Stripped lugs on install - Warne Rifle Scope 34mm Permanently Attached High Rings

I ordered these rings to mount my Burris optic to my Tikka T3x TAC A1 chambered in 308. I took it to my local gunsmith to mount and the lugs to tighten the mounts stripped during the installation. Although he was able to mount the scope, I’m hesitant on how durable it will be once I take it out and shoot. I would not recommend this product simple based on the problem of mounting it doesn’t give me much comfort moving forward since if I ever have to remove or adjust I’ll have deal with stripped screws.
