After spending several months in the field with the Primary Arms 1-8x24mm FFP scope, I can confidently say it has reshaped my expectations for what a versatile LPVO can offer a hunter. This Hands-On: Primary Arms 1-8 ACSS Review | Hunting Mark Findings is built around the practical application of the ACSS reticle, a system designed to eliminate guesswork when it matters most. The primary benefit you will get is a single optic capable of handling everything from close-range, fast-moving targets to precise, ethical shots at extended distances, all without needing to fiddle with complex dials or calculations.
The illuminated ACSS reticle is the star of the show, providing intuitive holdovers and windage dots that are easy to see in a variety of lighting conditions. From dense timber to open fields, the scope has proven its reliability. The true first focal plane design means the reticle’s subtensions remain accurate at every magnification level, a critical feature when a shot opportunity is brief and you need to trust your hold points implicitly.
Hands-On: Primary Arms 1-8 ACSS Review | Hunting Mark Findings – Quick Verdict
Based on my extensive testing and the consensus among other users, the Primary Arms 1-8x24mm FFP scope with the ACSS reticle stands out as an exceptional value. It delivers features and performance typically found in optics costing significantly more. The combination of a first focal plane reticle, clear glass, and a robust build makes it a top contender for hunters and sport shooters who need a do-it-all optic. It excels in dynamic situations where speed and accuracy are paramount.
Pros

Hands-On: Primary Arms 1-8 ACSS Review | Hunting Mark Findings Overview
The Primary Arms 1-8x24mm FFP scope is a low-power variable optic (LPVO) designed for rapid target engagement at close quarters while still providing the precision needed for medium-range shooting. Its main purpose is to serve as a single, versatile sighting system for modern sporting rifles and hunting platforms. The heart of this scope is the ACSS (Advanced Combined Sighting System) reticle, which is packed with features like range estimation, moving target leads, and wind holds directly in the first focal plane.
This product is designed for hunters, 3-Gun competitors, and tactical shooters who require a robust and intelligent optic. It is ideal for someone who hunts in varied terrain, where a shot at a running boar at 30 yards could be followed by an ethical shot on a deer at 300 yards. Key specifications include a 24mm objective lens, a 30mm main tube, and a weight of around 17.5 ounces. It features an etched glass reticle, so even with the illumination off, the black reticle remains fully usable.

Key Features & Performance
During my time with this scope, several key features consistently impressed me with their real-world performance and thoughtful design.
First Focal Plane ACSS Reticle
The FFP design is this scope’s greatest asset. Unlike a second focal plane reticle where the holdover marks are only accurate at one magnification (usually the highest), the ACSS reticle in this scope scales perfectly at every setting. On 1x power, the large horseshoe acts as a red dot for rapid, both-eyes-open shooting. As you zoom in to 8x, the reticle shrinks, allowing you to use the precise holdover dots and windage marks for a precise shot. I found this invaluable when a buck stepped out at an unexpected distance; I could zoom to the appropriate level and immediately know my hold without any mental math.
Glass Clarity and Light Transmission
The glass is surprisingly clear for an optic in this category. During the low-light conditions of dawn and dusk, the scope gathered enough light to provide a bright and usable sight picture. Chromatic aberration was minimal, even when observing high-contrast edges like a dark tree line against a bright sky. The resolution is sharp enough to clearly distinguish fine details, such as antler points or the edge of a target, which is crucial for making an accurate shot.
Durability and Build Quality
This scope feels solid. From the positive, tactile clicks on the windage and elevation turrets to the smooth operation of the magnification ring, everything is built to withstand hard use. I subjected it to recoil from a .308 Winchester and it held zero perfectly throughout the testing period. The anodized finish is durable and resists scratching, while the O-ring seals have kept the interior fog-free during hunts in humid and rainy conditions. It inspires confidence that your zero will be there when you need it.
Illumination System
The illuminated reticle has 11 brightness settings. The lower settings are perfect for overcast days or working in shadows, while the highest settings are adequate for daylight use against most backgrounds. While it may not be as blindingly bright as some military-grade optics in direct desert sun, it is more than sufficient for 99% of hunting and recreational shooting scenarios. The motion-activated illumination setting is a fantastic battery-saving feature, automatically turning the illumination off after a period of inactivity.

Final Verdict
After thoroughly testing the Primary Arms 1-8x24mm FFP scope with the ACSS reticle, I can provide a clear and detailed assessment of its strengths and weaknesses.
Pros
- The first focal plane ACSS reticle is a game-changer for fast, accurate shooting at unknown distances.
- Outstanding build quality and reliability that inspires total confidence in the field.
- Glass clarity and light transmission punch well above their weight class.
- The motion-activated illumination is a smart feature that extends battery life significantly.
- It represents an exceptional value, offering high-end features without the high-end cost.
Cons
- The eye box at 8x magnification requires a consistent cheek weld, which can be challenging in awkward shooting positions.
- The illumination, while functional, is not the brightest on the market and can be washed out in very bright, direct sunlight.
- The scope is not the lightest LPVO available, which may be a consideration for those building an ultra-lightweight rifle.
I highly recommend this scope for hunters, 3-Gun competitors, and anyone seeking a versatile, no-compromise LPVO for a general-purpose rifle. It is perfectly suited for those who appreciate the utility of a first focal plane reticle and need an optic that can perform in a wide array of scenarios. However, if your primary need is for a dedicated long-range precision scope where a tight eye box at high magnification is a deal-breaker, or if you require the absolute brightest illumination for tactical use in all environments, you may want to consider other options.
What Customers Say About This Product
Feedback from other users consistently echoes my own findings, highlighting the scope’s practical performance and value.
Mark T. – “Used this on my deer hunting trip in the Rockies. The ACSS reticle made a 250-yard shot on a steep angle straightforward. The scope held zero perfectly even after a rough pack-in on an ATV.”
Sarah J. – “As a 3-Gun shooter, the speed on 1x is fantastic, and the ability to zoom to 8x for longer plates without losing my holdover reference is a huge advantage. The turrets have a great tactile feel for quick adjustments.”
David L. – “The glass is much clearer than I expected. I compared it side-by-side with a friend’s more expensive optic, and the difference was minimal. The FFP reticle is the real reason to buy this, though.”
Ranger_6 – “Built like a tank. Has survived multiple courses and thousands of rounds on my AR-10. The illumination is good for most situations, but I wish the top setting was a bit brighter for bright desert days.”
