Howdy All,

I am considering a pair of LE marked Colt rifles that have been offered to me.  One is a A2 style upper, thin 1 in 7" twist barreled rifle (I guess it is a 6520).  The other is a 6920, but I suspect it is an older version.

All parts that I can detect are Colt, but there is a question about the rear stocks.  They are not "M4" style.  They both have CAR stocks instead.  Is this correct?  Anyone have any idea when the "M4" style was used on LE rifles?

Thanks,
Cheese

I did some research.  I guess the "CAR" stock came in several configurations.  These are four position stocks, so I suppose they are original.  

I wonder if an M4 6 position "rear half" would fit on the milspec tube 4 position tube?

While I am talking to myself I might as well ask why I am still sitting here and not buying the damn things?

This is rather nice.  I should come in here to be alone with my thoughts more often.

 Two posts within two hours is a little short on the Colt board. . . .

The 6-position stock probably isn't milspec and it isn't "M4".  The improved ("M4") stocks that I've seen on real M4s are 4-position and the ones on my 6920 and 6933 are 4-position.  I think the improved carbine stock was adopted five years ago or so, but I am sure someone with better information will come along shortly.

What are the markings on the receiver?  Is it LE/Mil marked?  Did you look at the barrels of the rifles to get the "born-on" dates?  Also, you could check with Colt on production dates.

That is funny, cheese

The enhanced M4 stock came along in 2002, I believe ("paging Mr Ryan....Mr Ryan")

The Stag (see CMT, LMT, or Noveske) has the proper buffer tube that can be used.

Colt's is a 4 position, the Noveske is a 6 pos. and I believe someone has a 5 pos.

Remember- it is the buffer tube that determines the # of positions, not the stock itself.

The CAR stock is decidedly smaller than the M4, and the aftermarket models like the LMT/Crane-style larger then the newer M4. Photos abound around here (like in Matt-B's collapsible stock thread )


PS: You were never alone here, we just wanted to watch you on the Colt CCTV a while

My newer 6920 is a 4 position stock.

Redfisher is right and I mis-typed.  It is the buffer tube that determines position numbers.  Colt uses a milspec buffer tube.  Not all tubes and stocks are milspec and you can't put an out-of-spec stock on a milspec tube. . . .

Awesome fellas!

I will be picking the rifles up tomorrow.

I will check the "born on" dates.  I didn't remember that detail.

The rifles are LE/Military marked.  I am getting them for a "get both" price.  I have never regretted purchasing a Colt.  

Unfortunately my wife didn't blink an eye when I told her of my "decision".

That bodes ill for me.  Looks like that brick patio she wanted will be going in.  The one that surrounds the HS Precision Hot Tub..at least the Glock gardens came out nice.

Thanks again,
Cheese

All Colts made after 1994 would have 4 position stocks.  Colt does not make a 6 position stock tube.

In 2002, the switch was made to the waffle style stock.  So if you have a 6920 or 6520 made before that time, it would have the old style plastic stock.

Pre 2002.  That helps.

I do appreciate it.  You are all one dedicated bunch!

Thanks,

check where the buffer tube threads into the reciever, Colt stakes them in place, if the little "divots" are there then it is an original Colt stock tube, you could easily change to the newer style if you wish.

The 6921 is the SBR and you would be making a wise choice.

yes, These will be my first NFA items. The only thing i fear is after purchasing them i may not want to shoot them so they will hold there value being consective numberd guns...plus it will take me near 4 months to pay them off.. 8-9 months if you throw in the wifes stuff I think it will be worth it though.

I love my 6920...
