Sights:
- Red dots need adjustments to avoid vanishing (too weak) or ‘blooming’ (too strong) depending on lighting conditions.
- Red dot sights tend to ‘fuzz out’ (astigmatism) with (shooter’s) age.
- Low-Power Variable Scopes
- 1x-4x, 1x-5x, 1x-6x, etc.
- Used by lots of military special forces
- Have the lowest magnification as the initial & default. Once on target, then ramp it up – otherwise, like searching through a straw.
- Throw levers can make the magnification adjustment significantly easier.
- Expect scope + mount to be ~½ of cost of rifle. (LaRue mounts.)
- With good quality mounts (indexed and repeatable) can hot-swap between red dot and scope.
