Iron Hill Armory stocks a wide range of dependable gun scopes designed to deliver clear sight pictures, accurate holds, and consistent performance for hunters, target shooters, and precision marksmen. These optics pair seamlessly with our wide range of rifles for long-range precision, handguns for competition and self-defense, and shotguns for hunting and slug-gun applications. We also carry rifle ammunition, gun sights, and red dot sights from a variety of manufacturers to dial in accuracy at the range or in the field.
Shop gun scopes online by comparing models, checking current availability, and reviewing specifications such as magnification range, objective lens diameter, reticle type, and tube diameter. Gun scopes improve accuracy and target identification by giving shooters a magnified, clear view of their target along with reference points for holdover and windage corrections.
Here’s what to consider before mounting a new optic:
Buy gun scopes online or visit our gun shop in St. James, Missouri to look through models in person before buying. Iron Hill Armory also serves customers from nearby cities including Rolla, Cuba, Salem, and Steelville.
Gun scopes themselves are not regulated as firearms, but optics ordered alongside firearms follow federal guidelines and applicable Missouri requirements, which typically involve shipment to a licensed dealer and completion of a background check prior to pickup. Shipping timelines vary by product, so review checkout information carefully before placing your order.
Mounting practices, zeroing routines, and storage responsibilities may differ based on circumstances. Contact the shop directly for clarification on product compatibility, accepted identification, and current store policies.
Lower magnifications like 1-4x or 1-6x suit close to medium range work, while 4-16x and higher fits long range shooting. Match the magnification to the typical distances you shoot.
MOA and MIL are different units for measuring angles in scope adjustments. Pick whichever system you find easier to calculate and stick with it across your scopes.
First focal plane reticles scale with magnification, keeping holdovers accurate at any zoom level. Second focal plane reticles stay the same size and work well when shooting at a single magnification.
30mm tubes are common and offer more elevation travel than 1 inch tubes, while 34mm and 35mm tubes give even greater adjustment range. Larger tubes also typically allow for more robust construction.
You can, but you’ll need to re-zero the scope each time it’s mounted on a different rifle. Most shooters dedicate scopes to specific rifles for consistency.
Parallax adjustment removes the apparent shift between the reticle and target when your eye moves behind the scope. It’s especially important for precision shooting at varying distances.
Bore sight first to get on paper, then fire groups at a known distance and adjust windage and elevation until rounds hit point of aim. Confirm with multiple groups before finalizing your zero.
Use mounts rated for your firearm’s recoil and matched to your scope’s tube diameter. Quality rings or one-piece mounts ensure the scope holds zero under repeated use.
