I looked at this Colt Sporter Target (It doesn't say H-BAR). The serial number prefix is ST. I can buy this for $699.00. Is it worth it? I popped it open and saw this: What is the "Colt Block and the red thing for?  Do these pins look normal?  Here is the other side:  Here is the barrel. What does the CMP stand for?  |

CMP + Chrome lined and magnetic particle inspected/checked
Looks like the large FCG pins to me .0171"? The Colt block is to keep you from using a FA bolt I bought one of those not long ago. I just couldn't get past the block and large pins  Yes, if it is original and not beat, it is decent deal at that price.
ETA: The red thing is an accuwedge. It makes the upper to lower fit seem less sloppy. |

Based on your pictures, if I saw it in the store for $699.00 it wouldn't be in the store anymore. It would be in my safe next to my SP1. But, I like old Colts.
Except for the Accuwedge, it appears all original. Although some of the parts are different than normal, like the large FCG pins and the block, it was normal and original to that Colt model. |

If I saw it for $699 it would be at my house by now.
It's looks like it's a complete Colt R6551. Other questions have been answered adequately. Pull the "red thing" out, Accu-wedge is nothing but snake-oil, IMHO. Don't worry about the sear block as long as you're using the factory bolt carrier, no need to replace it with an FA unit, especially in a rifle. Cutting it out is only necessary if you do a lot of upper swapping. Honestly, though, I'd just keep it box stock and shoot it and have loads of fun with it. ~Augee |
| The last decent $700 older Colt AR walked out of the show with me. I "worked" the owner 1/2 dozen times walking around the show until he finally agreed to sell it. [His wife was being a PITA in the dealing] I'd pick that one up for that price pretty quick. I don't like the block and not all of them had it around that era but it won't hurt anything either function wise as long as you use the original carrier. |

Quoted:
so wait with that big block in there you couldnt use like a NiB m16 bcg? You are correct-you cannot use an M16 carrier but you can use a full circle AR carrier: 
ETA: The factory carrier that came with Colts from that era is open all the way back on the bottom. It's known colloquially as the half-moon carrier

BUY IT. $699 for a Colt is a great price. Defintely. Has the mil-sepc diameter pivot pin too, and the sear block appears to be the single small pin variety, which is the best if you plan to remove the block. I wonder if the PP is drilled for the spring and detent. That is a added Colt plus to have, |

I think SAW offers this service. |

On the blocks with the small diameter pin (like the one in the pics on the first page), the pins are press fit into the wall of the lower, so you should cut off and leave the end of the pin in place and it will stay there just fine.
The larger diameter pins are tapered and will fall out when you cut the block out, so you've got to glue the pin head in, but I've heard it doesn't work well. |

That is a preban Colt 6551. I bought a post ban version for 700 used recently. It's a great rifle. Quite accurate from the bench with good ammo. Bascially, that rifle there is about the closest thing money can buy to an M16A2. It will have a government profile/A2 profile 20'' barrel. It is NOT an hbar. My dad owns a preban Colt 6601, and I can tell you this rifle handles a lot better than the 20'' hbar. Not awkward at all. It handles like a 16'' hbar. I'd get it. If you want a simple A2 rifle for carrying around outdoors, nothing beats it. ETA: Here are pics of mine. Be sure to check for excessive wear. Being that's a preban, at that price it doesn't really matter.    |

I wouldn't buy that thing. You would have a fixed carry handle (No flat top upper receiver), sear block, oversized FCG pins, a flat head screw for a front pivot pin, no bayonet lug (if you care about bayonet lugs) ..... all for what? Just because it's a Colt?
I would rather have a complete BCM for that price. That particular Colt is about as neutered as an AR can get. If you want a Colt, get a current version. I think this year (2010) they finally stopped the over sized FCG pins. This BCM pictured below will cost you about the same price as that Colt, but you will have every feature any mil spec AR should have. In my opinion the Colt you have pictured above is just a bad reminder of what happens when too many Demorcats are in office.

Being I'm in college, I could very easily go broke and need to sell. Locally, colts are ridiculously expensive, and that works in my advantage if, God forbid, I need to sell. 2) I'm not a huge fan of bayonet charges. 3) It's a good, solid rifle. Not that BCM isn't, but there's nothing wrong with that Colt. 4) There are those of us, though few and far between on AR15.com, who actually use iron sights. I have no need for a flat top. And since 20'' A2 rifles are not "cool" on arfcom, they can be purchased used at very low prices across all the brands. ETA: The rifle you referenced above is priced on the BCM site at $1,135. |
