[ARCHIVED THREAD] - How can I identify what manu of upper I have?

Posted: 9/7/2004 12:05:32 PM EDT

I bought a AR when I was 16 or 17 yrs old, which is almost 10 yrs ago now. Well I bought it from another individual used, the lower is DPMS but there are no marking on the upper except for a DK on the carry handle. Anyone have any idea who made this?

There's no way of really knowing unless there are any stamp markings on the barrel in front of the fr. sight housing? And, are there any stamp markings on the carrier or bolt assy.?

Generally speaking, aftermarket uppers only show a forge marking, and everyone is using the same forges. Only Colt and Diemaco in Canada have consistently put a makers mark along with the forge mark.

HOWEVER--early Bushmaster production also had ID marks that showed who made the piece---and that's what you have.

The forging is a Kaiser, and the upper was built by Bushie

The "DK" uppers have been around for awhile, and nobody has been sure of the brand. I've had two of them, sold one, CMMG had one on the EE about a year ago, as well as one or two others. Its a Kaiser forging, but NOT a Diemaco. Both of the uppers I've had came with non-chromelined barrels and the FSB's were held on with roll pins.

Don't know about the rollpinned FSBs, but I have a pre govt contract Bushie barrel that is totally unmarked, and unlined.

Bushie didn't start lining and marking their barrels unril they got that contract.* Til then they were just another aftermarket AR peddler. As far as the DK upper marking goes, that info is off the Bigger Hammer wabsite. Now I don't put much faith in anything on that site any later than about 1990. but for the early stuff Bigger Hammer is pretty complete and accurate.

*And they got that contract because Bushy's President is a big Republican honcho in Maine---and how far from Windham, Maine is the Bush summer home?

What "contract" would that be shamayim?

Diemaco uses a very stylized angular "D", there is a picture of it in the FAQ.

???????What are you talking about? My comments are referring to BUSHMASTER. Where did you get to Diemaco?

The DK marking has nothing to do with Diemaco. According to Bigger Hammer (and in this case I believe it) it's an early Bushy code marking; and the contract I referred to was BUSHIE'S gov't contract of about 15 years ago.

Not everything I write is in reference to you shamayim. Others were talking about the "D" on the uppers.

Now, tell me more about this Bushmaster "government contract".

You've peaked my interest also.

Please, you've got to be pulling my leg

I refuse to believe you two are unaware that Bushie built several thousand M4s in 1989 or 90, "on government contract".

(Edited to Add) On another thread, Troy says it was 3500 M4s. Then Colt -653 came in and said Troy had the number wrong; it was only 350. Have no idea which figure is correct. But I've got to believe you guys knew it. It's mentioned too many times on this site, and you guys are too active on the site, for this to be news to y'all.
