An actual Ops Core mount is 80 to 90 dollars which is ridiculous for a piece of metal.
That is, until you buy this one. I compared this one to an original that a co worker has and it looks like the real one with some production flaws. Paint chips, mold flash, the color was off a bit, nothing major.
Nothing major until I needed to use it. The rhino arm fits perfectly into the original ops core unit.
It was very tight on this one to the point that it cracked the mount and rendered it useless much to the amusement of my co workers. Bottom line is, if you need to actually use this, don't cut costs and get the real one but if you just want it for looks, this is fine.
