1. Yes I watched the video. Followed it step by step. The HBI spring shifts after a few shots, and just will not hold its position.
2. Yes it worked out of the box - but the trigger sucks (knew that going in.) That's why I did step #1 above.
3. I was thankful that the trigger screw was not welded.
4. The fact that CZ still ships Scorpions with the horrible safety is a puzzle to me. I read that it was bad but it was far worse than I expected. The HBI small AK safety is outstanding! Why does this not come on the gun in the first place?
5. Still not sure what mags to buy. I have the 2 factory mags but will need more. (Read all the posts on pros and cons.)
6. Sling mounts will still need modification.
7. Why the pinky sized charging handle?
My firearms experience to date 40+ years. Military (Army Armor) including arms room officer and now civilian instruction and 3 gun competitor. Handled some guns in my time.
I still have hopes for my little Scorpion but much of what I just described could easily be remedied by CZ before they sell to the public.
* NOTE: I have had many discussions over the years with reps from many of the top gun companies. When I asked those who represent guns known to have rough triggers why that is so I get the same immediate answer - "the Lawyers!

They fear lawsuits that may result if they have a finely tuned trigger.
My Sigs have the SRT

, my Colt Competition came w/ a Geissele

Not expecting that at Scorpion price point - but come on.
