New Hatsan Bullboss questions

I have been wanting a PCP gun for a while, and couldn't pass up a new Bullboss in 0.25 on sale for only $329+tax. Not having an air source, ammo, or anything else yet, I removed the stock to clean it. While I didn't expect a refined rifle for the price, I noticed a few things that I have some concerns about

  1. Looks like there is a missing e-clip in the trigger group?? Based on some reading, others have had this issue.
  2. First few threads of the rear action screw are pretty much done. Is this normal for this gun? There is plenty of engagement of the other threads. Maybe they used a plug tap instead of a bottoming tap in the received hex nut...
  3. Similar problem with the one front cocking lever screw. This one just looks overtighened.
  4. The magazine that shipped in the gun appears to have some machining issues.

    A few pictures below. Have people seen these problems before? Looks like I am going need to need some parts from Hatsan or return this rifle.

    Still on the way:
    74cuft Air Venturi tank
    Vortex Diamondback Tactical, 30mm, 4-16x44 FFP.
    Ammo
