Hi folks. First post. Coming at ya from Pittsburgh, PA. I was directed here by a member of the 1911addicts forum.
I was given this rifle yesterday... http://i1077.photobucket.com/albums/w473/melter942/AR%2015s/Colt%20Sporter%20II/DSC08932_zps2cff627b.jpg http://i1077.photobucket.com/albums/w473/melter942/AR%2015s/Colt%20Sporter%20II/DSC08934_zps7133ca82.jpg http://i1077.photobucket.com/albums/w473/melter942/AR%2015s/Colt%20Sporter%20II/DSC08927_zps421c70d3.jpg The serial number dates it to 1974 manufacture. I was thinking it may be an A2 lower wearing an A1 upper, but that's not the case. In googling for info, I found another thread on this site with an identical rifle, also of 1974 vintage. It has an M16 BCG and I'd like to replace it with a vintage Sporter II carrier. Here's the "C" marked BCG that's in it now: http://i1077.photobucket.com/albums/w473/melter942/AR%2015s/Colt%20Sporter%20II/DSC08939_zps69e9f428.jpg My goal would be to get this rifle back to it's original configuration and enjoy it for waht it is. I think all I need is the complete FCG (I installed the factory parts from my 6920) and the BCG. I'm not sure if the hammer/ trigger/ disconnector has changed since 1974, but I'm pretty certain the bolt carrier is not correct. Any info or insight is certainly welcome and appreciated. Thanks for your help... Joe |

It's the 6400 model from Colt and many people would consider the BCG you have in it an "upgrade" over the one that came in it as it was not modified like the original one was. The original one works fine but I wouldn't be concerned about putting back in the correct one.
Welcome to the forum! |

Quoted:
The Sporter II line was mid 80s. The 1974 serial range for SP1s are 5 digits SP32601, yours is a 6 digit. Bolt carrier you are looking for is the shortened rail w/ exposed firing pin channel. Fire control group should be C marked and a notched hammer. Quoted:

I thought it came with the shortened carrier. Not crazy about the exposed FP channel, forgot about that detail. The FCG I put in it is C marked with notched hammer, good enough for the time being.

A couple questions and a couple quick answers and you guys are setting my thinkin' straight. I might keep my eyes open for vintage parts but leave it as is for shooting pleasure. Thanks for the welcome... with the knowledge base already here, not much I can add, except maybe some pics now and then.

Where at in Pittsburgh in relation to Mineo's? 
Often you can get people to swap a half moon Colt carrier for an M16 carrier, such as you have. I'd keep the one you have now, but if you really want to go back to stock a WTT advertisement in the EE will likely get you there. |

Do I want the half moon or the shortened carrier? Not really looking to trade, hoping to buy the right one and have both. |

Was thinking of the later rifles. Sorry about that. |
| Did the later Sporter II's have gray A2 uppers? I had one roughly 10 years ago with an A2 upper and big head FA, I don't remember the serial number but it was late 80's production came in a blue box. Traded it for a FAL to my uncle, we both still have our trade rifles. |

OP, you may be in for more trouble than you can even imagine.
I started a few weeks ago with a trade for a Colt SP1. Then I decided to by a Colt M16-A1 rifle kit and built a late Vietnam era clone. Then I bought another kit (you never know how long they will be available, right?) Now I am building a XM177-E2 clone. If I wasn't broke, I'd buy another kit. It's a very, very slippery slope. |

Got my first one, an SA TRP on July 1, 2011. Here's what's in the safe today: Two more USGI pistols incoming this week or next. |
