The Burris Droptine is made of high quality, precision-ground glass is multi-coated to offer superb low-light capability with glare resistance. A simple, rugged reticle has holdovers for snap shots at extended ranges. The low-profile turrets are finger-adjustable and a separate eye piece and power ring allow for flip-up lens caps. Precision internal assemblies are double-spring tensioned for shockproofing, allowing Droptine to survive a lifetime of harsh field use..
