yup - just roll over it on the opposite side, fix it in the field for battle : truck or even tractor works best
These rifles are very crude with robust factory tolerances. The T81 isn’t pretty and your rifle is likely fairly typical.
They are collectible for military rifle enthusiasts.
I had a Stag AR15 that I had to drift the rear sight all the way to the right to zero. I was told that it was within factory tolerances even tho I could see the front sight was slightly canted. So, it happens sometimes when tolerances stack up.
If it zeros, and it groups well without falfunctuons, you’ve got yourself an example of a PLA T81.
I would buy one of these rifles if they ever come down to 1/2 the price they are asking.
