The R-Series mounts to any weapon system with picatinny rails and includes built-in lens covers. Sadly, these will not be available in most countries due to ITAR restrictions. Only 9hz refresh rate thermal sights are exportable without State Department approvals. 
The affordable (only $3,500!) 1x sight has some limited options (no fancy reticles), but I can see it being excellent for hog or varmint hunting 50 meters and in. FLIR additional pictures, videos, and details on their R-Series website.
