SRT Baffle stack with no index

[madkiwi]

So I recently purchased this DLO tube Sterling Mk 5 built by John Andrewski with an SRT suppressor.



Decided to clean 20+ years of crap out of it before using it. Emailed Doug Melton of SRT and he told me how to open it up.



Got it apart and looking much better now.



Now when I put it back together neither the spacer tubes nor the baffles have any indexing guides. When I look online at other suppressor manufacturers' products they seem to line up the baffle notches, frequently with index guides to make it idiot proof.

Doug told me that when I reassemble the suppressor the notches should be rotated 120° from one to the next. John Andrewski said the drag/disturbance by the notches will affect the bullet path if they are in line.

I'm having a problem reconciling that with the way other manufacturers seem to do their baffle stacks- with the notches inline. Has the research proven it doesn't matter?

My question is- Should I do it the way Doug intended (suppressor was made 25 years ago) or just line up the notches like everyone else does it?

Secondary question- synthetic motor oil or synthetic high temp grease for the suppressor threads?

Thanks!
