Let's review the issues:
(1) The bolt does not draw back easily.
If the upper receiver is not mounted, I would assume the bolt can be draw back easily (?) Since I don't know your experience with C96. Let's do a small experiment if you have not done it yet:
In assembled mode, hammer cocked, one hand hold the gun and push the muzzle against a solid surface, such as table top. The barrel should go back around quater an inch, and the bolt is unlocked in this mode. Another hand pull the bolt open -- it should be very easy to open the bolt in this mode, because it's unlocked.
If the barrel cannot be pushed back, or the bolt cannot be easily opened when the barrel is in its back position..... probably the bolt lock has some issue. Otherwise, I did not see any problem -- C96's bolt locking machenism is not smooth at all. As long as barrel can be pushed back, and bolt can be easily opened when the barrel is in its back position, I did not see any problem.
To be continued..... hold on
