SKS receiver cover w/rail=garbage

[jt_trouble]

if you did YOUR research [and thread reading] you would have realized ....

That receiver covers are not ideal for mounting a scope onto a SKS. There are probably 50 threads in the Red Rifles section with complaint about these types of covers.

Marstar doesn't brand any of the products they sell, just the photos of them. If the part numbers start with "LP" it's a Leapers, if it starts "NcS" its made by NCStar ... and with NCStar. You get what you pay for.

Goozyman, ditch the dremel and get a real grinder. A good bosch 1/4" with a real burr will make quick work of any offending steel in your bolt's way. Sounds like you havent ground enough material away yet. Your cover just needs more work. If man made it (especially out of steel) man can mod it.
