With most of our optics being made of high strength aircraft grade 6061-T6 aluminum, multi coated glass, and featuring our smart spherical structure design, they also undergo some of the most stringent modern day testing available, including but not limited to 100% waterproof testing, climate testing, and shockproof testing. While all of this comes together to create some of the most durable and reliable optics on the market, we still understand the extreme abuse our gear can take, whether on the battlefield or in the mountains. At Farris Optics customer satisfaction is among our core values. We want to make sure each and every customer that supports us with your business is satisfied to the best of our ability in return. That is why among offering our customers a 10 day return period on all product, we offer our customers a 3 year unlimited product replacement warranty! This includes all performance impacting issues.
