The Doctor Optic comes with metric screws and the mount uses standard threads. The mount came with the right screws, but I did not realize it and tried using the metrics which stripped the the threads in the base.
HOWEVER, I sent a message on MattBurkett.com and got a response within one hour, in the evening, on a Friday! Matt set me straight and promised to have a new mount out in the mail the next day! Amazing customer service!
The mount is very well made and sturdy. It fits easily on my AR and puts the Doctor Optic in a great position for fast target aquisition.
If there were directions stating the issue with using the screws that came with the Doctor, I might not have made the mistake (but you have been forewarned, so no issues!), however, Matt set things straight faster than I could have ever hoped.
I DEFINITELY recommend this mount to anyone!
Pros: Sturdy construction, flawless function, complete package
Cons: No Set Up Directions
