Generally, Burris scopes have good quality and durability. That said, the lower-priced product lines tend to have lesser-quality glass and a less robust build than higher-priced product lines. That stands to reason. Also, the more electronics inside a scope, the less durable they are, simply because recoil, moisture, and field abuse are hard on electronics. That’s why Burris’s celebrated Eliminator line of rangefinding rifle scopes tends to have weaker warranties than non-electronic scopes. But Burris’s XTR Pro series of tactical scopes are among the best and most durable precision scopes on the market.
