He still hasent posted pics , more than lkely it is not a US military used one, probably just a civilian one made by universal
Generally, the Universals are considered t be junk.
However, there are some made with military surplus parts that are ok.
The ones with the stamped op-rod are the crappy ones.
If the one he's selling has a military op-rod, it's probably a good one.
Get it for $300 or less.
If it has a stamped op-rod, avoid it altogether.
