what parts would go in a mechanical ULE mag?

[Aegis]

Are there ULE parts besides the body available? I intend to start buying parts to make the lightest mechanical mag possible.

THinking ULE body, xvalve, intelliframe - is there a ULE rail, or a lighter version of the intelliframe?

There is the ULE trigger which is an on/off that makes the pull about 15 oz. but only works with the x valve and retro valve. The stock mag trigger pull is 3 pounds so it is a big difference.
