I read reviews about them and they seemextremely impressive...
I have searched reviews about sightron, and people are saying this is one of the best scopes to buy...
For every reason...Holding zero, eye relief, clarity and brightness and price
And are back with probably the best costumer service in the industry..
The only thing I can't find anything about is weather or not its a one piece tube.(a scope that holds zeroand a 1 piece tubeare the 2 most important things to look for as far as I'm concerned)..
Forgetting the fact that it may leak,there is no point depending ona scope to hold up to recoil (or an accidental fal) when the threads determine the weakest point..
If its threaded too deep there may only be 1/16 of an inch or less of alluminum holding that scope tube/ eyepiece together.....
