It depends on how you plan to use your rifle. For close to mid-range shooting (100–300 yards), a 1-4x or 1-6x LPVO (Low Power Variable Optic) is ideal. For longer-range accuracy (400+ yards), look for scopes with 3-9x or 4-12x magnification.

For tactical and home defense setups, red dot sights and LPVOs are top choices. They offer fast target acquisition and wide fields of view, making them perfect for close-quarters engagements.

Yes, many hunters use scopes like 3-9x or 4-12x for varmint and predator hunting. Just make sure the scope is rated to handle the recoil and mounting system of your AR platform.

Red dots offer zero magnification and are built for quick target acquisition at short ranges. Magnified scopes provide adjustable zoom, helping you shoot accurately at longer distances.

Most AR-15s use a Picatinny rail system. Make sure your scope rings or mount are compatible with Picatinny rails and provide the right height for a comfortable cheek weld and clear sight picture.

FFP (First Focal Plane) scopes change the reticle size with magnification, which helps with ranging and holdovers at any zoom level. SFP (Second Focal Plane) scopes keep the reticle size constant, which many shooters find easier to use at low magnification.

Yes, most high-quality AR-15 scopes are nitrogen or argon purged and sealed to be both waterproof and fog-resistant. Always check the product specs for IP ratings or weather resistance details.
