Opinions: ACE stock on 858 Carbine?

[QUOTE
What material is the rear end of the ACE stock made from ? Some kind of polymer, or aluminum? I believe the top limb is Delrin.[/QUOTE]

The front and rear are 6061 aluminum with aluminum tubing connecting them.
The top tube has a poly overtube to keep the aluminum tube from feeling to hot or cold on the cheek,

Well, aluminum is a decent material to work with. I can't import an ACE, and at present I know of no Canadian supplier, so perhaps it's time to get creative.
