However, the Primary Arms SLx 3-18x50mm First Focal Plane (FFP) Rifle Scope with the advanced ACSS APOLLO .308/6.5 Grendel Reticle shatters these expectations, delivering a premium long-range solution that truly punches far outside its weight class.

This optic isn't just another scope; it's a meticulously engineered tool designed to simplify complex ballistic challenges, enabling shooters to achieve consistent accuracy out to 1,000 yards and beyond. Whether you're engaging distant steel targets, tracking game across varied terrain, or pushing the limits of your .308 Winchester or 6.5 Grendel rifle, this SLx series scope provides the confidence and capability you need.

Who is the Primary Arms SLx 3-18x50mm FFP Scope Designed For?

This scope is an ideal choice for a diverse range of shooters seeking unparalleled performance and simplicity in their long-range engagements:

• .308 Winchester and 6.5 Grendel Owners: If your rifle is chambered in either of these popular calibers, the ACSS APOLLO reticle is custom-tuned to provide immediate, math-free holdovers and wind corrections.
• Hunters: From whitetail deer to elk, the 3-18x magnification range offers versatility for both close-in timber shots at 3x and precise long-range placements at 18x. Its robust construction ensures reliability in harsh environments.
• Competitive Shooters (e.g., PRS/NRL/Long-Range Steel): The intuitive ACSS reticle allows for rapid target engagement without constant turret adjustments, keeping you focused on the shot. The FFP design ensures accurate ranging and holdovers at any magnification.
• Precision Rifle Enthusiasts: Those who demand precise adjustments, clear glass, and a durable build will appreciate the tactile turrets, crisp image, and the SLx reputation for reliability.
• Recreational Shooters: If you enjoy pushing the boundaries of your rifle's capabilities and want to consistently hit distant targets without complex ballistic calculators, this scope simplifies the process significantly.

Solving the Challenges of Long-Range Shooting: The ACSS APOLLO Advantage

One of the biggest hurdles in long-range shooting is accurately compensating for bullet drop (BDC) and wind drift. Traditional methods often involve tedious calculations, guessing wind speeds, or constantly dialing turrets, which can be time-consuming and error-prone, especially under pressure. The Primary Arms SLx 3-18x50mm FFP scope, equipped with the revolutionary ACSS APOLLO .308/6.5 Grendel Reticle, provides an elegant solution.

Imagine a scenario where you've spotted a target at an unknown distance. With the ACSS APOLLO, you simply use the built-in ranging stadia to determine the approximate range, then apply the corresponding holdover mark on the reticle for bullet drop. Simultaneously, the integrated wind dots provide precise wind corrections for up to 20 mph crosswinds. All of this happens instantly within your field of view, eliminating the need for external tools or excessive turret manipulation. It's truly a "sight in at 100 yards and you're ready to engage at any range out to 1,000 yards" system.

Key features of the ACSS APOLLO Reticle that empower this capability include:

• Built-in Range Estimation: Quickly and accurately determine target distance using intuitive ranging ladders.
• Bullet Drop Compensation (BDC): Pre-calibrated drop points for .308 Winchester and 6.5 Grendel allow for instant holds out to 1,000 yards.
• Wind Holds: Integrated wind dots provide immediate compensation for crosswinds up to 20 mph, ensuring your shot stays on target even in challenging conditions.
• Chevron Central Aiming Point: This infinitely small aiming point allows for unparalleled precision, ensuring you can hit even the smallest targets at extreme distances without obscuring your view.
• .2 MIL Crosshair Subtensions: Fine subtensions provide additional reference points for precise adjustments or measuring targets.

This First Focal Plane (FFP) design is crucial for the ACSS APOLLO's effectiveness. In an FFP scope, the reticle physically grows and shrinks with magnification. This means that all the ranging, holdovers, and wind holds remain 'true' and proportional at every magnification setting. Whether you're at 3x for a quick close shot or 18x for a thousand-yard engagement, the values represented by the reticle's markings remain consistent, eliminating the need for recalibration or mental math when changing power settings.

Versatility from 3x to 18x Magnification

The broad 3-18x magnification range makes this scope incredibly versatile, adapting to a multitude of shooting scenarios.

• Low Magnification (3x): At 3x, the scope offers a wide field of view (36.70 ft at 100 yards) and a bright, daylight-visible illuminated reticle, making fast snap shots at close to medium range a breeze. It's excellent for tracking moving targets or acquiring targets quickly in dense brush. The forgiving exit pupil (16.20 mm) and eye relief (3.90 in) contribute to rapid target acquisition.
• High Magnification (18x): When cranked up to 18x, the scope allows shooters to clearly identify and engage targets at extended distances, easily reaching the 1,000-yard line. The objective diameter of 50mm ensures excellent light transmission even at higher magnifications, providing a bright and clear image. The eye relief at high magnification remains generous (3.50 in), minimizing eye strain.

Robust Construction and Ergonomic Excellence

Beyond its optical performance, the Primary Arms SLx 3-18x50mm FFP scope boasts a robust build and thoughtful ergonomic features designed for real-world use. As part of the SLx optics line, it inherits a reputation for innovation, reliability, and exceptional value. All SLx optics undergo rigorous field-testing during development, ensuring they can withstand the toughest environments and perform flawlessly when it matters most.

• Improved Turrets: The scope features new and improved turrets with tactile and audible 0.1 MIL click adjustments, providing precise and repeatable feedback for zeroing or making minor adjustments. Once you've achieved your zero, the turrets offer easy reset capability and secure locking to prevent any accidental adjustments during transport or vigorous activity.
• Intuitive Illumination: The illumination turret provides six distinct settings with an 'OFF' position conveniently located between each setting. This allows for fast switching to your preferred brightness level without cycling through unwanted settings, optimizing reticle visibility in varying light conditions. The reticle is partially illuminated, focusing illumination where it's most critical for aiming.
• Removable Power Ring Fin: A unique and highly practical feature is the removable and replaceable fin on the power ring. This fin acts like a magnification throw lever, allowing for rapid adjustment of the magnification range with minimal effort. Its placement is entirely at the discretion of the operator, enabling customization for optimal ergonomic access.
• Optical Clarity and User Comfort: Featuring clear glass, the scope provides a crisp and vibrant image across its magnification range. Combined with forgiving eye relief and exit pupil characteristics, it promotes comfortable viewing even during extended periods of use. A smooth parallax adjustment works in conjunction with a fast-focus eyepiece to ensure a perfectly crisp image of both the target and the reticle, eliminating parallax error at various distances.
• Durability Standards: The 30mm main tube offers excellent structural integrity. This scope is engineered to be waterproof, fog resistant, and shock resistant, guaranteeing performance in rain, humidity, or after accidental impacts. Its overall weight of 25.4 oz (with battery, without lens covers) strikes an excellent balance between robustness and manageable carry.
