Gun Optics & Sights – Compare Prices

The Holosun 403 and 503 series ($120 to $180) offer shake-awake, 50,000-hour battery life, and proven reliability. For a step up, the Aimpoint Duty RDS ($400) gives you Aimpoint durability at a mid-range price. The SIG Romeo5 ($100 to $130) is excellent for budget AR-15 builds.

For general use inside 300 yards, a 1-6x or 1-8x LPVO covers everything from CQB to medium range. For precision shooting at 500+ yards, a 4-16x or 5-25x gives you the magnification to read wind and spot hits. For hunting, a 3-9x is the classic all-rounder.

First Focal Plane (FFP) reticles stay accurate at every magnification, which matters for holdover and ranging. Second Focal Plane (SFP) reticles are only accurate at one magnification but appear larger and clearer at low power. FFP is better for precision and competition. SFP is fine for hunting and general use.

For AR-15s with flat-top receivers, standard or low mounts work for most scopes. If you run a scope with a 50mm+ objective lens, you may need medium or high rings. For bolt-action rifles, low rings give the best cheek weld. Always check that the objective bell clears the barrel or handguard.

For rimfire and light-recoiling rifles, budget rings from Vortex or Primary Arms work fine. For heavy-recoiling rifles (.308, .300 Win Mag) or duty use, spend the money on quality rings from Vortex Pro, Warne, Badger Ordnance, or Scalarworks. A $30 ring on a $1,000 scope is a bad idea.

The most common pistol red dot footprints are: RMR (Glock MOS, many aftermarket slides), RMSc/Shield (SIG P365, Springfield Hellcat, S&W Shield Plus), Acro (some HK, Walther), and DeltaPoint Pro (some Beretta, FN). Check your slide cut before buying.

Most modern red dots last 20,000 to 50,000 hours on moderate brightness. Holosun and SIG Romeo models with shake-awake technology extend this further by sleeping when not in use. Aimpoint T-2 and Duty models are rated for 50,000 hours of constant-on use. Replace batteries annually on carry and duty guns regardless.

For duty and defensive rifles, yes. Electronics can fail, batteries can die, and lenses can break. Co-witness iron sights (lower 1/3 or absolute) give you a backup aiming solution. For range-only guns, they are nice to have but not critical.
