Burris FastFire II review
The Packing Rat has reviewed the Burris FastFire II red dot sight ...
The RD is small and light weight – it’s likely you wouldn’t notice the difference on Ruger Mark III 22/45. According to the project description, Burris states that the unit is waterproof. The manual instead states, “Although not completely waterproof, the FastFire is water-resistant and is usable even when exposed to moisture.”
water resistant means it might work in the rain
waterproof means the you can swim ashore and the site will sill work
big difference
Cool Like to get one for a doctor sight on my ACOG.
Waterproof and water resistant are two VERY different things.
