Primary Arms SLx 1-10x28mm 34mm Tube Rifle Scope, Second Focal Plane Review

First Impressions of Primary Arms SLx 1-10x28mm 34mm Tube Rifle Scope, Second Focal Plane

The Primary Arms SLx 1-10x28mm 34mm Tube Rifle Scope, Second Focal Plane promises to be a versatile optic, bridging the gap between red dot speed and magnified precision. This scope, manufactured by Primary Arms, boasts a 1-10x magnification range and the innovative ACSS NOVA reticle, aiming to provide both rapid target acquisition and accurate long-range holds. The 34mm tube suggests robust construction and ample adjustment range, making it an interesting contender in the crowded LPVO (Low Power Variable Optic) market.

I needed a scope that could handle close-quarters drills as effectively as engaging targets out to several hundred yards. My old 1-6x wasn’t cutting it for precision work, and switching between a red dot and a separate magnified optic was cumbersome. I was seeking a true do-it-all optic and the Primary Arms SLx 1-10x28mm seemed to fit the bill.

Unboxing the SLx 1-10x28mm revealed a well-packaged optic. The scope felt solid and well-built, a definite step up from some of the cheaper LPVOs I’ve handled. The finish was clean, and the turrets had a positive, audible click.

I considered the Vortex Viper PST Gen II 1-6x and the Trijicon Credo 1-8x before settling on the Primary Arms SLx 1-10x28mm. The Vortex, while excellent, lacked the magnification range I desired, and the Trijicon’s price was significantly higher. The Primary Arms offered a compelling combination of features and affordability.

My first impression was one of cautious optimism. The build quality seemed excellent, and the ACSS NOVA reticle looked promising. I was eager to mount it and see how it performed in the real world.

Real-World Testing: Putting Primary Arms SLx 1-10x28mm 34mm Tube Rifle Scope, Second Focal Plane to the Test

First Use Experience

My initial testing took place at an outdoor shooting range, engaging targets from 25 to 500 yards. The weather was clear and sunny, providing ideal conditions for evaluating the scope’s optical clarity and reticle illumination. I mounted it on my AR-15, a platform I’m intimately familiar with, to provide a consistent baseline.

The 1x setting felt very close to a true 1x, allowing for rapid target acquisition similar to a red dot. The illuminated ACSS NOVA reticle was easily visible in bright daylight, a crucial feature for close-quarters work. As I zoomed to higher magnifications, the image remained clear and bright, even at 10x.

The only initial issue was adjusting to the eye relief at higher magnifications; it’s a bit tighter than my previous optic. After a few adjustments and getting used to the proper cheek weld, this became less of an issue.

Extended Use & Reliability

After several months of use, the Primary Arms SLx 1-10x28mm has proven to be a reliable and versatile optic. It has accompanied me on several range trips and even a weekend hunting trip (though I didn’t get a shot opportunity). The scope has held zero consistently, even after being bumped around in my rifle case.

Cosmetically, the finish has held up remarkably well, showing only minor signs of wear around the turret caps. I’ve wiped it down with a microfiber cloth after each use, and the lenses remain clear and scratch-free. The scope is also waterproof, which came in handy during an unexpected downpour at the range.

Compared to my previous 1-6x scope, the Primary Arms SLx 1-10x28mm offers a significant improvement in long-range capabilities. The extra magnification allows for more precise shot placement at extended distances, and the ACSS NOVA reticle provides intuitive holdovers for various ranges.

Performance & Functionality

The Primary Arms SLx 1-10x28mm excels in its intended role as a versatile LPVO. Its accuracy is excellent, consistently delivering tight groupings at various ranges when paired with a quality rifle and ammunition. The 1x setting is truly usable for close-quarters engagements, while the 10x setting provides ample magnification for identifying and engaging targets at longer distances.

A significant strength is the ACSS NOVA reticle. The illuminated center dot is incredibly fast to acquire, and the integrated ranging and holdover features are surprisingly intuitive. A slight weakness is that the reticle can appear a bit busy at times, especially at lower magnifications.

Accessories and Customization Options

The Primary Arms SLx 1-10x28mm itself doesn’t come with a plethora of accessories, but its compatibility with standard 34mm scope mounts opens up a wide range of customization options. A quality scope mount is essential for ensuring proper alignment and consistent performance.

The scope is also compatible with various aftermarket throw levers, which can make magnification adjustments even faster and easier. Since it is a SFP scope, it is very important that you pair it with a ballistic calculator that supports Second Focal Plane scopes.
