Can someone tell me the outside diameter of the receiver extension?

Thanks in advance.

Not sure what you are looking for so try this link. Maybe it will answer your questions. Print it out, it is good info. [url]http://www.ar15.com/content/docs/lowerBlueprint.pdf[/url]

Thanks, TAC40, but the extension is not in the blueprint.

Sorry that didn't help, but I did find out it is threaded to 1 3/16" x 16tpi. If you are wondering about length there are 3 different sizes out there that I know of. The shortest is for the M-4 style collapsible stock, the A2 stock version which is the longest, and the A1 version which is slightly shorter than the A2. However, I don't know the dimensions.

OK, could someone who owns a caliper PLEASE measure the outside diameter of the lower receiver extension (buffer tube) and give me a reasonably accurate measurement? Thanks.

I got 1.120" on the LE tube I had laying around.

Are you wanting the diameter of the rifle tube, a Colt collapsible stock tube, or a commercial collapsible stock tube? They are all slightly different.
