A strong value pick for AR shooters wanting clear glass and an illuminated reticle at 3x, though check eye relief carefully if mounting on an AK or similar side-rail setup.

Clear glass and a bright etched reticle at a low price, but confirm eye relief fits your rifle's rail position before buying.

A capable long-range FFP scope for the price, though a minority of units arrive with lens or illumination defects that Monstrum has replaced on request.

A solid low-cost scope for .22LR and closer-range rifles that holds zero, but confirm mount compatibility first and don't expect the illumination to show up in bright sun.

A first focal plane scope with accessories included that punches above its price, though the turret feel and top-end eye box are rougher than pricier optics.




A dependable low-cost LPVO that holds zero under real use, with the honest caveat that glass clarity trails pricier scopes.

A capable low power variable scope for the price, with clear glass and a mount included, but budget for slightly more weight and a tighter eye box than the listing suggests.

Owners who compare it to pricier scopes still call the glass on this Guardian clear and the turrets precise, with tight eye relief as the main trade-off.

A capable prism scope for the price, with an etched reticle that stays visible even if the illumination battery runs out, and zero retention reviewers confirm under recoil.

A clear, well-regarded budget prism scope for AR rifles, particularly for shooters with astigmatism, though eye relief needs some setup attention and Shake Awake didn't work for every buyer.

Reviewers rate the glass quality and zero retention highly for the price, with weight and 1/2 MOA click spacing being the main tradeoffs worth knowing beforehand.

A well-reviewed budget LPVO that holds zero for most buyers and includes a mount worth using on its own, though at least one unit's reticle drifted after a couple hundred rounds.

A capable FFP LPVO for its price point, with ED glass reviewers describe as clear, though the exoskeleton mount adds real, measurable weight over a standard tube.

A wide-range FFP LPVO with ED glass aimed at shooters who want one scope to handle both close and mid range work.
