Magnification by Use Case
| Use Case | Magnification | Examples | Price Range |
|---|---|---|---|
| Home defense / CQB | 1x or 1–4x LPVO | Vortex Strike Eagle 1-6x, Primary Arms SLx 1-6x | $150–$400 |
| Hunting (100–300 yds) | 3–9x or 2–10x | Leupold VX-Freedom 3-9x, Vortex Diamondback 3-9x | $200–$500 |
| Precision / Long Range | 4–16x or 5–25x | Vortex Viper PST Gen II, Nightforce NX8 | $600–$2,000+ |
| Competition / 3-Gun | 1–6x or 1–8x LPVO | Kahles K16i, Steiner P4Xi | $800–$2,500 |
FFP vs SFP Reticles
First Focal Plane (FFP) — reticle scales with magnification. Holdovers and ranging are accurate at any power setting. Preferred for variable-power precision shooting. Downside: reticle appears very small at low magnification.
Second Focal Plane (SFP) — reticle stays the same size regardless of magnification. Holdovers only accurate at max power. More common in hunting scopes. Easier to see reticle at low magnification.
MOA vs MRAD
MOA (Minute of Angle) = 1.047" at 100 yards. Most US shooters use MOA. Standard adjustment: ¼ MOA per click = ~0.26" at 100 yards. MRAD (Milliradian) = 3.6" at 100 yards. Preferred by military and metric-system shooters. Standard: 0.1 MRAD per click = 0.36" at 100 yards. Both systems work equally well — pick one and stay consistent with your scope and turrets.
Red Dots vs LPVOs
Red dot sights (RDS) like the Aimpoint PRO (~$480) or Trijicon MRO (~$380) offer unlimited eye relief, fast target acquisition, and parallax-free operation at typical defensive distances — ideal for defensive ARs and under 100-yard shooting. Battery life on quality RDS units runs 3–5 years on a single CR2032.
LPVOs (Low Power Variable Optics) at 1–6x or 1–8x cover both close-quarters at 1x and medium-range precision. The tradeoff: heavier, more expensive, require consistent eye relief positioning.
Scope Mounts & Rings
Mounts must match tube diameter: 1" or 30mm (most common), 34mm (premium long-range). Torque specs matter — undertorqued rings shift zero; overtorqued rings damage the scope tube. Recommended: 15–18 in-lb on ring screws, 65 in-lb on Picatinny cross-bolts.
- Aero Precision Ultralight 30mm — QD, excellent value. (~$55)
- Vortex Pro QD Mount 30mm — strong return to zero. (~$99)
- ADM AD-RECON — competition-grade QD. (~$145)
- Warne RAMP Rings — traditional fixed rings, very secure. (~$70/pair)
