    Scott and the others thank you so much for the replies. So you think it's GTG saying I have a all Colt rifle? I sure appreciate all the help and I have learned a lot as well. I wish I knew who made the carrier and bolt that was in the gun. They appear to be of high quality and properly staked gas key screws and very few rounds, as I said the barrel has had less than 50 rounds through it. I plan on changing that this weekend, lol!! But the Bolt and Carrier have no markings on them at all. From what I hear Colt has always marked their carriers and bolts, right? That one is a spare and I purchased a FA BCG made by Colt and properly marked. Thanks to everyone again!!

    That buffer is rifle length, and isn't going to have an H on it. Also not too many companies used notched hammers, and Colt does. Those trigger pins just from my naked eye also look like the over sized pins Colt used to use, and would be tough to find another commercial FCG using that size pins.



    Can you post a picture of the "tail" on the trigger? That's the rear area where it contacts the selector.
    a bushy i bought from a friend has a notched hammer. in your opinion what hammer is better notched or non?

    I just checked the hammer on my 6700 CH. It's notched like the OP pictured but mine has an S on the right side. I know it's factory, I bought the rifle new in the early 90's.

    I bought a MT6400 Lower for my build and it has a "M" stamped on the Hammer not sure of the year of my Receiver ,But it does have the .170 FCG pins, But I am Cool with it.it works.I have a double star Lower that a Dealer Built , Put Colt LPK in and it is .155 I have to say I have never seen a Buffer like that

    This unique buffer was something Colt used for a couple short years on their civi rifles. I see no reason to change it as it works just fine.

    The trigger does look like what Colt uses. There are tons of parts out there but most of them are square cut in back "tail" where the trigger makes contact with the selector. If you look on yours there its not cut square in the back. AFAIK only Colt does this. On an M16 FCG the "tail" is not square cut, and is not solid across the back like an AR15 FCG. Colt removes one of the "ears" that would make contact, and turns an M16 trigger into an AR trigger.



    They have had some oddities in parts over the years like that plastic rifle rifle buffer. I bought a similar gun (first AR), and it came with an M16 auto selector. Ive since discarded that selector, and installed an AR15 selector. It used to not be uncommon for companies to interchange parts between M16, and AR15 versions as long as it didn't make the gun FA. Its a lot easier to stock one type of part. Now its a big no-no to have M16 parts even if the gun doesn't fire FA (BCG's are ok).



    Here is your pic to show what Im talking about:





    Look at this graphic, and the difference between an M16 trigger and AR trigger. The AR is solid across the back. M16 is open. As I said Colt takes off one side to make an AR trigger.







    My Colt hammer and FCG:







    Here is a CMT/Stag AR15 trigger...note the close off square cut back:

    On an AR15 I don't think it makes any difference. Ive used both quite a bit, and cannot tell any difference.

    The trigger shown is a Colt .170 trigger appropriate for what you have. All .170 components for are semi-auto use.
