Very nice work.
That would be very secure, actually the most secure I've ever seen for an SVT.
It does share one problem with the rest of them though.
You have to remove it to clean the rifle and the rifle needs to be cleaned every time it's shot.
That is far more urgent if using Russian surplus ammo, most of which is horribly corrosive.
If the mount is really snug on the grooves, which I suspect it is, who knows, it might repeat zero when reinstalled, in which case, no problemos.
The rifle did need to be permanently altered in this installation, which is unfortunate, but you have indeed found a way to get the mount to stay still, which is near impossible using any other method I've seen.
