Nordic AR22 owners - Quick question

Since we are on the subject...
1) How sturdy is the kit? As in, how does it hold together?
2) Does the top part screw onto the bottom part?

Looks pretty nice...

1. The pieces feel solid together.
2. The top portion screws into the top of the receiver/action and is held in place by the front/handguard.
