Burris customers tend to be pretty hardcore. They are the guys who eat, sleep and breathe hunting. Guys who would never let a little thing like pouring rain or sub freezing temperatures put a damper on a hunt. Dawn to dusk hikes in brutal terrain. Hours of glassing. Wet feet. Cold coffee. No problem. They simply come with the territory. To these guys, there's nothing better than fresh tracking snow, a breeze in their face and a burris scope that will put bullets on the money from one zip code to the next. Which is exactly why they choose Burris. We share their passsion. Burris Optics has there, done that. And it shows in every burris riflescope, burris binocular, and burris spotting scope they make. To build a Burris scope, they start with some of the world's best glass, then grind and polish it to exacting tolerances. Burris index match their HiLume multi coating to every lens so each surface transmits 99.5% of the light . That optical excellence makes a huge difference in the critical half light of dawn and dusk. They assemble those lenses in the toughest 6061T6 aluminum outer tubes made. Double spring tension secures the internal tube. All adjustment systems are positive, repeatable, steel-on-steel, with audible clicks. That translates to unfailing shot-to-shot accuracy, no matter how hard you hunt or how heavy a magnum you shoot. Every molecule of moisture is purged from a burris scope by injecting it - 24 times to be exact - with laboratory grade dry nitrogen. Once the moisture is gone, Buris exclusive quad seals make sure it stays gone. For life. Burris Optics manufactures most of their products here in the USA, in their own factory. Burris is a stickler for detail - maybe even a little obsessive. We back most of what we make with a Forever Warranty. Their customers head for the hunting grounds confident that their optics will deliver all the performance they paid for.
