Of the Olympics I have worked on some had gas tubes crimped, one had a ball bearing jammed in the gas port and another had something rammed and glued (I think) in the gas block.

Also standard 1:12" M16 barrels were used on the Cam rifles, complete with gas port.

There are no S5 parts, only parts of S5 firearms (from the HO).
Apparently, when broken down, S5 weapons' parts can become S1 parts in certain circumstances.

We would therefore advise that if you were to manufacture a firearm using a similar process that you seek your own expert technical and legal advice at your own cost. Ultimately, it is for the courts to determine whether the weapon manufactured falls within or outside of section 5 of the Firearms Act 1968 (as amended).

BUT if they were made from parts from taken down Sec 5 firearms then they were NOT OK. I was told that you had to have some pretty good evidence that you were using fresh unassembelled / newly made parts to get Sec 1 status for the finished article. It will be interesting to see 1) If we ever find out the true story behind this and 2) If the Home Office clarify A) The rules and B) Who issues the 'Approval'.
