Very nice red dot sight, I have a Trigicon, aim point, eotech doctor and now the DeltaPoint.. Each has their own advantages and uses for their specific weapon. The DeltPoint is mounted on a Weaver 1o'clock rail mount with standard Leupold scope for distance and DeltaPoint for close in work. The rifle is a alexander arms 6.5 Grendal. The biggest down side I have found is sight adjustment, it takes a T5 torx wrench and two adjustment screws. (translation, don't lose the torx wrench that comes with the sight)
Pros: Very easy to see the delta, comes on as soon as the weapon is moved
Cons: No off switch for transport. Needs a T5 torx drive to change sight position.
