to me.

After having owned many early Colt SP's and having had many more pass through my hands, I've never seen a factory rifle with a three-position selector.

I have seen M16 bolt carriers, and I have seen M16 hammers and disconnectors, but never a selector.

I'd bet money that the selector is an after purchase install.

Here are is the comparison for your reference.
