I agree DR was ok but not my favorite country, the food was lacking. The majority of the locals were friendly, more than could be said for some areas in our own country.
My defenders are older and the ocular rubber has stretched. Both caps d0 the job of keeping dust and dirt out but on more than one occasion I have completely pulled off and semi threw the cap on the ground. Which tends to screw up your concentration on the task at hand.
I use the BallisticsARC app. You can try it for one rifle for free and it works well with my iPhone. It also can be used with weather flow meter or kestrel meter or get info off your closest public weather station.
