One of the advantages of the MK II is the fact that no tools are needed for disassembly and reassembly. Moreover, it's really not that complicated when you've done it a few times. Use a paper clip or empty .22 brass to pull down the handgrip lever to get it started, ,ake sure you are aware when the hammer has to be forward or back, and it's simple. My son's Buckmark requires an Allen wrench to disassemble, and to me the MK II is much more user-friendly.
