Let's talk about some interesting stories.
Although it is hard to say what the 5.56 version of the Type 88 sniper rifle sold to southeast asian countries in the early years was called, the actual model of the "Type 97 sniper rifle" sold to the Canadian civilian market was not "QBU97", but "NQU03". The reason why it was specially renamed "Type 97", was deliberately made to form the relationship with the type 97 rifle. The lab was deceived by this, and really thought it was a sub-model of the 97, so the first batch was put on sale without much inspection.
After the sale, they realized that something was "wrong" (the 88 sniper is actually based on the SVD, and the ridiculous regulations prohibit the sale of SVD and its derivative models). At this time, dozens of them had been sold. Some said that more than 30 were sold, and many others are still in the dealer's warehouse and cannot be sold). This is why the emergency stop was made.
In 2014, domestic exporters planned to repeat the same trick and renamed the type 97 rifle to NQZ03, intending to make the type 03 rifle family to get through again (however, they did not even change the receiver inscription this time), but the lab would not fall for the trick a second time.
By the way, the plastic parts of the NQU03 exported to Canada did come from an early batch of 88 sniper rifles that were scrapped due to improper storage. This is why the plastic parts and receiver S/N on some guns are not matching.
