Primary Arms Optics is known for manufacturing modern optical sights for the entire range of applications. These models are supplied to specialist retailers and are also available at the US brand specialist Ferkinghoff International. The catalog includes riflescopes, mounts, red dots and binoculars. The Texan company is managed by a team of experienced marksmen, shooting sports enthusiasts and (former) military personnel. According to the company, their aim is to offer high-quality optics at favourable prices. Primary Arms optics are available in the categories Platinum - PLx, Gold - GLx, Silver - SLx and the Classic Series - CLx:
Overview: Categories / Series of Primary Arms optics
Platinum Series (PLx)
The Platinum series comprises high-quality riflescopes that are manufactured in Japan and are designed to impress with superior glass quality and first-class materials. According to Primary Arms, the housing features of these scopes are built to maximise the performance of the latest ACSS reticles. The PLx range is designed to compete with scopes from other top brands in the USA and Europe.
Gold Series (GLx)
The new Gold series is developed in Houston, Texas, and, according to Primary Arms, manufactured in the Philippines to the manufacturer's strict standards. Equipped with the latest technology and top materials, GLx optics are designed to offer elegant and innovative solutions for precise shooting.
Silver Series (SLx)
According to the company, optics from the silver series form the centerpiece of the PA range. These optics have contributed significantly to the reputation of Primary Arms Optics over the years. Nevertheless, the company is constantly developing new generations and expanding its range, according to the manufacturer.
Classic Series (CLx)
With the classic series, Primary Arms Optics wants to show that entry-level optics do not necessarily have to be of inferior quality. CLx series optics are designed to appeal to price-conscious buyers and newcomers to the shooting sport in particular. The quality control of the optics is carried out 100% at Primary Arms in Houston.
Primary Arms Classic Series 21mm Micro Reflex Sight Gen2 with Autolive function and 3 MOA red dot for compact pistols
The MRSC Sight from the Classic series comes with Autolive. This function switches the device off automatically after a period of inactivity and switches it on again at the slightest movement. This ensures a longer battery life. The Micro Reflex Sight is specially optimised for compact and sub-compact pistols that are carried concealed. The sight has a slightly reduced 21x15 mm lens, which keeps the profile as slim as possible and prevents it from protruding sideways over the slide of smaller pistols.
Despite the smaller lens compared to the mini model, the square profile offers an unobstructed field of view. The sight utilises the RMSc footprint, which enables broad compatibility with optics cuts and adapter plates. Power is supplied by a bottom-mounted CR2032 battery, which is said to offer up to 40,000 hours of runtime at medium setting. The sight comes with 10 brightness settings and a 3-MOA dot, which should be clearly visible even in daylight. According to the manufacturer, the 6061 aluminum housing is extremely robust, while the multi-coated lens offers scratch and fog resistance. The red dot is available from Ferkinghoff International for a price of 225 euros (RRP).

The reflex sight features the widely used 507c footprint (Trijicon RMR), which also ensures broad compatibility.

Primary Arms GLx RS-15 Mini Reflex Sight: available with ACSS Vulcan Dot reticle – here comes the upper class!
The GLx RS-15 is part of Primary Arms' upper-class Gold series, which aims to offer high-quality technology and materials in a still affordable price segment. With the RS-15, Primary Arms Optics aims to define the next generation of pistol optics. It features a larger viewing window, a 7075 aluminum housing and, like the SLx RS-10, it comes with a GLOCK MOS mounting plate that offers broad compatibility with various pistol slides. The footprint of the RS-15 is the same as that of the C-More. The side-mounted brightness buttons allow easy operation, while the top-mounted battery compartment allows the CR2023 cell to be changed quickly without removing the sight.
The sight is available with a conventional 3-MOA dot as well as with the ACSS Vulcan dot reticle, which provides a precise dot with an outer ring. The ring lies outside the visible lens and is intended to provide a quick reference for target acquisition in order to avoid aiming errors. We have already presented the sight and reticle in more detail here at all4shooters.com.
New to this series are the 0.5 MOA adjustments for windage and elevation, which are intended to enable even finer adjustment when firing. The manufacturer is thus catering for sports shooters in particular. Improved lens coatings ensure outstanding clarity and the extended lens facilitates quick target changes. The Autolive functionality is also on board again with this sight. The GLx RS-15 is also designed to be waterproof and shockproof. Ferkinghoff International lists the sight at a price of €475 with the ACSS Vulcan reticle and €425 with a conventional dot.
