I can take it apart its putting it back together.
It's not hard, you just have to know the right technique.
1. Push the locking piece and firing pin into the bolt head, and turn 180 degrees clockwise.
2. Put the bolt head onto the locking piece with the grooves in the bottom facing the left side of the carrier as it is installed in the rifle.
3. Turn the bolt head slightly so the carrier locking lever is aligned with the upper groove (since it's turned on its side) of the bolt head.
4. Push the bolt head back into the carrier, and push down on the back of the locking lever. It will ride up into the groove on the bolt head. (See pic below). You want it so it is just up on the rear of the carrier.
5. Push or pull the bolt head in or out so the locking lever is next to the ramped surface on the very rear of the bolt head. There is also a rim on the rear of the bolt head, it should be just inside the lip on the carrier.
6. Turn the bolt head clockwise until the grooves are facing down, then pull the head forward until it stops against the carrier.
7. Done.
Try it a few times, I can do it in 10 seconds, even with oily hands during cleaning. It just takes a bit of practice, and not brute force or any special tools.
Here's what step 3 should look like:
