Thank you @thornejc

To anyone who has one in hand, is it a mil spec type quality heavy-duty mount?

How secure and heavy-duty is that LRP mount?

How well does it hold zero?

From the pics it looks like the swing lever could catch and snag on objects, a sling or h-gear and bust open or break from impacts.

Is the LRP mount and bolt screw prone to breaking like their factory low mount?

Do you trust the LRP mount, is it GTG?

All I have to go on, are the factory pics of that mount, and they sort of tell me to not trust and ditch it. So your real world experiences would be appreciated.

I use one and absolutely trust it.  The lever actually does lock into place even though the locking mechanism isn't blatantly obvious like the larue.  I would 100% trust it on a hard use rifle.
