CLx is Primary Arms' current entry-tier optics line, sitting above the older Classic Series 1x and 25mm tube sights but below the SLx mid-tier. The four launches dropping in June 2026 round out the line with the categories shooters most often ask for at sub-$220: a tube-style micro red dot, an enclosed pistol-ready reflex, and a pair of prism scopes for AR-15 use. Every CLx optic carries the same Primary Arms lifetime warranty that protects SLx, GLx, and PLx purchases, which is the single biggest reason this tier exists. You are not buying a stripped warranty product, you are paying less for simpler reticles and slightly less refined glass and controls.

The pricing matters because the rest of the budget red dot market has crept up over the last 18 months. Holosun pushed the HE403B-GR and HE503CU above $180, Sig moved the Romeo5 X compact past $200, and EOTech does not play in this bracket at all. A $149 red dot with a lifetime warranty and a CR2032 that lasts 10,000+ hours is now a hard product to find from an established brand. CLx is Primary Arms' answer. If you are shopping the broader category, our best budget AR-15 optics under $200 guide covers how Sig, Holosun, and Primary Arms stack up at this tier.

The RD-23 is the headline price-point optic of the new lineup. A 23mm tube red dot with a 3 MOA dot, T1/T2 mount footprint, CR2032 battery rated for 10,001 to 25,000 hours depending on brightness, 10 illumination settings with two night-vision positions, and a solar backup cell. It is built on hardcoat anodized 6061 aluminum, weighs 3.5 oz, measures 2.27 inches long, and uses 1 MOA windage and elevation clicks. A 1913 Picatinny mount is included in the box.

The push-button brightness controls on the left side of the tube are the key differentiator from the SLx RS-10 ($209.99) and the Holosun HE403B-GR. Rotary brightness knobs catch on cover garments and slings; flush push buttons do not. For a dedicated home defense or duty AR where the optic stays at one brightness most of the time, the buttons are functionally identical to the knob. For shooters who routinely transition between indoor and outdoor light, the button latency is noticeable but acceptable. The solar backup is the safety net: if the CR2032 dies, the optic stays usable in daylight without user intervention.

At $149.99 the RD-23 is the cheapest current-production T1/T2-footprint micro red dot with a lifetime warranty from an established US brand. It pairs naturally with PSA, Aero, and Smith & Wesson M&P15 builds where the buyer is already budget-conscious. For deeper context on T1/T2 mount selection and co-witness heights, see our AR-15 optic mounting guide.

The CLx Enclosed Reflex Sight is the most strategically interesting product in the launch. A fully enclosed RMSc-footprint micro red dot with a 3 MOA dot, 21x17mm clear aperture, 1 MOA clicks (60+ MOA windage and elevation), AutoLive motion-activated illumination, and a CR1632 battery rated for 21,000 hours on medium. It weighs 0.98 oz, measures 1.61 inches long, includes integrated backup iron sights, and uses a side-loading battery tray that does not lose zero. Ten brightness settings: eight daytime and two night-vision compatible. Lifetime warranty. List price $179.99.

RMSc footprint matters because that is the cut found on the subcompact carry-pistol segment driving optic adoption: the Sig P365 XL and P365 X-Macro, Springfield Hellcat OSP, Smith & Wesson Shield Plus, and Glock 43X/48 MOS. Until 2025 the only enclosed RMSc options were the Sig Romeo Zero Elite at $300+, the Holosun EPS Carry at $399+, and the Holosun SCS RMSc at $470+. The Phoenix-based Osight SE cracked the floor open at $125-169 street last year, and the CLx Enclosed at $179.99 is the second value-tier entrant to clear it.

Head-to-head with the Osight SE the spec sheets are nearly identical: both weigh 0.97-0.98 oz, both run 1.59-1.61 inches long, both side-load the battery, and both ship with eight daylight plus two night-vision brightness settings. The Osight wins on battery (CR1620 rated 75,000 hours vs the CLx's CR1632 at 21,000), housing alloy (7075 vs 6061), and reticle variety (the standard SE ships a multi-reticle 2 MOA dot / 32 MOA circle layout; a separate SE green 6 MOA dot SKU exists). Both ship with integrated backup iron sights on the housing. The CLx counters with a larger 3 MOA dot that is faster to pick up at speed and the established Primary Arms warranty network. Pew Pew Tactical's SE review also flagged water-ingress problems despite the IPX7 rating, a track-record concern that Primary Arms' 20-year US warranty operation does not carry.

The buy case is straightforward: if you are running a P365 or Hellcat-class carry pistol and you want the established Primary Arms US warranty operation behind the optic, the CLx Enclosed is the pick. If you want the longer battery life, harder 7075 housing, and a multi-reticle option at a slightly lower street price, the Osight SE still has the edge. Either one is a meaningful step up from no optic, and both undercut the Holosun enclosed line by $200 or more.

