Ave quality, poor instructions, virtually no clearance.  Consumers have gotten used to the idea that an average product is somehow excellent.  There is nothing particularly strong about this product.  It meets my minimum expectation overall.  The clearance with a 40mm nikon rimfire scope on a ruger 10-22 takedown is almost zero.  It almost touches the barrell.  This is a terrible oversight.  The lens/dust cap will not fit (it is that close) so I have to cut and modify the lens protectors to get them on.  The instructions do not give guidance on recommended positioning of the scope, centering (or front or rear justified).  I did not buy and install a series of competitive products to see if and what might be better.  I can say that this product in its design and implementation falls short of what you should expect.
