First of all AR 15's are a new hobby for me even though I have been around guns all my life so please excuse any errors as I may not know what I am talking about completely. I have a Colt Sporter Competition H-bar that my wife bought me as a gift from a friend of mine. It came with a 16'' M4 profile barrell and a RRA six position stock. The gun is in great shape but I found this configuration odd, so I did some research on the web. I found that the gun did not originally come that way. The rifle has a CH serial number prefix and is a model number 6700 according to what I found at biggerhammer.com. According to that research it says this gun is a preban 92' era gun that should have a 20'' H-bar barrell with not bayo lug and an A2 flash hider. It is also supposed to be an A3 removable carry handle type, which it is and the upper does appear to be Colt as it is stamped. The upper and lower match color wise and they have a very snug fit together. It is also supposed to have a fixed stock with a raised cheek piece. I asked my friend about this and he said yes I was right, and he gave me what he says is the original parts. A 20'' H-bar barrel, A2 flash hider, no bayo lug, gas tube, handguards, and the stock with the cheek piece. All these parts seem to be in great condition and I can only find one mark on the lower where it looks like it might have gotten bumped in his gun safe. The barrell is stamped C MP 5.56 NATO H-bar and the stock cheek piece has colt on it. My wife was being a great wife for christmas and bought this for me after getting with another friend of mine I work with. He hooked her up with the guy she bought the gun from. She new I was wanting an AR so she took it upon herself to find one and I hope my buddy did not take advantage of her. I don't think he would as we are both in the same line of work. I want to put this gun back original and then assemble a RRA. Can anyone help me find someone who is experienced to dissassemble this gun and reassemble it the way it came.

Any help for this newbie would be greatly appreciated.

If you're in the Atlanta area, I would gladly help you reconfigure your rifle.

I will pay a gunsmith or armorer to put the gun back original I was just trying to get some insight on who to take it to. I would really like to be able to watch them take it apart and put it back together if possible. Aside from cleaning the ones at work I have never taken one apart.

What is the normal fee? Is the headspacing thing involved with this particular request or is it a non issue. Does the bolt group have to be changed due to barrell length, I just thought of that, or is the bolt group the same no matter what the length of the barrell.

I'm hoping to use the left over barrel and stock for another build. My buddy says the 16'' barrell on the gun now, is a RRA piece, how do I tell. There are no markings on it like the colt. Are they under the handguards?

Thanks again.

I would by my own tools as I would use them later. Is the best place to by them brownells? There is a Delta ring on the gun now and I hope it is the colt one that came on the gun, if not is it hard to find another one. Does it matter? Can you tell.

I'll bring the gun any where in the Atl. area if someone is nice enough to help, probably just have to find a day to do it.

Oh and what about the headspace thing? and how do I tell if it is a RRA barrel?

Hey welcome to the board, you are in the right place. We need to make sure you rifle is up and running for the group shoot next month. You are invited!
Link Posted: 2/26/2006 6:30:04 AM EDT
Thanks, I'd love to if my schedule permits. I might have to wait a little while on the tools because I just ordered a RRA tactical entry two weeks ago. I kind of have to give the wife a cooling off period before I spend too much more money. I ordered it before I realized this kind of info. was available. I'm gonna keep it for work and use the Colt at home and hopefully build another RRA from the pieces.

Does anyone know how to check this barrell to see if it is a RRA piece.

I don't see any. I've heard they may be under the handguards? Unless I am looking in the wrong place. They are not in the same place as the Colt.

Now I am nervous, after reading stuff on here about bolt carriers. My buddy said he changed it over cause he wanted an m4 clone. I don't no for sure if he fired it in this configuration. It don't look like it. Is it going to matter if when I put the original barrel back on that I use the bolt carrier thats in the gun now. I would have to guess its a colt and that it would work right?. And if I use the m4 profile barrell later on another build I'll just have to make sure I buy a new Bolt and carrier, right?

Thanks, I know too many questions!

I am in Douglasville and have most of the tools to rebuild the Colt. (Do so at many gunshows for dealers and friends). Let me know if I can be of service.

Does the configuration of this gun sound correct to anyone and what is this I'm hearing about the colts with a cheekpiece on the stock as being a "delta". What is that and is my gun one. Is anybody out there a colt specialist. I've tried biggerhammer.net but my computer won't pull it up and I called colt today only for the lady to say, "all i can tell you is that it was made in 1993" someone help! please.

The Delta was:
- the R6600DH made from 1987 to 1990 - probably large front pin and slab side, bayonet lug with aluminum case serial numbered to the rifle, special Detla logo'd pistol grip
- the R6601DH made in 1992 - no lug could be either slabside or A2 lower. Both came with a 3x scope and cheekpiece.

Then there was a R6700CH Sporter Competition HBar select with a removable carry handle, 3x scope and cheekpiece made in 1992 - no lug

You probably have a standard Sproter Competition HBar, either a slabside 6600 with a bayonet lug on the 20" barrel or a 6700 without a lug. I cannot say unless I see it.
I plan to go to the Carrolton gun show this Saturday - give me a call and let's meet to check it out. I can probably swap the barrel out in the parking lot for you.

I sent you an email also but I was checking the board. I plan on going to the show as well. I'll probably drop by while I am at work on saturday but then come back to really brouse on sunday. I've found that I do not have a colt bolt and carrier group in the gun and I am trying to get with my buddy to see if he still has it. Evidently he put on a new RRA barrell and bolt when he did the swap. I still may bring it if I don't get in touch with him cause if he still has the bolt I can put that much in later. I just can't put the barrell back on.

Thanks for all your help I will try and give you a call tommorrow.
