Does anyone have a center support they can measure and provide the specs on (length, ID, OD, Wall thickness, etc).

TIA,

Are you talking about the ones that TAPCO sells. If so, I've got one at home I can measure for you.
Yeah, that should do. I've got a bunch of steel rod laying around and wanted to make one, but need to double check the measurements. I appreciate it!

I have a couple of hungarian center supports, and I'll get one out in a bit and get the measurements for you.

Here are the dismensions for a TAPCO center support bushing.

Over all length: 1.175''
Outside diameter: .200''
Inside diameter: .160''
Thickness: .040''

Originally I tried to use one of 1-PAT's group buy long rivets and it wouldn't fit through the hole. Then I tried one of the TAPCO long rivets and fit just perfect. Tapco long rivet diameter: .150'' 1-Pat's long rivet diameter: .175''.

Hope this helps!

The hungarian center support (the one global trades sells) has these measurements:

Length: 1.179"
ID: 0.158"
OD: 0.275" on the outside edge and the center OD is 0.243"
wall thickness: 0.062"

the rivet that comes with the center support is 0.156" thick and the overall length is 1.626"
Here is a picture of it from globals website.


edit: and the actual center support and rivet aren't a green color like in the picture, but a silver colored rivet and the center support looks like a blued/black color.

This is exactly what I needed! Thanks everyone!
How can there be such a difference in OAL? Lets say you use Tapco rails with both of these center supports. One is goint to be off by .015''? Is this an acceptable tolerance?

Speaking of center support sleeves; has anyone tapped one of these for a total screw built AK? I have one from Tapco and I plan on building my AMD 65 totally with screws.

Unless I am missing something - wouldn't the difference in OAL only be .004"? (1.179 - 1.175 = .004). I could find .004 to be a more acceptable tolerance than .015.

Yes, 7.62x39 has rifle drilled some rod and tapped it for screws. I would imagine a person could use 1/4 or .25 rod from Home Depot and do the same. This is exactly what I plan on doing.