The CLx 1x Prism is the budget answer to Primary Arms' own SLx 1x MicroPrism, which sells for $264.99. Same general format: a 1x fixed prism scope with a red-illuminated etched reticle, 18mm objective, 16.5mm exit pupil, Aimpoint Micro footprint, 10 brightness settings with two NV positions, and a CR2032 battery rated for 2,000 hours on medium. Hardcoat anodized aluminum, fully multi-coated optics, nitrogen-purged waterproof construction, adjustable diopter. Includes a 1913 MIL-STD Picatinny mount at 1.41 inches centerline above the rail. Weighs 6.63 oz at 2.35 inches long.

The reticle is a 3 MOA center dot inside a 45 MOA outer circle, a layout borrowed from the EOTech 65/1 design. The center dot anchors precision shots; the outer ring drives the eye for close-quarters target acquisition. It is not as specialized as the SLx's ACSS Cyclops Gen II reticle (which adds BDC subtensions and ranging chevrons), but for shooters under 200 yards the circle-dot is functionally equivalent and easier to learn.

The headline feature for many buyers will be the etched reticle. Shooters with astigmatism, even mild astigmatism, see emitter-projected red dots as starbursts, comet tails, or smeared blobs. Etched prism reticles stay crisp because the eye sees a physical engraving rather than a focused light source. If you have tried a Holosun or Aimpoint and the dot looks fuzzy, a prism scope is the fix. See our red dot vs prism vs LPVO comparison for the full decision framework.

The CLx 3x Prism is the most capable optic in the lineup and the one that competes most directly with the budget LPVO market. Fixed 3x magnification on a 30mm objective, 8mm exit pupil, 2.72 inches of eye relief, 38.2 ft field of view at 100 yards, etched 5.56-optimized Cross Dot reticle, 100 MOA of windage and elevation in 1/4 MOA clicks, Aimpoint T1/T2 mount footprint, CR2032 battery, 10-position illumination with two NV positions. Weighs 7.32 oz at 3.01 inches long. Mount included.

At $219.99, the 3x Prism is roughly the same money as a Vortex Strike Eagle 1-6x at street price but with a fundamentally different value proposition. The Strike Eagle gives you variable magnification and 1x for close work; the CLx 3x gives you a sharper, lighter, and more durable optic at a fixed magnification that is purpose-built for shooters who know they want 3x and want to spend the budget on glass rather than mechanical complexity. For a typical 50-300 yard AR-15 use case, the 3x Prism is the better tool.

The 5.56 Cross Dot reticle is a simplified BDC design: a center crosshair zeroed at 100 yards with elevation reference marks for 5.56 NATO trajectory. It is less informationally dense than the ACSS reticle on the SLx 3x MicroPrism, which means slightly less precision at distance but a faster sight picture for shooters who do not need a chevron-based ranging system. If you are pairing this with a 16-inch carbine running 55-grain or 62-grain ball ammo, the reticle is well matched. For magnified optic selection more broadly, including how prisms compare to LPVOs and 1-8x scopes, see our best LPVO for AR-15 guide.

The decision between CLx and SLx comes down to one question: do you need ACSS reticles? SLx optics ship with Primary Arms' ACSS reticle system (Cyclops, Aurora, Vulcan, Raptor, etc.) which integrates BDC ranging marks, wind holds, and bullet-drop subtensions calibrated to specific cartridges. For a shooter taking 100-yard zeroed shots inside 300 yards, ACSS pays for itself by eliminating dial-up. For a home defense, range plinking, or close-quarters carbine setup inside 100 yards, the simpler CLx reticles do the same job.

The build quality gap is smaller than the price gap suggests. Both lines share the same lifetime warranty, the same hardcoat anodized aluminum housings, and similar lens coatings. SLx gets glass refinement, slightly better illumination uniformity, and the ACSS reticle library. If your build budget is constrained and you do not need BDC, CLx is the smarter spend; route the $60-$100 you save into a quality mount, ammunition, or a backup iron sight. For a full build-level look at how to balance optic, trigger, and accessory spend, our AR-15 builder lets you mock up the complete platform with cost rollup.

The CLx line refresh is the most aggressive budget-tier move from a mainstream US optics brand in over a year. Holosun and Sig have both drifted upmarket as their entry-level models aged into the $180-220 bracket, leaving a gap below $180 that previously belonged to gray-market imports and no-warranty house brands. Primary Arms filling that gap with four lifetime-warranty optics is a meaningful change in the segment.

The two products to watch are the Enclosed Reflex Sight and the RD-23. The Enclosed at $179.99 is genuinely category-disrupting if it ships at spec; the next cheapest comparable enclosed RMSc-footprint sight is roughly double the money. The RD-23 at $149.99 with a lifetime warranty and solar backup is the cleanest sub-$150 micro red dot on the market today. The two prism scopes are competent and well priced, but they compete in a category where the SLx MicroPrism line is only $45-65 more for measurably better glass and ACSS reticles. If you are buying a prism, do the math on whether ACSS is worth the upgrade for your specific use case.

Pre-order availability is mid-June 2026. The RD-23 is the only one already in the dealer affiliate feeds at KYGUNCO. Expect Brownells, OpticsPlanet, and the rest of the major retailer pipeline to fill in once initial shipments clear in late June or early July.
