Scope Rings. Badger rings are machined from the highest quality materials as serialized matched pairs. This guarantees that both rings are identical and eliminates the damaging effects of poor fitting mass produced rings. All ring hardware has been designed by us and is made to our specifications including the TorxÂ® screws that hold the scope securely in the rings. 34 Items Available.
The largest sinus cavities are about an inch across. Others are much smaller. 1  Your cheekbones hold your maxillary sinuses (the largest). 2  The low-center of your forehead is where your frontal sinuses are located. 3  Between your eyes are your ethmoid sinuses.  In bones behind your nose are your sphenoid sinuses.
Sinus headaches and pain occur when the sinuses are swollen and their openings into the nasal passages are obstructed, stopping normal drainage and causing pressure to build up. Often the pain is localized over the affected sinus, perhaps causing facial pain rather than a headache.
